FSD can clone the text content of other displays. These texts can be fixed or could be generated by other scripts (like Automatic LCDs 2 by MMaster or Isy"s Inventory Manager)

If the block has more than one display surface and you want to clone from a different screen than from surface 0, then you can add the display number directly after the colon.

LCD Panel, clone:0 position(100,50) fontsize=0.5 TextColor(255,128,0)This would clone the text contend of the first screen of the block "LCD Panel" to the position (x=100 y=50) in an orange color with a font size of 0.5.

This way you can ether reduce the number of LCD Panels needed or greatly enhance the amount of information you can display with a given set of screens/panels.

Caution: There has to be no space between "layoutrate" and the equals sign "="This will set the rate of changes for the screen layouts. (in changes per minute)

You can overide individual LCD/Cockpit screen settings by using a special keyword line starting with "FSD options:" in the Custom Data field of the Programmable block itself.

All keywords for this override options must be in a single line and this line must be located above an optional "ShowStats" line or else the used keywords affect only the LCD panels of the Programmable block.

For anyone curious following this. You can still use traditional LCD panels and the WriteText() method for your updating displays in dedicated servers.

Joined my friend"s game hosted by him. Non-dedicated server. I made a blueprint with a couple scripts loaded in, tested that everything worked in single player, but when we used it in multiplayer only the host could see the scripts update. The text doesn"t get sent to clients. It updates every detail of a panel but not the text. All LCDs, cockpit LCDs, programmable block LCDs, etc don"t update. Opening the panel shows there is no text but the host confirmed the panel is not blank and is updating for him.

Can confirm this bug. This bug seems to apply to both DS and Non-DS and the problem only happens for the connected clients, not the host (Networking issue?). The screen is updated for the host but not the client until the client reconnects where the current displayed image/text will be refreshed and stay that way until you reconnect again. Using "IMyTextSurface.GetText()" will return the correct text that is supposed to be displayed.

It seems that the programmer block has a new bug, not important but PB screen cannot be set to anything, it stays on the "No Content" image event with simple text or image or script (ex: digital / analog clock).

But it will decrease the performance of the game - you need to have powerful GPU for that, as each screen is essentially another frame to render. Thus if your FPS is 40, with another camera-on-screen it might drop to 20 (if low FPS was caused by taxed GPU, not overloaded CPU). And it will incur some cost in CPU performance.

But it can be managed: in graphic settings there might be another slider: maximum of camera-to-screens, max distance of player to screen with screens nearer to player taking preference, plus if screen is LOD model it should be ignored.

Duke Nukem 3d had a camera view to screen feature in a game with user generated maps/layouts 22 years ago. Granted it wasn"t 1080p but I don"t think anyones expecting that from a Text panel. Unpossible!

glad to see this thread bumped i find it ridiculous that this isn"t already in the game. Surely you could implement this with some sort of anti-rastorization method where you just don"t render the parts of the ship eclipsed by the display just like if you gave dirt or whatever a transparent texture back in minceraft, that"s how rodina does it; and even without the fact that this method would be way more efficient, you would also end up with a better, more spacey, implementation "cause it would have perspective.

Also, it"s not a matter of C# vs C++. It might be marginally faster if implemented correctly in C++, but it"s more a matter of the graphics card having to render 2 "screens" instead of 1.

Old mod was great, as long as you didn"t have dozens of screens running. IIRC there was a "performance" slider to make it more user friendly to lower spec machines. If you could at least consider it Keen, that would be great!

Rendering performance impact could be made O(1) by updating a set amount of screens per frame at a preset resolution. I.e. A surveillance room with 10 camera feeds would update every screen at 6 FPS instead of 60, as in this example surveillance camera clip: https://www.youtube.com/watch?v=X2oNWHv0zSQ

(Effective frame rate of the three cameras would then be 10 FPS. Camera feeds should only update when the player is actually standing in front of and looking in their direction. Screens being "freshly" activated would take the next slot in the update queue for a max 1 frame delay, unless several screens activated in the same frame.)

It is possible, but that was never a simple mod; that entry on the Steam workshop was just to add the terminal controls, the actual code was in a plugin (Client Extender) that you had to install alongside the game.It allowed you to write frames to textures and had a priority queue system so it would never drain your FPS more than you allowed it, and you could give client-side priority to cameras; if you"re in a big battle with a bunch of different people who also use LCD feeds then, from your perspective, yours would be updated first and fastest regardless.

I saw Camera, LCD, then it was obvious I could link a camera feed to one of cockpit LCD to have a view..... even at low resolution, and even with limitation numbers.

In short, as many people out there, I really believe that this should"ve been in the vanilla game since the LCD"s were introduced and also believe that it would elevate the game play so much.

Having the ability to view a camera image from an LCD in a basement - which is what I nearly always end up building in order to protect my gear from meteorites - would be a massive boon.

Also, displaying multiple camera images on LCDs means that a ship could have a decent bridge buried deep inside it and still have good visibility of the surrounding space, without needing to cycle through cameras while sitting in a control seat.

A few other suggestions would be to resize the screen if adjacent displays share a tag, an option of linking it to a remote grid would be useful too for situational awareness of your current position while controlling a remote vessel.

The mod is smart about it and makes it so that the LCD can "share" frames instead. So it can update at 30 fps but it doubles the GPU Render Load, or all the way down to 1fps which divides evenly amongst other LCDs. So if you had the setting at 30fps they"d each run at 15fps, which would divide further as you added more.

I don"t know the limitations of this engine, but that what we ask for here, is used in many games like Portel or Prey (the old one) and is used, when some NPCs are in a monitor. For example, in Half Life 2, when Wallace Breen has his speeches on the monitors, the actual NPC is loaded in a separate room on the map, where the NPC gets recorded by a virtual camerajand is streamed directly to the ingame TVs and monitors, the player can see and they do it that way, because, according to the devs, tihs is much easier then make a actual video clip to play back on the screens. So it schouldn"t be wichcraft to make something like that. Except the engine really can"t cope with that.

The Mods we had, are more or less a collection of workarounds to make this feature somewhat functioning, but someone with unrestricted access to the source code, should be able to implement, at least the frame work, for such a function, without all too heavy performance impacts. Furthermore we are in an age, of ridiculously powerfull GPU like the Nvidia 30 Series and Space Engineers never was a casual game, requirement wise. And for those with a too weak system, we could make a tab in the world settings to disable this feature.

i would make lcd refresh rate based on distance to closest player, that is looking at that lcd - so game would crank up lcd fps only when someone is actually looking at it and "freeze" display when nobody is around or looking on something else ....

I also find it very strange that this is so hard to implement... Duke Nukem 3D dynamically rendered security cameras onto display screens just fine 25 years ago (before even basic 3d graphics cards were even in most gamer"s PCs) along with a few N64 games, like Goldeneye. Not to mention more recent games like Half Life 2. There are a lot of ways to keep it performant on modern systems. Here"s a few suggestions that little old me can think of to keep system performance from being too negatively impacted.

If a remote camera LCD isn"t in visible range to a player, then don"t gather render data from the camera nor render the camera onto the LCD. I do not believe this is something that a modder could do, since it would require access to a player"s rendering data and being able to detect if any remote camera LCDs are within what"s being rendered.

Any camera feeds are sampled at a lower resolution and also rendered to LCDs at a lower resolution than when a player views through the camera directly. With a lower resolution on both sampling and rendering I would expect GPU stress to be lower as well.

Nested camera LCDs (any LCD"s rendering a camera that are THEN viewed by a later camera and rendered to a later LCD) would be only rendered at 1fps and only when the player is looking at the later LCD, otherwise it is not rendered. Or just don"t render nested camera LCDs at all, though that might confuse some players if done without explanation.

Many games implement in-view screens of the game world. This isn"t new and not impossible just something Keen chose not to implement with their time. Other priorities. The LCD displays in the game and the cameras seem like a perfect match.

You could even have lower frame rate, or have fram rate being dependent on distance to closes player so screens further away only update 10-20 fps and close by screens at higher rate.

Cool idea but one feature at a time. Once we get (if we do, at all) camera footage on a screen, we can then consider the possibility of a multi-screen set up.

The troll face says it all. PC gamers also have low end hardware. There is a bit of psychology at work here though. If your PC can"t handle the camera-to-LCD feature you may chose to turn it off for now, maybe consider a GPU or RAM upgrade or just accept it for now. For cool screenshots you can always turn it back on temporarily. You feel like it"s all in your hands. On a console on the other hand, graphics and complexity are often locked down, like the number of planets or asteroids. You can"t upgrade a hardware component or decide for yourself if camera-to-LCD is worth the performance hit. Others decide what your console can handle. You begin to feel disenfranchised compared to a PC gamer with comparable hardware.

As can be seen in this YouTube Video (https://www.youtube.com/watch?v=cWpFZbjtSQg) implementing a camera feed to the LCD screens shouldn"t be thatdifficult. Now one difference would be the need to dynamically alter the position of the projection but even as an inexperienced programmer that is not an issue. If the devs have some competence (which I would assume given they developed this game) it should not be a problem to implement at all, except of course the issue with consoles other users mentioned. Drawing a second camera is expensive for the render engine but if not done at full resolution, unless the player is accessing the camera directly, I fail to see any issues except poor performance on low end pc"s and console, which imo is already the case so that would be a drop of water in an ocean.

I do understand that this is not an easy thing to do, I still want it, but I have the programmer training to know you are basically adding a player for each camera feeding to an LCD, (For other programmers I know this is a vast over simplification but not everyone has the knowledge we do) VRage chokes enough at 12 players much less the higher numbers some servers can represent if it is add there would also need to be a server setting toggle to disable it or some troll can crash the server by setting up a dozen or two Camera/LCD pairs.

The difference is you can most likely get away with less frame rate and much less resolution and if you interleave different screens you can have multiple screens taking the performance of a single normal player or less.

The various LCD Panel blocks are a great way to add a human touch to a ship or base by displaying useful images or text. For LCD configuration and usage, see LCD Surface Options.

Note: Some functional blocks, such as Cockpits, Programmable Blocks, Custom Turret Controllers, and Button Panels, have customizable LCD surfaces built in that work the same way as LCD Panel blocks, which are also discussed in detail under LCD Surface Options.

LCD Panels need to be built on a powered grid to work. Without power, they display an "Offline" text. While powered without having a text, image, or script set up, they display "Online".

LCD Panel blocks come in a variety of sizes from tiny to huge (see list below) and are available for large and small grid sizes. Note that LCD Panel blocks all have connections on their backs, and very few also on a second side.

All LCD Panels and LCD surfaces work with the same principle: They are capable of displaying dynamic scripts, or few inbuilt static images accompanied by editable text. Access the ship"s Control Panel Screen to configure LCD Panels or LCD surfaces; or face the LCD Panel block and press "K".

A Text Panel, despite its name, can also display images. On large grid, it is rectangular and does not fully cover the side of a 1x1x1 block. On small grid it is 1x1x1, the smallest possible LCD block in game.

On large grid, you choose the Text Panel when you need something that has rectangular dimensions that make it look like a wall-mounted TV or computer screen. If you want to display images, this one works best with the built-in posters whose names end in "H" or "V" (for horizontal or vertical rotation). On Small grid, you place these tiny display surfaces so you can see them well while seated in a cockpit or control seat, to create a custom display array of flight and status information around you.

Corner LCDs are much smaller display panels that typically hold a few lines of text. They don"t cover the block you place them on and are best suited as signage for doors, passages, or containers. They are less suitable for displaying images, even though it"s possible. If you enable the "Keep aspect ratio" option, the image will take up less than a third of the available space.

These huge Sci-Fi LCD Panels come in sizes of 5x5, 5x3, and 3x3 blocks, and can be built on large grids only. These panels are only available to build if you purchase the "Sparks of the Future" pack DLC.

They work the same as all other LCD Panels, the only difference is that they are very large. In the scenario that comes with the free "Sparks of the Future" update, they are used prominently as advertisement boards on an asteroid station.

This LCD panel can be built on large and small grids. The transparent LCD is basically a 1x1x1 framed window that displays images and text. It is part of the paid "Decorative Blocks Pack #2" DLC.

What is special about them is that if you set the background color to black, this panel becomes a transparent window with a built-in display. In contrast to other LCD Panels it has no solid backside, which makes it ideal to construct transparent cockpit HUDs, or simply as cosmetic decoration.

While configuring an LCD Panel, the GUI covers up the display in-world and you can"t see how the text or images comes out. In the UI Options, you can lower the UI Background opacity to be translucent, so you can watch what you are doing more easily.

The Serial Monitor is a convenient way to view data from an Arduino, but what if you want to make your project portable and view sensor values without access to a computer? Liquid crystal displays (LCDs) are excellent for displaying a string of words or sensor data.

This guide will help you in getting your 16×2 character LCD up and running, as well as other character LCDs (such as 16×4, 16×1, 20×4, etc.) that use Hitachi’s LCD controller chip, the HD44780.

When activated by an electric current, these liquid crystals become opaque, blocking the backlight that is located behind the screen. As a result, that area will be darker than the rest. By activating the liquid crystal layer in specific pixels, characters can be generated.

As the name suggests, these LCDs are ideal for displaying only characters. A 16×2 character LCD, for example, can display 32 ASCII characters across two rows.

If you look closely, you can see tiny rectangles for each character on the screen as well as the pixels that make up a character. Each of these rectangles is a grid of 5×8 pixels.

Character LCDs are available in a variety of sizes and colors, including 16×1, 16×4, 20×4, white text on a blue background, black text on a green background, and many more.

One advantage of using any of these displays in your project is that they are “swappable,” meaning that you can easily replace them with another LCD of a different size or color. Your code will need to be tweaked slightly, but the wiring will remain the same!

Before we get into the hookup and example code, let’s check out the pinout. A standard character LCD has 16 pins (except for an RGB LCD, which has 18 pins).

Vo (LCD Contrast) pin controls the contrast of the LCD. Using a simple voltage divider network and a potentiometer, we can make precise contrast adjustments.

RS (Register Select) pin is used to separate the commands (such as setting the cursor to a specific location, clearing the screen, etc.) from the data. The RS pin is set to LOW when sending commands to the LCD and HIGH when sending data.

R/W (Read/Write) pin allows you to read data from or write data to the LCD. Since the LCD is only used as an output device, this pin is typically held low. This forces the LCD into WRITE mode.

E (Enable) pin is used to enable the display. When this pin is set to LOW, the LCD ignores activity on the R/W, RS, and data bus lines; when it is set to HIGH, the LCD processes the incoming data.

The LCD has two separate power connections: one for the LCD (pins 1 and 2) and one for the LCD backlight (pins 15 and 16). Connect LCD pins 1 and 16 to GND and 2 and 15 to 5V.

Depending on the manufacturer, some LCDs include a current-limiting resistor for the backlight. It is located on the back of the LCD, close to pin 15. If your LCD does not contain this resistor or if you are unsure whether it does, you must add one between 5V and pin 15. It should be safe to use a 220 ohm resistor, although a value this high may make the backlight slightly dim. For better results, check the datasheet for the maximum backlight current and choose an appropriate resistor value.

Let’s connect a potentiometer to the display. This is necessary to fine-tune the contrast of the display for best visibility. Connect one side of the 10K potentiometer to 5V and the other to Ground, and connect the middle of the pot (wiper) to LCD pin 3.

That’s all. Now, turn on the Arduino. You will see the backlight light up. As you turn the potentiometer knob, you will see the first row of rectangles appear. If you have made it this far, Congratulations! Your LCD is functioning properly.

We know that data is sent to the LCD via eight data pins. However, HD44780-based LCDs are designed so that we can communicate with them using only four data pins (in 4-bit mode) rather than eight (in 8-bit mode). This helps us save 4 I/O pins!

The sketch begins by including the LiquidCrystal library. This library comes with the Arduino IDE and allows you to control Hitachi HD44780 driver-based LCD displays.

Next, an object of the LiquidCrystal class is created by passing as parameters the pin numbers to which the LCD’s RS, EN, and four data pins are connected.

In the setup, two functions are called. The first function is begin(). It is used to initialize the interface to the LCD screen and to specify the dimensions (columns and rows) of the display. If you’re using a 16×2 character LCD, you should pass 16 and 2; if you’re using a 20×4 LCD, you should pass 20 and 4.

In the loop, the print() function is used to print “Hello world!” to the LCD. Please remember to use quotation marks " " around the text. There is no need for quotation marks when printing numbers or variables.

The function setCursor() is then called to move the cursor to the second row. The cursor position specifies where you want the new text to appear on the LCD. It is assumed that the upper left corner is col=0 and row=0.

There are many useful functions you can use with LiquidCrystal Object. Some of them are listed below:lcd.home() function positions the cursor in the upper-left of the LCD without clearing the display.

lcd.scrollDisplayRight() function scrolls the contents of the display one space to the right. If you want the text to scroll continuously, you have to use this function inside a for loop.

lcd.scrollDisplayLeft() function scrolls the contents of the display one space to the left. Similar to the above function, use this inside a for loop for continuous scrolling.

lcd.display() function turns on the LCD display, after it’s been turned off with noDisplay(). This will restore the text (and cursor) that was on the display.

The CGROM stores the font that appears on a character LCD. When you instruct a character LCD to display the letter ‘A’, it needs to know which dots to turn on so that we see an ‘A’. This data is stored in the CGROM.

CGRAM is an additional memory for storing user-defined characters. This RAM is limited to 64 bytes. Therefore, for a 5×8 pixel LCD, only 8 user-defined characters can be stored in CGRAM, whereas for a 5×10 pixel LCD, only 4 can be stored.

After including the library and creating the LCD object, custom character arrays are defined. The array consists of 8 bytes, with each byte representing a row in a 5×8 matrix.

The use of liquid crystal displays (LCDs) in user interface assemblies is widespread across nearly all industries, locations, and operating environments. Over the last 20 years, the cost of LCD displays has significantly dropped, allowing for this technology to be incorporated into many of the everyday devices we rely on.

The odds are high you are reading this blog post on a laptop or tablet, and it’s likely the actual screen uses LCD technology to render the image onto a low-profile pane of glass. Reach into your pocket. Yes, that smartphone likely uses LCD technology for the screen. As you enter your car, does your dashboard come alive with a complex user interface? What about the menu at your favorite local drive-thru restaurant? These are some everyday examples of the widespread use of LCD technology.

But did you know that the U.S. military is using LCD displays to improve the ability of our warfighters to interact with their equipment? In hospitals around the world, lifesaving medical devices are monitored and controlled by an LCD touchscreen interface. Maritime GPS and navigation systems provide real-time location, heading, and speed information to captains while on the high seas. It’s clear that people’s lives depend on these devices operating in a range of environments.

As the use of LCDs continues to expand, and larger screen sizes become even less expensive, one inherent flaw of LCDs remains: LCD pixels behave poorly at low temperatures. For some applications, LCD displays will not operate whatsoever at low temperatures. This is important because for mil-aero applications, outdoor consumer products, automobiles, or anywhere the temperature is below freezing, the LCD crystal’s performance will begin to deteriorate. If the LCD display exhibits poor color viewing, sluggish resolution, or even worse, permanently damaged pixels, this will limit the ability to use LCD technologies in frigid environments. To address this, there are several design measures that can be explored to minimize the impact of low temperatures on LCDs.

Most LCD displays utilize pixels known as TFT (Thin-Film-Transistor) Color Liquid Crystals, which are the backbone to the billions of LCD screens in use today. Since the individual pixels utilize a fluid-like crystal material as the ambient temperature is reduced, this fluid will become more viscous compromising performance. For many LCD displays, temperatures below 0°C represent the point where performance degrades.

Have you tried to use your smartphone while skiing or ice fishing? What about those of you living in the northern latitudes - have you accidently left your phone in your car overnight where the temperatures drop well below freezing? You may have noticed a sluggish screen response, poor contrast with certain colors, or even worse permanent damage to your screen. While this is normal, it’s certainly a nuisance. As a design engineer, the goal is to select an LCD technology that offers the best performance at the desired temperature range. If your LCD display is required to operate at temperatures below freezing, review the manufacturer’s data sheets for both the operating and storage temperature ranges. Listed below are two different off-the-shelf LCD displays, each with different temperature ratings. It should be noted that there are limited options for off-the-shelf displays with resilience to extreme low temperatures.

For many military applications, in order to comply with the various mil standards a product must be rated for -30°C operational temperature and -51°C storage temperature. The question remains: how can you operate an LCD display at -30°C if the product is only rated for -20°C operating temperature? The answer is to use a heat source to raise the display temperature to an acceptable range. If there is an adjacent motor or another device that generates heat, this alone may be enough to warm the display. If not, a dedicated low-profile heater is an excellent option to consider.

Made of an etched layer of steel and enveloped in an electrically insulating material, a flat flexible polyimide heater is an excellent option where space and power are limited. These devices behave as resistive heaters and can operate off a wide range of voltages all the way up to 120V. These heaters can also function with both AC and DC power sources. Their heat output is typically characterized by watts per unit area and must be sized to the product specifications. These heaters can also be affixed with a pressure sensitive adhesive on the rear, allowing them to be “glued” to any surface. The flying leads off the heater can be further customized to support any type of custom interconnect. A full-service manufacturing partner like Epec can help develop a custom solution for any LCD application that requires a custom low-profile heater.

With no thermal mass to dissipate the heat, polyimide heaters can reach temperatures in excess of 100°C in less than a few minutes of operation. Incorporating a heater by itself is not enough to manage the low temperature effects on an LCD display. What if the heater is improperly sized and damages the LCD display? What happens if the heater remains on too long and damages other components in your system? Just like the thermostat in your home, it’s important to incorporate a real-temp temperature sensing feedback loop to control the on/off function of the heater.

Another important consideration when selecting a temperature sensor is how to mount the individual sensors onto the display. Most LCD displays are designed with a sheet metal backer that serves as an ideal surface to mount the temperature sensors. There are several types of thermally conductive epoxies that provide a robust and cost-effective way to affix the delicate items onto the display. Since there are several types of epoxies to choose from, it’s important to use a compound with the appropriate working life and cure time.

For example, if you are kitting 20 LCD displays and the working life of the thermal epoxy is 8 minutes, you may find yourself struggling to complete the project before the epoxy begins to harden.

Before building any type of prototype LCD heater assembly, it’s important to carefully study the heat transfer of the system. Heat will be generated by the flexible polyimide heater and then will transfer to the LCD display and other parts of the system. Although heat will radiate, convect, and be conducted away from the heater, the primary type of heat transfer will be through conduction. This is important because if your heater is touching a large heat sink (ex. aluminum chassis), this will impact the ability of the heater to warm your LCD display as heat will be drawn toward the heat sink.

Before freezing the design (no pun intended) on any project that requires an LCD display to operate at low temperatures, it’s critical to perform low temperature first. This type of testing usually involves a thermal chamber, a way to operate the system, and a means to measure the temperature vs time. Most thermal chambers provide an access port or other means to snake wires into the chamber without compromising performance. This way, power can be supplied to the heater and display, while data can be captured from the temperature sensors.

The first objective of the low-temperature testing is to determine the actual effects of cold exposure on the LCD display itself. Does the LCD display function at cold? Are certain colors more impacted by the cold than others? How sluggish is the screen? Does the LCD display performance improve once the system is returned to ambient conditions? These are all significant and appropriate questions and nearly impossible to answer without actual testing.

As LCD displays continue to be a critical part of our society, their use will become even more widespread. Costs will continue to decrease with larger and larger screens being launched into production every year. This means there will be more applications that require their operation in extreme environments, including the low-temperature regions of the world. By incorporating design measures to mitigate the effects of cold on LCD displays, they can be used virtually anywhere. But this doesn’t come easy. Engineers must understand the design limitations and ways to address the overarching design challenges.

A full-service manufacturing partner like Epec offers a high-value solution to be able to design, develop, and manufacture systems that push the limits of off-the-shelf hardware like LCD displays. This fact helps lower the effective program cost and decreases the time to market for any high-risk development project.
