The Canon PowerShot SD870 IS was released on August 29, 2007 and was only the second point-and-shoot wide-angle lens camera produced by Canon. The SD870 was seen as the replacement model for the older SD800 that was released in later 2006. The SD870 offers a larger LCD screen (3.0" vs. 2.5") and better resolution (8.0 vs. 7.4 Megapixels) compared to its previous model.

The Canon PowerShot SD870 IS is an 8.0 Megapixel camera with 3.8x optical zoom and uses a Secure Digital (SD) memory card. It has a 3.0 inch LCD screen that offers 230,000 pixels of resolution. The camera offers Genuine Canon Face Detection Technology, a DIGIC III Image Processor with Red Eye Correction, and a Print/Share button for easy printing, directly from the camera.

Note: This troubleshooting guide covers only the Canon PowerShot SD870 IS. Other Canon Camera models will be covered in separate troubleshooting guides.

If your camera"s screen is cracked or broken, it is more than likely that you will need to replace the entire LCD screen. There are two options available: (1) You can go to Canon"s repair request website, or (2) Go to our LCD Repair Guide.

This could be an internal problem and should be covered by all warranties. Check to see if your camera is still on warranty and if it is, then visit the Canon website above to send it it. Otherwise, this may be another problem with the LCD screen and you can replace it by visiting our LCD Repair Guide.

If a circuit on the logic board has gone bad due to trauma or water damage, your camera will not turn on. This will be apparent as your camera will not turn on at all, with nothing displayed on the LCD screen and no LEDs lit up. Follow the LCD repair guide to address this problem.

The Canon SD870 IS Digital ELPH features a compact, stylish case with rounded horizontal edges, and a retracting lens to make it pocket-friendly. With an an 8-megapixel 1/2.5" imager and 3.8x optical zoom lens, the Canon SD870 covers a range of 28-105mm equivalent, a useful wide angle to a moderate telephoto. Exposure is fully automatic, but the user can tweak it with 2.0EV of exposure compensation and four metering modes to handle difficult lighting, while a generous twelve Scene modes keep the camera approachable for beginners. A long-exposure mode in the Canon SD870 IS ELPH also lets you manually set exposure times as long as 15 seconds, and a large 3-inch LCD is the sole method of framing and reviewing images, since the Canon 870 IS has no optical viewfinder.

The Canon ELPH SD870 has a rather wide ISO sensitivity range, from 80 to 1,600, for better performance in dim lighting. Canon also manufactures a line of photo printers, and prides themselves on the level of integration between their cameras and printers. The Digital ELPH SD870 is PictBridge-capable, so is able to print to any printer that supports PictBridge directly, without the need for a computer in the middle. When connected to a Canon printer, though, you can set paper size, print quality, and a number of other parameters, capabilities lacking in basic PictBridge connections.

Intro. The Canon PowerShot SD870 IS is the most appealing camera in Canon"s high-end Digital ELPH line, thanks to its 28mm-equivalent wide angle lens. Canon"s latest product strategy for the Digital ELPH is three-tiered: there is an entry level model (in this case, the PowerShot SD850), the middle-range model (the PowerShot SD870) and the high-end model (the PowerShot SD950). Each model has its own niche, and the SD870"s specialty is wide angle photography.

The Canon SD870 improves upon the SD800, the previous wide-angle model in the ELPH line, with an upgrade from 7.1 to 8.0 megapixels, and an LCD boost from 2.5 inches to 3.0 inches. They"ve also upgraded the screen from 207,000 to 230,000 pixels. Optically the cameras use the same basic lens structure, a 28-105mm (35mm equivalent) lens with a minimum aperture of f/2.8 at the wide end and f/5.8 at the telephoto end. Canon overhauled the SD870"s design, as well, making for a heavier, though smaller camera. Finally, the most obvious design change is the lack of an optical viewfinder, made necessary by the SD870"s large LCD.

Look and Feel. The PowerShot SD870 is, legitimately, about the size of a pack of playing cards. At 180 grams (6.3 oz), there is a good heft to the camera, giving it enough weight to keep steady while shooting. It has a solid feel, and when not in use can easily fit in your hand or pocket for easy access. That said, this is not a unit you want to toss around casually. The casing is a hard plastic with a matte finish; around the lens, our review model has a handsome chrome finish that will show off fingerprints and scratches mercilessly. Also available is a model with a black matte finished ring surrounding the lens. I worry about the LCD screen, but Canon assures me that it has an anti-scratch, anti-glare coating; all the same, sticking this camera in your pocket with your car keys is probably not a good idea for the long term. A small carrying case will go a long way to protect this investment, and I don"t think I"d be overly paranoid to suggest you keep the wrist strap on at all times. The lens extends about an inch out from the front of the camera while in use; when retracted, a sliding lens cover protects it.

The controls for the camera adorn the top and rear of the body. On the top you find the power button, operation mode selector, shutter button, and zoom dial; on the back, next to the dominating LCD screen, you have four buttons for playback, direct print, menu, and LCD display modes, divided into two groups of two by a circular four-way selector wheel and a selector button. A wrist strap attaches to the right side, the left side is blank, and there"s not much to speak of on the bottom other than a tripod mount (aligned with the lens) and a single door allowing access to the battery and the SD memory card. This design, in addition to the Canon SD870"s small size would make it impossible to change memory cards or a battery if the camera were mounted on a tripod.

Interface. You can turn on the Canon SD870 IS two ways: by pressing the main on/off button on the top, which brings you into shooting mode and extends the lens, or by pressing the playback button, which activates the playback mode without extending the lens. The Canon SD870 uses a fairly typical menu-driven system for managing the options and settings available in the camera. Since the average user for this camera is not going to want to have access to high-level settings or fully manual operation, the available options are fairly simple.

As with most Canon digital cameras, there are two types of menu. Technical items, like date and time settings, LCD brightness, and language are available with a press of the Menu button. Shooting settings, such as changing exposure control or the shooting mode, are accessible through the function key embedded in the four-way selector. Remembering where the relevant options are takes a little practice, but given the relatively few buttons and clear labels, you quickly get the hang of it. What I would like to see is the inclusion of an in-camera "help" system. Ideally, on any setting, you press a button and a screen full of text explains what this option will let you do. Few people keep their manual handy, and there are many menu items.

An interesting control in the PowerShot SD870, one that"s been on other high-end ELPH models, is the inclusion of a touch-sensitive system on the four-way selector. Essentially, the selector can be used either to change the shooting mode by rotating your finger around the wheel, or to display an iconic representation of the options available on the selector button itself. Personally, when trying to select a different shooting mode by rotating my finger, I could never find the correct "speed" at which to rotate and engage the camera"s mode-switching capability; and when I did, it would sometimes switch, and sometimes nothing would happen. It seems you have to get used to the style of input the camera"s touch-system expects. In practice, I found it much more effective to just switch shooting modes by using the function button in the middle of the four-way selector. Similarly, while the visual representation of the options available on the four-way selector was interesting at first, it quickly became annoying. In one-handed operation, your thumb rests on the four-way selector for support, and thus, the icons are always showing, obscuring your framing. While you can turn off the "touch icons" feature (which show you the representation of the selector wheel functions), the rotating selection function is always on. I suppose it could be argued that for people with poor eyesight, who can"t see the small text labels on the selector wheel, having a graphic representation of the selector wheel could be useful, as the graphic presented is much larger than the wheel. But because I couldn"t get the silly thing to work reliably, I found it less than useful.

The bad news concerns the SD870"s optical viewfinder. It doesn"t have one. It"s been removed from this model, ostensibly to make room for the large 3.0-inch, 230,000 pixel LCD screen. An optical viewfinder becomes useful in at least two scenarios: when you want to conserve power, and when lighting conditions make it difficult to frame a shot with the LCD. The larger the LCD screen, the more power it draws, so turning off the LCD and using an optical viewfinder instead typically gives the user much greater battery life. So the challenge to the camera designer is to produce an LCD that"s both power-efficient and sun-resistant. In the case of the PowerShot 870 IS, Canon has put a lot of effort into the LCD screen, no doubt aware that without a backup system, a lot is riding on the LCD. The battery is rated to produce 270 shots, a respectable amount for a camera this size, and in practice, I found the screen to be quite easily viewable in all but the most extreme of lighting conditions. Coupled with the fact that the optical viewfinder on the SD800 IS wasn"t that great (it only showed about 80% of the frame and was slightly distorted), removing it entirely isn"t that great a loss. Of course, if using, or having the option to use an optical viewfinder is important in your photography, then this is definitely a factor you may need to weigh. Canon"s betting that most folks want a 3-inch screen on a small camera more than an inaccurate optical viewfinder, especially since an optical viewfinder so badly shows what the SD870 IS"s 28mm lens can do.

You can transfer files from the Canon SD870 with the included USB cable, which operates at a respectable 1,053 KBytes per second. You can also view images and videos on an RCA-jack-equipped television via the included A/V cable.

Modes. The PowerShot SD870 has three basic shooting modes: Movie mode, Scene mode, and Record mode, all selectable from the switch on the top of the camera.

Movie mode is fairly simple to start: You flick the switch on the top of the camera to the left, and you"re all set to take movies. There are a few options when working in movie mode including changing the color profile, the white balance, and some software-related options that let you swap or emphasize colors in the scene you"re shooting. Optical image stabilization works great, and I recommend you keep it enabled while shooting a movie, given the small size and weight of the Canon SD870 IS.

The most direct use of Movie mode is in 640x480, 30 frames per second. You can also cut the resolution in half (320x240) or use "LP" mode (a higher compression rating) to increase the length of time available for shooting a movie. In this main mode optical zooming is disabled while a movie is being shot, but you can still zoom in and out digitally. Also available is a compact movie mode geared toward sending movies by email, where movies are shot at one-quarter resolution (160x120). Finally, Time-lapse video mode lets you create a movie based on frames captured every one or two seconds. Overall, I found shooting movies with the SD870 IS to be quick and efficient, and the playback quality was better than I was expecting from a small unit geared toward taking photos.

The Canon SD870 has a good system available to the user to keep images organized. The camera offers seven category types with which the user can file images for later reference. These categories include People, Scenery, Sports, three numbered categories, and To Do. You assign categories by putting a checkmark by each category for which the image in question is applicable; for example, if your image contained both people and scenery, you could check both categories. This is useful for finding images later, in that you can filter all the images on the memory card with certain categories.

The Canon SD870 has a great slideshow mode that"s quite effective given the large screen. You can select all photos on the memory card or only a certain subset of images. After you"ve selected your images, you can select the duration of each slide and whether the slideshow should repeat when finished. Unfortunately, my lovely quick cross-fade is missing from the list of options; instead, you can choose from some rather clunky movement transitions, or use none at all.

The Canon SD870 also allows the user to configure the action of the Playback button: by default it enters and exits Playback mode. It can be reconfigured to start a slideshow, or activate the sound recorder; doing so, however, makes it less obvious how to get back to shooting mode. Fortunately, the camera is designed with shooting priority in mind, and half-pressing the shutter release button always takes you to shooting mode.

Special Features. The "IS" designation for the PowerShot SD870 IS stands for Image Stabilization, which has been a feature of the Digital Elph PowerShot series since the SD800. Canon developed the original optical image stabilization system, which uses a series of gyroscopic sensors to detect movement of the user and compensate by moving the lens in the opposite direction. It"s extremely effective in reducing the blur from camera shake. I find it an absolute necessity, allowing me to take photos in more challenging situations for the camera and get much better results. In the real world, I think it works very well; I can take photos at shutter speeds as low as 1/15 second and get very crisp images.

Canon also features face detection on the SD870, with the ability to detect up to nine forward-looking faces. In operation, face detection works by showing you a box around the face of the person you want to photograph. When the camera can see two eyes, face detection works splendidly; however, when the subject turns their face away from the camera, to even just a slight degree, face detection doesn"t lock onto the face. When it works, face detection is quite useful; it guarantees the subject"s face will be in focus, and not the background. Flash settings are also adjusted automatically, with red-eye reduction, to give a more pleasing photograph. When it doesn"t lock on, however, you"re stuck with regular focusing, which can produce a result different from what you intend. All you have to do is tell your subject to look at the camera, the face detection box activates and locks on, and you"re set. In testing, it took a fair bit of effort to fool face detection; it had no problem with eyeglasses and even sunglasses. It would rarely detect something "face-like" that wasn"t a face.

Storage and Battery. The PowerShot SD870 ships with a 32-megabyte SD card. Given that the camera sports an eight-megapixel sensor, the highest-resolution photograph the camera will produce results in an image that"s 3,264 high by 2,448 pixels wide, and takes up an average of 3,436 kilobytes (almost three-and-a-half megabytes). According to Canon, that will give you a grand total of eight photographs on the included card. Thus, it makes a great deal of sense to get yourself a shiny new SD card, preferably in the 2 to 4GB range. Happily, as of October 2007, SD cards are about the cheapest memory you can find.

The battery provided with the SD870 is a 3.7-volt, 1,120 mAh lithium-ion battery. According to Canon, this will give you 270 shots, and in practice, I can say I used it on and off for a couple of days before getting a "low battery" warning icon. The recharger that ships with the SD870 is undeniably portable, with a sideways-folding plug that is quite ingeniously designed, at least for users in the Americas. Unfortunately, the recharger is a space hog on power-bars, though it does better on wall outlets. Recharging time was less than an hour.

Shooting. As I indicated earlier, I had a bit of difficulty adjusting to one-handed shooting with the SD870 IS. The SD870"s design is a trade-off between a shooting camera and a camera that"s convenient to carry. While it may not be ergonomically designed for optimum shooting, I cannot deny that the Canon SD870 IS is easy to take anywhere, any time, and take excellent pictures.

"The camera that gets taken is the camera that takes photos" is a maxim I usually tell people, especially when they"re debating buying a point-and-shoot rather than an SLR/lens system. As much as I love my SLR, there are some places I won"t bother to take it, where a camera like the SD870 is an excellent companion.

In practice, I found shooting with the SD870 to be straightforward and to the point. Power-on takes about one second, meaning that at a family gathering, I was able to grab photos of the nephews quickly and conveniently. I"ve always liked having the zoom rocker linked to the shutter button as opposed to a separate control, as it is more intuitive for me. It took about 1.5 seconds to go from 28mm to 105mm, and the zoom was quick and responsive to my touch. Standard Digital zooming wasn"t as useful for me, as the image quality suffered (to my eyes) unacceptably. However, Canon has implemented a useful system where if you select an image size smaller than Large (ie., it uses less than the camera"s eight megapixels), the camera can use the sensor to zoom rather than have to interpolate the image. For example, if you select small mode (640x480), you can zoom out as far as 15x (that"s almost four times the optical zoom of 3.8x) and the image produced won"t be the least bit pixelated. This results because the camera is only using a 640x480 chunk of the sensor to take the picture.

The SD870 offers a continuous shooting mode, at the stated 1.3 frames per second, regardless of whether the camera was set to record large-size, superfine compression images or the smallest size of image. This is a bit of a decrease from the SD800, which had a shooting speed  of 1.7 frames per second. You definitely get a speed increase when shooting in continuous mode; shot-to-shot in single shot mode, you can take one shot about every two seconds. You can also set a self-timer, at either 2, 10, or a custom-set number of seconds.

ISO selection on the SD870 is done by clicking the four-way selector upward, and is available only in the regular camera mode. In Manual and Digital Macro modes, you have access to the whole range of ISO speeds, from 80 to 1,600. In the other camera modes you can only select between Auto ISO shift and HI Auto ISO shift. Auto-ISO shifting is a new feature to the SD870, and it"s a logical evolution that has made its way down from the world of prosumer and professional SLR cameras. Essentially, the camera is able to examine the current lighting conditions and select not only an aperture and shutter speed, but an ISO speed that"s appropriate for a proper exposure. Auto ISO shift mode will also select ISO speeds outside the user-selectable range, in 1/3 EV stops. Unchecked, using Auto ISO shift mode this could lead to some noisy images, because increasing ISO speed is like turning up the volume on a radio station with poor reception; you might make out the program a little better, but you also hear more of the static, too. Therefore, regular Auto ISO shift mode is capped at ISO 200. If you want to go higher, High Auto-ISO shift mode offers automatic ISO selection up to ISO 800. If you want to max out the ISO and go to ISO 1600, you have to select it specifically from the ISO menu, and it will only be available in manual and digital macro modes.

Exposure. The Canon SD870 IS offers exposure control in most of its modes. The user can override the camera"s metered exposure selection by up to two stops in either direction, in 1/3 stop increments. This is useful where you have unusual lighting conditions, such as taking a photo of a sunset; typically, the camera will want to over-expose the sky to get a brighter image in the foreground, but there isn"t as much light available and you end up blowing out the sky. Underexposing lets you get a better shot. The Canon SD870 also offers direct access to a long shutter mode while adjusting exposure control, by pressing the DISP button. Doing so will let you have direct control of the shutter speed, between one and 15 seconds. Enabling long shutter mode automatically engages a noise reduction mode, but it seems to turn off Auto-ISO shift. In long shutter mode the Canon SD870 will default to the widest aperture available, so outside of night photography, it becomes really easy to overexpose images.

AE locking is also an option on the Canon SD870. To use it, you half-press the shutter to select focus points and exposure settings, and then while holding the shutter down, you press up on the four-way selector (ISO selection). This engages the AE lock. Forget about doing it with one-hand; this is definitely a two-hand operation. It"s also possible to lock the flash exposure level with a similar operation, if the flash is set to always-on mode.

Autofocus. Autofocusing results with the Canon SD870 were a bit of a mixed bag. With posed shots, I found the camera had no trouble sorting out the obvious focus points, but occasionally with more "spur of the moment" shots the camera would miss the subject. With face detection on a face-on subject, I never had a problem with the camera achieving the subject focus perfectly. However, in low-light, and especially if the subject"s face was even a few degrees off from face-on to the camera, face detection wouldn"t "lock on" to the subject. According to the lab setup, the camera was able to successfully focus in as little as 1/16 foot candle of light. In all cases, there is a focus-assist lamp (that you can disable) which works very well in establishing a proper focus.

For checking focus, the Canon SD870 IS has a very interesting display mode in Playback that first shows you what area the camera focused on, and it gives you a slightly zoomed version of the image in the lower right corner. If you hit the zoom toggle, that image zooms in more and more. If the shot was made in Face Detect mode, or if there was more than one AF area selected, you can press the Set button to switch between the active areas to verify focus there as well.

Image Quality. The Canon SD870 produces well-exposed, nicely-saturated photos. Looking at the shots from our test lab, colors by default are slightly over-saturated, pushing the red and blue tones a bit. Of course these are just the default settings - you can adjust through no less than eleven color presets to adjust the way colors are presented, including Vivid, Neutral, Sepia, Black and White, Positive Film, Lighter Skin Tone, Darker Skin Tone, Vivid Blue, Vivid Green, Vivid Red, and Custom.

In evaluating the image quality of the photos produced by the SD870, I"m going to consider a few things: sharpness, ISO noise, and noise reduction, image characteristics inherent with the lens, and flash performance.

The Canon SD870 does apply sharpening by default in all of its color modes, but doesn"t go over the top in doing so. Fine image detail is well preserved in the process, and there are few indications of edge enhancement artifacts. If you want to have more control over image sharpening, you can fine-tune the effect with custom color settings, as indicated above.

The image quality of the Canon SD870 at ISO 80 is very good, but does get noisier as the ISO rating increases. The question is, at what point does it become objectionable? Our shots in the lab show noise to be a factor beginning at around ISO 200; it interferes with fine detail at ISO 400, and by ISO 800, it destroys fine details altogether. Still, we were able to print good quality ISO 800 images at 8x10, and 11x14-inch images looked great from 80 to 400. Even the ISO 1,600 image that looks so mushy at 100% onscreen looks pretty good at 4x6. Noise reduction is applied to long-shutter images, with excellent results and very little disruption to areas of subtle contrast. At levels of higher ISO, noise reduction also kicks in, smoothing out color problems but obscuring fine detail in the process. Check out the Exposure tab for more on image quality.

The lens construction of the Canon SD870 seems to be optimized to produce a quality image at the telephoto end of the lens. At that setting (105mm) you see virtually no image distortion, chromatic aberration, or corner softness. By contrast, at the wide setting (28mm), images show significant levels of all three - 1.1% barrel distortion (to be expected on a 28mm wide angle lens), 10+ pixels of chromatic aberration on either side of target lines, and images were very soft in the corners. But corner softness was evident only in the very extreme corners; for the most part, the plane of focus was impressively flat. See the Optics tab for more detailed analysis.

Flash performance of the Canon SD870 is average. When dealing with the lens at its wide-angle setting, the flash is unable to cover the entire frame (this is not unusual, especially with small cameras like this). Coverage is better when the lens is zoomed in to telephoto. In both cases you need to push up exposure compensation by one stop, as the light produced by the flash underexposes the whole frame somewhat, at least in the lab. In practice you will typically be dealing with lighting a subject in the context of a background. Canon"s tech specs show the flash as being good up to thirteen feet (4 meters) at wide-angle, and six feet (2 meters) at telephoto. In practice our lab shots more or less confirm these numbers; however, our results at telephoto show that you should expect to see slightly underexposed images when approaching the maximum range of the flash (six feet).

Appraisal. There"s a lot to like about the Canon PowerShot SD870 IS. Perhaps the best selling feature is the large and lovely 3-inch LCD screen, which makes an excellent playback device. Moms who want to carry around their own "brag book" of weddings and newborns have an excellent choice here, although I found the slideshow options a bit wanting. This is not a camera for someone new to digital photography, but rather for someone who knows their way around a digital camera: there are no in-camera help settings, the button text is concise and uses terms and an iconography that, while standard in the industry, could be confusing to new users. For people comfortable with a digital camera however, they will find themselves quickly at home with the Canon SD870. The layout of buttons and menus is intuitive, and the camera"s operation is quick and responsive. As a shooting-priority camera, you can always take a photo by just pressing the shutter-release button (although the lack of a optical viewfinder may make quick framing difficult). On automatic, the camera does a good job of capturing respectable images. For photos of people, as long as the camera can see both the subject"s eyes, there should be no problems at all getting a pleasing picture.

The Canon SD870 continues with the features that made the PowerShot SD800 a great camera: an excellent 28mm wide-angle lens, Face-detection autofocus, optical image stabilization, plenty of scene modes, and a few important tweaks to the overall operation of the camera. Even movie mode benefits from the wide-angle view, making personal up-close family videos quite easy and fun. The SD870"s 8-megapixel sensor delivers resolution capable of delivering good quality 11x14-inch prints up to ISO 400, an impressive feat indeed. Canon has increased the size of the LCD but removed the optical viewfinder; optical viewfinders being something of a joke on most digital cameras with extraordinary optics, most users won"t miss it. The 3-inch LCD more than makes up for the lack of a viewfinder, and works well in bright sunlight. At 180 grams (6.3 oz), the Canon SD870 IS can fit in almost any pocket, and uses a battery that can take a pretty decent number of photos. It"s a lot of camera fit into a small package, and I think it"s a great fit for the experienced digital camera user who needs a reliable, take-anywhere shooter that shows off its photos well. And I can"t emphasize enough how great it is to have a 28mm wide angle lens in such a small package, making the Canon PowerShot SD870 IS a clear Dave"s Pick.

The Canon PowerShot SD870 IS"s performance here is pretty good overall. Start-up time is quite fast at about one second. Shutter lag at wide angle and telephoto zoom is very good, at 0.38 and 0.42 second respectively, and "prefocus" times (half-pressing and holding down the shutter button before the final exposure) are very fast, with a shutter delay of only 0.088 second. Shot-to-shot cycle times are on the slower side of average these days, at about 2.2 seconds for large/superfine JPEGs. The SD870"s continuous shooting speed of 1.3 frames per second is only average for its class these days, however it captures frames continuously at this rate. Flash recycle time is a bit below average, at 8 seconds after a full-power shot. Connected to a computer, download speeds are reasonably fast, so you won"t feel a need for a separate card reader. Bottom line, the Canon SD870 IS is a good camera for average shooting conditions, though you"ll need something a little zippier for sporting events or active children.

The SD870 IS (known in Europe as the IXUS 860 IS and in Japan as the IXY Digital 910IS), announced in August, is a replacement for the SD 800 IS (IXUS 850 IS), one of last year"s most popular ultra compacts. It retains the SD800"s optically stabilized 28-105mm (equiv.) zoom lens, making it one of the only cameras in this sector of the market with this useful wideangle capability, and throws a few new or upgraded features into the mix, including improved Face Detection AF and red-eye reduction in playback mode, and Auto ISO shift. The other changes are fairly predictable, with a larger screen and just under one million extra pixels. The highlights of the specification are as follows:

The SD 870 IS is a distinctly gentle revision of the SD800 IS, launched around a year ago. It offers a larger screen than its predecessor but it loses the optical viewfinder to keep the overall body size virtually unchanged. It also gains a higher resolution sensor but loses out in terms of continuous shooting speed, with the frame rate dropping from 1.7fps to 1.3, suggesting the buffer has not been increased. Other noticeable gains include a useful user-definable function button, a touch control wheel and Auto ISO-shift function.

There are two cable options for connecting the PanelDue, both options are included with the PanelDue V3 kit. Option 1 is the included 4-wire cable with Molex KK connector ends. Option 2 is the included 10-wire ribbon cable. For some boards, both cables need to be plugged in to enable both TFT panel and SD card socket.

The length of the 4-way cable is not critical, however the resistance per conductor should not exceed 0.1 ohm. The SD card socket on the TFT panel will not be functional. The cables supplied by Escher3D and Duet3D are about 800mm long. There have been reports of cables up to 1500mm long being successfully used. Take care to route the cable away from motor and endstop cables. Twisting the cables may help prevent cross talk interference.

A PanelDue can be connected to connector IO_0 using a 4-core cable wired like the one shown in the images below. The 4-wire cable supplied with the PanelDue has a 4-way Molex KK connecter on each end, but is supplied with a 5-way Molex KK connector for use with Duet 3. You will need to rewire one end. The 4-wire cable does not allow access to the SD card socket on the PanelDue.

Older versions of the Duet 2 WiFi/Ethernet need both the 4-wire and ribbon cable to be plugged in to use the TFT Panel and the SD card socket, when connecting PanelDue v2.0 or v3.0.

Use a 4-core cable terminated in a Molex KK or compatible connector at the PanelDue end and a 2x4 Dupont-style connector at the Duet end. This plugs into the end of the expansion connector. See https://miscsolutions.wordpress.com/pane....

In order to use the SD card slot on the PanelDue, you must use the ribbon cable option. If you do not wish to use the SD card slot, it"s recommended to use the 4-wire cable option described in Option 1.

The Duet 3 MB6HC has no PanelDue_SD socket. To use the external SD card, it requires RRF 3.4 or later, and a special wiring scheme; see "Duet 3 MB6HC using ribbon cable" section below.

Connect a 10-way ribbon cable between socket X5 on the PanelDue and socket CONN_SD (Duet 2) or PanelDue_SD (Duet 3). The connector is a standard 10 pin 2 row 2.54mm pitch box connector that accepts IDC connectors for 1.27mm ribbon cable.

Caution: if you are using a thermocouple and/or PT100 daughter board, the use of long ribbon cables between the Duet and PanelDue may affect communication between the Duet and the daughter boards, because the ribbon cable connection to the SD card on PanelDue uses the same SPI bus as the daughter boards.

Although the Duet 3 MB6HC does not have a connector for the PanelDue ribbon cable, if access to the SD card on PanelDue is required then this is possible using a special wiring arrangement. You must use RepRapFirmware 3.4 or later, and you must enable the external SD card using this command:

where cs_pin is the pin that the SD card CS line is connected to and cd_pin is the pin that the SD card detect pin (if available) is connected to. For these pins, if you are not using a temperature daughter board then we suggest that you use CS0 and CS2 respectively on the SPI daughter board connector to simplify the wiring; otherwise use the output pin and the input pin on one of the IO connectors. So the M950 line would look like this:

Note: if you are using an older version of either PanelDue 7i or PanelDue 5i, or a non-integrated version of PanelDue, then those do not support the CD signal. In that case you should omit the second port, for example:

The card detect signal (CD) is used to tell the Duet whether a card is inserted or not. Non-integrated versions of PanelDue (V2, V3) and older versions of PanelDue 5i and 7i (v1.0 of the 5i and v2.0 of the 7i) do not provide a card detect signal.

Duet 2 boards do not support the card detect signal on the external SD card, so can never tell whether a card is inserted or not except by trying to read it, and can"t detect a card being removed. No modifications are required connected older or newer PanelDue, or other external SD card adapters, to Duet 2 boards.

Duet 3 boards do support the card detect signal. Newer versions of the PanelDue 5i and 7i (v1.01 and later of the 5i and v2.01 and later of the 7i) provide this signal.

However, if you use a non-integrated versions of PanelDue or older versions of PanelDue 5i and 7i with Duet 3, it is necessary to ground the card detect signal, or the firmware will permanently think no card is inserted. There are a number of ways to achieve this.

This mod will enable the card detect signal. See the pictures below showing how to modify a PanelDue 5i v1.0. Connect a wire (thin enamelled copper in this instance) from the SD card socket Card Detect pin to the appropriate pin on the ribbon cable connector.

On the Duet 3 Mini 5+ you can ground the card detect signal by bridging pins 2 and 4 of the EXP2 connector as shown here. The firmware will see the SD card as always being present.

Generally it is best to run the latest version of the PanelDue firmware that is supported by the RepRapFirmware version on your Duet mainboard. See: Installing and Updating PanelDue Firmware

From RRF v3.2, PanelDue firmware releases are co-ordinated with the RRF release, and share the same version number. Use the PanelDue firmware version that matches your Duet mainboard"s firmware version.

PanelDue will display the bed heater H0 first (even if it is disabled), then iterate the defined tools. It then iterates the defined heaters below this. It expects a 1:1 relationship between tools and heaters. This means:if you have a machine that uses one heater for more than one tool (eg a 2-into-1, filament-swapping hot end), it will display more tools than heaters. Tools may not line up with their respective heaters.

The PanelDue also iterates the heaters from the first defined heater to the last, including all heaters in between, whether defined or not. This means if you have a heater defined on H0 (bed) and one on H5 (Duex output), it will show all the ones in between, eg H0, H1, H2, H3, H4 and H5. For an example, see |https://forum.duet3d.com/post/136207|this forum post|. Ideally, configure heaters on consecutive heater connections.

Due to constraints on display resolution, PanelDue can only display 7 heaters in total on 5" and 7" panels, and 5 on 4.3" panels. If there are more heaters and/or tools than this, some columns will overlap.

These restrictions are largely removed in later versions of the PanelDue firmware. However, they will require you to update RepRapFirmware on your Duet mainboard.

You can use the external SD card socket on the LCD panel if you have used a ribbon cable as described above. Please note, the SPI interface provided by this SD card socket is much slower than the on-board SD card socket built into the Duet. Therefore we recommend that you do not upload files to this card over the network. Use the external SD card socket only if you want to write files to the SD card on a PC and then move the SD card to your printer.

Caution! Do not use an SD extender cable from the SD socket on the Panel Due. Some types of SD card extender cable have been found to damage the SD card socket. Damage to the SD card socket from using an extender cable is not covered by the warranty.

You will need to make a custom 5-way cable using this table of connections. For the PanelDue 1.1, the X5 connector pins are numbered from the bottom end of the connector (the end close to the X5 legend). On the Duet 0.6 and 0.8.5 you need RepRapFirmware 1.17d or later to get support for the second SD card.

There are two types of controller chip commonly used in these controllers: ST7920 and ST7567. Some Duets support one or both of these types - see below for details. Both types use a menu system stored on the SD card, see 12864 display menu system.

An example of this is the Fysetc Mini 12864 Panel. The controller chip is run from 3.3V, so these displays normally include level shifters which tolerate a wide range of input voltages.

Duet 3 Mini provides two 2x5 ribbon cable headers for connecting a Fysetc 12864 Mini Panel version 1.2 or 2.1 (not 2.0) or compatible ST7567-based controller. When using a version 2.1 controller, the colours of the three Neopixel LEDs built into the display can be set using the M150 command with LED type parameter X2.

Use the pins +5V, GND, IO_0_OUT and IO_0_IN on the IO_0 header (Duet 3), or +5V, GND, TX and RX on the PanelDue header (Duet 2). These should be connected to +5V, GND, TX and RX on the TFT, making sure that TX and RX are swapped.

There is now an RRF config.ini (on the SD card root). It needs to be renamed from config_rrf.ini to config.ini (replacing the original one for Marlin) for flashing of the firmware.

The GT has a passion for gaming, which is evident in the 144Hz display – the fastest refresh rate in the family. The touch sampling rate is 270Hz. This is a 6.6” LCD with 1,080 x 2,460px resolution (20.5:9) and it can render 1 billion colors (it supports Dolby Vision as well). Peak brightness is 650 nits (500 nits typical) and the panel uses DC dimming. Also, it is guarded by Gorilla Glass 5 (the X3 GT had Victus).

The first Digital IXUS, released in June 2000 fitted the technology of the PowerShot S10 into a body similar to the APS IXUS II.CF cards to SD cards to create thinner cameras.

All models introduced before 2010 use RGBG Bayer filter (except the original Digital IXUS, which uses a CYGM filterCCD sensors made by Sony. IXUS 300 HS/PowerShot Digital ELPH SD4000 IS/IXY 30S introduced in May 2010 and all following models have back-illuminated CMOS sensor. Images are recorded as JPEGs. Raw image files are not accessible without the use of third party firmware such as CHDK.
