This version does not have touchscreen attached It"s exactly the same TFT display as PID 1596 but without the resistive touch panel so it is a little less expensive.

This is a "raw pixel-dot-clock" display and does not have an SPI/parallel type controller or any kind of RAM. The display is supposed to be constantly refreshed, at 60Hz, with a pixel clock, V sync, H sync, etc. There are some high end processors such as that used in the BeagleBone that can natively support such RGB TTL displays. However, it is extremely rare for a small microcontroller to support it, as you need dedicated hardware or a very fast processor such as an FPGA. Not only that, but the backlight requires a constant-current mode boost converter that can go as high as 24V instead of our other small displays that can run the backlight off of 5V

For that reason, we are carrying it as a companion to the Adafruit RA8875 driver board in the store, which is a chip that can handle the huge video RAM and timing requirements, all in the background. That"s the best way to interface this display to just about any microcontroller (including Arduino & friends) If you want to control with from an HDMI or DVI output, check out our TFP401 driver board. If you are an advanced electronics enthusiast you can try wiring this directly to your processor, but it we don"t have any support or tutorials for that purpose.

Have you gazed longingly at large TFT displays - you know what I"m talking about here, 4", 5" or 7" TFTs with up to 800x480 pixels. Then you look at your Arduino. You love your Arduino (you really do!) but there"s no way it can control a display like that, one that requires 60Hz refresh and 4 MHz pixel clocking. Heck, it doesn"t even have enough pins. I suppose you could move to ARM core processors with TTL display drivers built in but you"ve already got all these shields working and anyways you like small micros you"ve got.

What if I told you there was a driver chip that could fulfill those longings? A chip that can control up 800x480 displays, and heck, a resistive touchscreen as well. All you need to give up is 5 or so SPI pins. Would you even believe me? Well, sit down because this product may shock you.

The RA8875 is a powerful TFT driver chip. It is a perfect match for any chip that wants to draw on a big TFT screen but doesn"t quite have the oomph (whether it be hardware or speed). Inside is 768KB of RAM, so it can buffer the display (and depending on the screen size also have double overlaying). The interface is SPI with a very basic register read/write method of communication (no strange and convoluted packets). The chip has a range of hardware-accelerated shapes such as lines, rectangles, triangles, ellipses, built in and round-rects. There is also a built in English/European font set (see the datasheet section 7-4-1 for the font table) This makes it possible to draw fast even over SPI.

The RA8875 can also handle standard 4-wire resistive touchscreens over the same SPI interface to save you pins. There"s an IRQ pin that you can use to help manage touch interrupts. The touchscreen handler isn"t the most precise driver we"ve used, so we broke out the X/Y pins soyou can connect them up to something like the STMPE610 which is a very classy touchscreen controller.

On the PCB we have the main chip, level shifting so you can use safely with 3-5V logic. There is also a 3V regulator to provide clean power to the chip and the display. For the backlight, we put a constant-current booster that can provide 25mA or 50mA at up to 24V. The connector to the screen is a classic "40 pin" connector. All the 40-pin TFT"s in the Adafruit shop are known to work well. There are other 40-pin displays that have different pinouts or backlight management and these may not work - they may even damage the driver or TFT if the boost converter pushes 24V into the display logic pins! For that reason, we only recommend the displays we"ve tested and sell here.

Each order comes with an assembled, tested RA8875 breakout and a stick of header. You"ll also need to purchase a 40-pin TFT screen. We currently have 4.3" and 5.0" screens available.

To get you started we"ve written a graphics library that handles the basic interfacing, drawing and reading functions.Download the Adafruit RA8875 library from githubandinstall as described in our tutorial.Connect a 40 pin TFT to the FPC port and wire up the SPI interface to an Arduino as described in the example code. Once started you"ll be able to see the graphic/text demo and then touch the screen to "paint". For more advanced details on what the RA8875 can do (and it can do a lot) check the datasheet.

It might help if I give more scope for my application. My current project runs on a PIC32MX 80MHz,output is to a320x 240 TFT, coded in C and using Mikro C and their closed TFT library. The code is over 5,000 lines and has the following IC2 sensors, light, BME280 (humidity, temp, pressure), DS3231 RTC, also connected is a GPS read by a UART, user control is via rotary encoder and center push switch. The user selects one of 7 top level menu/screens and the display then updates for the selection, this requires most of the display to update. The display can be set to show updating graphs for temp, humidity and pressure for last 24 hours and 7 days. The problem is there is now too much data to show on a 320 x 240 screen, it really needs a larger screen with higher resolution, the PIC32 with Mikro TFT library is on it"s limit updating the current screen so a faster CPU with better TFT libraries is needed or make a big change and move to a Rpi. The actual screen updates are not that fast after each screen is initially redrawn, I have limited updates to only parts of the screen to keep flicker/updates less noticeable. The only constant screen updating is the time being shown in larger type font at the top of the screen and this changes only once /sec.

So for the question of preferred library and or screen, I should have really asked what Teensy 3.6 libraries are available for any controller type suitable to drive a 5" TFT display at 800 x 400?

Looking on Adafruits webpage they have the RA8875 Driver Board for 40-pin TFT Touch Displays - 800x480 Max and a library available which might work with the Teensy, then add their 5.0" 40-pin TFT Display - 800x480 with Touchscreen. But it would be good to know if alternative Displays exist that have been tested and any better libraries written to drive them, that work with Teensy. I don"t have the coding skills to write my own Libraries or modify existing ones as I only started coding in C last year.

This is a little display for the Raspberry Pi, It features a 2.8" display with 320x240 16-bit color pixels. This version has a capacitive touchscreen, you can now use your fingers.

The plate uses the high speed SPI interface on the Pi and can use the mini display as a console, X window port, displaying images or video etc. Best of all it plugs right in on top!

This design fits onto the Pi Model A+, B+, or Pi 2! Works just like the Model B version, but now matches the outline of the Raspberry Pi 2 and Model B+. It also has all 40 pins GPIO pins brought out so you can connect a 40-pin GPIO cable underneath.

The display and touchscreen uses the hardware SPI pins (SCK, MOSI, MISO, CE0, CE1) as well as GPIO #25 and #24. All other GPIO are unused, there"s 4 spots for optional slim tactile switches wired to four GPIOs, that you can use if you want to make a basic user interface.

Use it for console access or easily pop up X11 onto the PiTFT for a mini monitor, although its rather small at 320x240. Instead, we recommend using PyGame or other SDL-drawing programs to write onto the frame buffer.

For these LCD"s the XG4200 uses a CPLD based LCD Hardware Accelerator. This hardware accelerator is based on the XG5000 CPLD technology and includes 256k or 1MByte dedicated LCD memory (depends on LCD type). The Rabbit 4000 can access the LCD memory via its I/O interface without extra waitstates. The Hardware Acceleration is used for drawing graphic primitives (X-Graph DynamicC library) and supports 64k colors on all LCD"s.

For the 5.6" LCD (contact us for availability) uses the Rabbit 4000 innovative build-in DMA controller. Combined with a fast SRAM chip and X-Graph knowledge this allows the LCD refresh logic and Rabbit memory access to coexist without the need for a wait line or waitstates. This results in fast graphical LCD performance for graphic LCD"s with a size up to QVGA in max. 8 bit/pixel mode.

By using a set of optimized assembly graphic functions, graphic primitives can be drawn directly in the video memory map. This without a noticable build-up delay. The processor has full read/write access to any memory location in the video memory without the need for waistates.
