3.5inch RPi LCD (A) and 3.5inch RPi LCD (B) are hardware compatible with each other (uses different driver), and can be mutually substituted in most cases. (A) for low cost ver. while (B) for IPS ver. with better displaying.

Why the LCD doesn"t work with my Raspbian?To use the LCD with the Raspberry Pi official image, driver (SPI touch interface only) should be installed first. Please refer to the user manual.

The PWR will keep on and the ACT will keep blinking when the Raspberry Pi starts up successfully, in case both of the two LEDs keep on, it is possible that the image was burnt incorrectly OR the TF card was in bad contact.Which power supply should I use?It is recommended to use a 5V/3A power adapter for the Raspberry Pi other than USB connection, otherwise the Pi may failed to start up because the PC"s USB port might have not enough power.

Since the first-generation Raspberry Pi released, Waveshare has been working on designing, developing, and producing various fantastic touch LCDs for the Pi. Unfortunately, there are quite a few pirated/knock-off products in the market. They"re usually some poor copies of our early hardware revisions, and comes with none support service.

I am doing a project to build a mobile desktop (aka tablet + laptop case + case). I have bought a clam shell type case that can house 10.1 inch screen IPS LCD screen, that has 40 pin LVDS.

But the driver board wont fit my clam shell case. I was wondering if there is another option that can use GPIO pins and directly drive the screen. I am quite a newbie to display internal technology. What drivers/chips/pcbs/connectors/technology should I look for? Is this even possible. Any pointers would be very helpful.

@memjr: sorry, but absolutely incorrect! The Pi GPIO can be used as DPI, so you can drive all screens which have DPI interface directly. Size doesn"t matter, so you can drive bigger screens as well.

@OP: the Pi does not have a LVDS interface, so you can"t connect the display without glue logic. The simplest interface to LVDS is an LVDS transmitter. It takes DPI as input and converts it to LVDS. This will allow to drive resolutions up to thr transmitters capability (i.e. FHD = 1920x1080 pixels).

This gives you some idea viewtopic.php?t=157109&hilit=Lvds+40pin+gpio. Below is an example of driving LVDS FHD display from "DPI + glue logic". You need some DIY skills for sure as such an solution is not available off the shelf (AFIK)

Use a 7 inch TFT LCD with 800x480 and 8 bits color depth, 60Hz frame rate as example, you are talking about 17.69 gbits/sec bandwidth. So there is no way GPIO can supply that.

@memjr: sorry, but absolutely incorrect! The Pi GPIO can be used as DPI, so you can drive all screens which have DPI interface directly. Size doesn"t matter, so you can drive bigger screens as well.

2) Get a DPI displays and use your GPIO-DPI interface. Problem is I can"t find any DPI displays at 7inch or higher sizes. Another option is to use DSI-DPI bridge but only available as a chip and not as a PI-compatible board.

There is also RGB/LVDS to mipi DSI board (https://m.made-in-china.com/product/5-0 ... 60301.html). However I am not sure if the TFT LVDS panel I have is LVDS/RGB or something else. These converters also seem to not be available for 7.0 or higher sizes screens.

I understand. For that vision to become reality both Pi foundation and display industry to coincidentally converge on usb-c as main interface for display.

Option 1 is using the TI SN65DSI84 DSI to dual-link LVDS chip, which does have some support - aBugsWorstNightmare has made up a board using that family (SN65DSI8[3|4|5]). Read viewtopic.php?t=305690&start=350 for the details of that.

Option 2 uses a Lontium LT8912B chip. There is a driver in mainline Linux for it, but they seem to be very secretive over any information. Also in that datasheet it say "Only Non-Burst Mode supported", which will be a problem as the Pi can only output DSI at particular link frequencies (it"s an integer divider from a PLL).

It seems building a interface/driver is virtually impossible because there is no standard for building DSI displays and the companies don"t share specifications/timing diagram. Please correct me if I am mistaken.

Would never ever buy that product based on this spec. So either ask them to provide the full spec or don"t buy it! You were not only missing details on the display interface, there is not detail on the touch in addition (yes, the connector says it"s USB, but what if you want to use it via I2C?).

Get in touch with Vera (vera_yuan _AT_ dlcdisplay.com). Once was in touch with here; she"s very responsive and could provide the requested info as well as giving advice on different (upcoming) products. You can buy DLC via distribution or (if you"re lucky and they carry stock of the particular TFT) digikey.

However, I did came across this https://forum.armbian.com/topic/22815-c ... uchscreen/ that says OrangePi has a 10.1 inch screen that supports MIPI/DSI interface.

It says it is using Ilitek ILI9881c panel controller to drive the display. Was wondering if this controller would be compatible with 10.1inch display. I guess I would have to ask NXP or the company that provides boards with this display. Just thought I would share this info and ask if you have any idea/prior information on this.

Ilitek ILI9881c is a TCON - a controller which is part of the display. There is a driver in the kernel source which has init code for several displays already. There are others here on the forum who were trying to get their ILI9881 based display running as well viewtopic.php?t=339281

That Orange Pi display appears to use 4 DSI data lanes, therefore you"ll only have a chance of getting it to work on a CM4, not a regular Pi (which only exposes 2 data lanes).

Maybe someone reading here has one and can check if there are some labels on the back telling us what it is. Or they were also using a "modified" RockChip driver which allows for passing DSI init sequence parameters (remember viewtopic.php?t=339281 ... lot"s of 10.1in DSI related questions atm ...)

You’ve been incredibly patient: thank you. The official Raspberry Pi touch display is on sale today, priced at $60 (plus local taxes and shipping): you can buy it at RS Components/Allied Electronics and at Premier Farnell/Newark. Other sellers will be receiving stock later this week.

Two years ago, I began the process of looking for a simple, embeddable display for the Raspberry Pi. I honestly believed it would only take us six months from start to end, but there were a number of issues we met (and other products diverted our attention from the display – like Rev 2.1, B+, A+, and Pi 2). But we’ve finally got there, and I thought you might be interested in learning about our journey.

HDMI is the system we all know and love, it allows us to communicate with monitors up to 4K and has a relatively low signal swing to reduce EMI. There are lots of other very useful bits of the specification such as CEC (a communication channel between the TV and the Pi that allows us to receive input from the TV), EDID (a method of automatically identifying the different formats the TV supports) and a hotplug signal allow the Pi to know when you plug in the cable. The only problem with HDMI is that the electronics required to convert from HDMI to the native panel interface can be quite expensive.

DPI (Display Parallel Interface) is a 24-bit parallel interface with a clock and various synchronisation signals totalling 28 signals, all of which switch at a rate of around 70MHz. This interface has been phased out of tablets/phones because the electromagnetic noise created and power consumed by all those wires. Although it is possible to directly talk to a DPI display through the GPIO connector on a Raspberry Pi it would leave no GPIOs left for people to connect other HATs. DPI displays are available everywhere though, and are relatively cheap!

DSI (Display serial interface) is a high-speed serial interface based on a number of (1GBits) data lanes. The total voltage swing of the data lines is only 200mV; this makes the electromagnetic noise created and power consumed very low. Unfortunately, DSI displays are only really created and sold for special purposes (i.e. when a mobile phone manufacturer wants to make a new phone), and although they can be available to buy, manufacture of the devices is subject to the lifetime of the phone!

DBI (Display Bus Interface) is an old display technology that usually has inbuilt frame storage to reduce tearing, due to the memory and hardware it makes DBI screens expensive.

So our solution to this problem was to employ both DSI (to avoid using up all the GPIOs) and DPI (easily available screens in suitable resolutions) and a bridge chip/conversion board to convert between the two.

Of course lifetime is one of the most important requirements, because if a display only has a lifetime of a few months (or the manufacturer is uninterested in guaranteeing a minimum lifetime), we would have to repeat the whole development cycle once more. So we can’t just buy a display that’s used in your standard iDevice, because it is likely to be cancelled when the iCompany decides to move to another manufacturer!

When looking for a device, we needed to look for what are termed ‘Industrial’ LCD displays. These tend to have better-quality metrics and guaranteed availability.

Our first PCB to do the DSI to DPI conversion was completed back in mid-2013. The board used a Toshiba bridge chip to convert the DSI signals to DPI ones. I spent quite a bit of time getting the Raspberry Pi to talk to the bridge device, and then got it working and displaying an image (yay). We then took it to our local EMC test facility to investigate how easy it would be to pass CE and FCC electromagnetic compliance.

When electrical currents flow around a circuit board, they create electro-magnetic fields, which can be picked up by other electronic devices. Maybe you remember what used to happen to your CRT television when your mum turned on the hoover (sorry for those of you without any experience of analogue television). This was becoming a problem for television and radio receivers; when I was a kid and plugged in my Spectrum 48K, the radio wouldn’t work properly any more. So the powers that be introduced new rules about the amount of energy a device can output at various frequencies from 25MHz up to a couple of GHz. You have to make sure your electronic devices do not cause interference, and are not susceptible to electronic interference.

Unfortunately, DPI is 1.8V signal swing, and although much slower, it needs 28 signal wires, meaning 28x more paths with the same edges switching up and down at the same time. This gives us an output looking something like:

The next step was to understand why the EMI is so bad, so we tried redesigning the board so it looks like a HAT (it’s not actually a HAT because there is no EEPROM for device tree information), and added an Atmel device to control the power/reset and PWM for the backlight. We also went through three different iterations of adding chokes to improve the noise conducting down the power supply cable, and manipulating the route of the DPI signals to improve the path of the ground return.

The first displays are supplied as a kit which requires some initial construction. Alex Eames from RasPi.TV has helpfully provided a video showing how to do it.

The display module integrates the LCD display with a conversion board that should be plugged into the Raspberry Pi through the display connector. Be aware that the connector is the same as the camera connector, but the two are not compatible, so be careful to correctly identify the display connector first.

The 15-way FPC connector should already be plugged into the display conversion board with the silvered contacts face-up. You can then plug the connector into the Raspberry Pi with the silvered connectors inboard (facing towards the USB connectors).

Attach an official 2A Raspberry Pi power supply to the display board “PWR IN” connector, then attach a standard uUSB connector from the “PWR OUT” connector to the Raspberry Pi.

The Raspberry Pi will now automatically detect the display and use it as the default display (rather than HDMI), although HDMI will still be initialised. If you’d prefer for the HDMI display to stay as default then add:

It is possible to use both display outputs at the same time, but it does require software to choose the right display. Omxplayer is one application that has been modified to enable secondary display output.

Please note, you may need to increase the amount of memory allocated to the GPU to 128MB if the videos are 1080P, adjust the gpu_mem value in config.txt for this. The Raspberry Pi headline figures are 1080P30 decode, so if you are using two 1080P clips it may not play correctly depending on the complexity of the videos.

The Raspberry Pi display has an integrated 10-point touchscreen (a bit of an overkill, but it does seem to work well). The driver for this touchscreen outputs both standard mouse events and full multi-touch events, and therefore can work with X as a mouse (although not brilliantly – X was never designed to work with a touchscreen!).

Kivy is a Python GUI development system for cross-platform applications. It is designed to work with touchscreen devices (phones and tablets), but also runs on the Raspberry Pi. To install Kivy onto your Pi follow the instructions at

From the videos you can see how capable the interface is. I’m in the process of developing a touchscreen application for an installation at home to control a safety and heating monitoring system, so you’ll probably hear more about that at some point!

Last of all, if you’d like a stand for your display, you could do a lot worse than to take a look at the 3D-printed one that Matt Timmons-Brown has designed; we like it a lot. You’ll find his model on Thingiverse.

Long time enjoyer of this driver. Truly awesome. Generally I"m using it with an ILI9341 generic from Hiletgo Amazon, However I just got a new screen from China (an ST7789 according to specs) that"s an 8 pin SPI TFT OLED display. No matter my wiring or my command lines, it just does not want to work. I"ve got to the point where the Reset pin will light up the backlight but it wont" go any further.

Command: cmake -DST7789=ON -DGPIO_TFT_DATA_CONTROL=25 -DGPIO_TFT_RESET_PIN=24 -DGPIO_TFT_BACKLIGHT=23 -DSPI_BUS_CLOCK_DIVISOR=40 -DUSE_DMA_TRANSFERS=ON -DDISPLAY_BREAK_ASPECT_RATIO_WHEN_SCALING=ON ..

Everything compiles just fine and even turns on the backlight, but there still is a black screen. The only thing I"ve changed in config.h was to uncomment // #define UPDATE_FRAMES_WITHOUT_DIFFING and completely rebuild the build file.

A number of people have used a Motorola Atrix Lapdock to add a screen and keyboard with trackpad to RasPi, in essence building a RasPi-based laptop computer. Lapdock is a very clever idea: you plug your Atrix smart phone into Lapdock and it gives you an 11.6" 1366 x 768 HDMI monitor with speakers, a keyboard with trackpad, two USB ports, and a large enough battery for roughly 5 hours of use. The smart phone acts as a motherboard with "good enough" performance. The advantage over a separate laptop or desktop computer is that you have one computing device so you don"t need to transfer files between your phone and your desk/laptop.

Unfortunately for Motorola, Lapdock was not successful (probably because of its US$500 list price) and Motorola discontinued it and sold remaining stock at deep discounts, with many units selling for US$50-100. This makes it a very attractive way to add a modest size HDMI screen to RasPi, with a keyboard/trackpad and rechargeable battery power thrown in for free.

Lapdock has two connectors that plug into an Atrix phone: a Micro HDMI D plug for carrying video and sound, and a Micro USB plug for charging the phone and connecting to the Lapdock"s internal USB hub, which talks to the Lapdock keyboard, trackpad, and two USB ports. With suitable cables and adapters, these two plugs can be connected to RasPi"s full-size HDMI connector and one of RasPi"s full-size USB A ports.

The RasPi forum has a long thread on Lapdock with many useful suggestions, photos, and links: I made a Raspberry PI Laptop. There"s also a good "blog entry at element14 with photos and suggestions of where to get cables and adapters: Raspberry Pi Laptop. TechRepublic has a tear-down article with photos of Lapdock internal components here: Cracking Open the Motorola Droid Bionic Lapdock. Paul Mano has a wealth of photos of Lapdock innards at Motorola Atrix Lapdock mod projects.

Lapdock uses the HDMI plug to tell if a phone is plugged in by seeing if the HDMI DDC/CEC ground pin is pulled low. If it"s not, Lapdock is powered off. As soon as you plug in a phone or RasPi, all the grounds short together and Lapdock powers itself on. However, it only does this if the HDMI cable actually connects the DDC/CEC ground line. Many cheap HDMI cables do not include the individual ground lines, and rely on a foil shield connected to the outer shells on both ends. Such a cable will not work with an unmodified Lapdock. There is a detailed "blog entry on the subject at element14: Raspberry Pi Lapdock HDMI cable work-around. The "blog describes a side-benefit of this feature: you can add a small power switch to Lapdock so you can leave RasPi attached all the time without draining the battery.

The Lapdock Micro USB plug is the upstream port of Lapdock"s internal USB hub, and connects to one of RasPi"s full-size USB ports. Lapdock is not USB compliant since it provides upstream power on its Vbus pin. Lapdock uses this to charge the Atrix phone. You can use this feature to power RasPi if you have a newer RasPi. The original RasPi rev 1 has 140 mA polyfuses F1 and F2 to protect the USB ports, which are too small for powering RasPi using upstream power. Newer RasPis replace F1 and F2 with zero Ohm jumpers or eliminate them entirely, which allows Lapdock to provide power. If you don"t mind modifying your original RasPi, you can add shorting jumpers over F1 and F2 or replace them with higher-current fuses.

What gets powered on depends on whether Lapdock is open or closed. If it"s open, the screen and all Lapdock USB ports are powered. If you close Lapdock, the screen and full-size USB ports are powered down, but the Micro USB still provides upstream power. This is for charging an Atrix phone. When you open or close Lapdock, the Micro USB power switches off for about a second so if your RasPi is connected it will reboot and you may have a corrupted file system. There"s discussion about this at the RasPi forum link, and someone has used a supercapacitor to work around the problem: Raspberry Pi lapdock tricks.

When you do not connect a HDMI monitor, the GPU in the PI will simply rescale (http://en.wikipedia.org/wiki/Image_scaling) anything that would have appeared on the HDMI screen to a resolution suitable for the TV standard chosen, (PAL or NTSC) and outputs it as a composite video signal.

The Broadcom BCM2835 only provides HDMI output and composite output. RGB and other signals needed by RGB, S-VIDEO or VGA connectors are however not provided, and the R-PI also isn"t designed to power an unpowered converter box.

Note that any conversion hardware that converts HDMI/DVI-D signals to VGA (or DVI-A) signals may come with either an external PSU, or expects power can be drawn from the HDMI port. In the latter case the device may initially appear to work, but there will be a problem, as the HDMI specs only provide in a maximum of 50mA (@ 5 Volt) from the HDMI port, but all of these adapters try to draw much more, up-to 500mA, in case of the R-PI there is a limit of 200mA that can be drawn safely, as 200mA is the limit for the BAT54 diode (D1) on the board. Any HDMI to VGA adapter without external PSU might work for a time, but then burn out D1, therefore Do not use HDMI converters powered by the HDMI port!

The solution is to either only use externally powered converters, or to replace D1 with a sturdier version, such as the PMEG2010AET, and to replace the power input fuse F3 with a higher rated one, as the current one is only 700mA, and the adapter may use 400mA itself. Also notice that the R-PI"s power supply also must be able to deliver the extra current.

Alternatively, it may be possible to design an expansion board that plugs into the LCD headers on the R.Pi. Here is something similar for Beagleboard:

The schematics for apples iPhone 3gs and 4g suggest they speak DSI, thus they can probably be connected directly. The older iPhones use a "Mobile Pixel Link" connection from National Semiconductor. The 3GS panel (480×320) goes as low as US $14.88, while the 4G one (960×640, possibly the LG LH350WS1-SD01, with specifications) can be had for US $17.99 or as low as US $14.28. The connectors used might be an issue, but this connector might fit. Additional circuitry might be necessary to provide the display with required 1.8V and 5.7V for operation, and an even higher voltage for the backlight.

The Raspberry Pi provides one clock lane and two data lanes on the S2 connector, as can be read from the schematics. It is currently unknown whether this is enough to drive the iPhone 4G screen, as that screen seems be driven with three data lanes in its original application.

I2C/SPI ADC can be used to interface 4 pin resistive Touch Screens, For example STMPE812A. Texas Instruments has a solution for 4 or 8 wire touchscreens using their rather cheap MSP4309.

Parallel interface displays can be found in many sizes, usually up to 7" and more. Parallel interfaces are usually 8 or 16-bits wide (sometimes 18 or 24-bit wide), plus some control-lines. The Raspberry Pi P1-connector does not contain enough GPIOs for 16-bit wide parallel displays, but this could be solved by borrowing some GPIOs from the CSI-connector or from P5 (on newer Raspberry Pis). Alternatively, some additional electronics (e.g. shift-registers or a CPLD) can be used, which could also improve the framerate or lower the CPU-load.

A parallel RGB interface up to 24 bits is available on all Raspberry Pi boards with the 40-way header (A+, B+, Pi2, Pi3, Zero) and the compute module. This interface allows to connect parallel RGB displays to the Raspberry Pi GPIO either in RGB24 (8 bits for red, green and blue) or RGB666 (6 bits per color) or RGB565 (5 bits red, 6 green and 5 blue).

This mode is accompanied by new overlays, which allow to produce an RGB signal thanks to the VGA666 (get the 666 passive VGA adapter for Raspberry-Pi B+ : code and hardware).

After two theory-loaded blog posts about handling data array-like in strings (Strings, arrays, and the less known sp(lit)str(ing) function and Strings & arrays - continued) which you are highly recommended to read before continuing here, if you haven"t already, it"s big time to see how things work in practice! We"ll use a string variable as a lookup lookup table containing data of one single wave period and add this repeatedly to a waveform component until it"s full.A few weeks ago, I wrote this article about using a text variable as an array, either an array of strings or an array of numbers, using the covx conversion function in addition for the latter, to extract single elements with the help of the spstr function. It"s a convenient and almost a "one fits all" solution for most use cases and many of the demo projects or the sample code attached to the Nextion Sunday Blog articles made use of it, sometimes even without mentioning it explicitly since it"s almost self-explaining. Then, I got a message from a reader, writing: "... Why then didn"t you use it for the combined sine / cosine lookup table in the flicker free turbo gauge project?"105 editions of the Nextion Sunday blog in a little over two years - time to look back and forth at the same time. Was all the stuff I wrote about interesting for my readers? Is it possible at all to satisfy everybody - hobbyists, makers, and professionals - at the same time? Are people (re-)using the many many HMI demo projects and code snippets? Is anybody interested in the explanation of all the underlying basics like the algorithms for calculating square roots and trigonometric functions with Nextion"s purely integer based language? Are optimized code snippets which allow to save a few milliseconds here and there helpful to other developers?Looking through the different Nextion user groups on social networks, the Nextion user forum and a few not so official but Nextion related forums can be surprising. Sometimes, Nextion newbies ask questions or have issues although the required function is well (in a condensed manner for the experienced developer, I admit) documented on the Nextion Instruction Set page, accessible through the menu of this website. On top of that, there is for sure one of my more than 100 Sunday blog articles which deals not only with that function, but goes often even beyond the usual usage of it. Apparently, I should sometimes move away from always trying to push the limits and listen to the "back to the roots!" calls by my potential readers...Do you remember the (almost) full screen sized flicker free and ultra rapid gauge we designed in June? And this without using the built-in Gauge component? If not, it"s time to read this article first, to understand today"s improvements. The June 2022 version does its job perfectly, the needle movement is quick and smooth, and other components can be added close to the outer circle without flickering since there is no background which needs constantly to be redrawn. But there was a minor and only esthetic weak point: The needle was a 1px thin line, sometimes difficult to see. Thus, already a short time after publishing, some readers contacted me and asked if there were a way to make the needle thicker, at least 2 pixels.Recently, when playing with a ESP32 based NodeMCU 32S and especially with its WiFi configuration, I did as (I guess) everybody does: I loaded an example sketch to learn more about the Wifi library. When you set up the ESP32 as an access point, creating its own wireless network, everything is pretty straightforward. You can easily hard code the Wifi name (SSID) and the password. But what about the client mode ? Perhaps one needs to use it in different environments. And then, a hard coded network name and password are definitively not the best solution. Thus, I thought, why not use a Nextion HMI for a dynamic WiFi setup functionality?
