As an option, you can order this TFT pre-assembled onto a breakout/carrier board. The board allows easy prototyping through its 0.1" headers. You can also include the carrier board in your end product to simplify construction and assembly.

This development kit includes everything needed to get started with the 3.5" EVE module: a 320x240 display mounted on an EVE2 graphically accelerated PCBA, a Seeeduino, an EVE breakout board, jumper wires, USB cable and a ribbon cable. We even assemble this kit and pre-load some demonstration software so that you can have a functioning module in your hands within seconds.

Because the display module includes an EVE (embedded video engine) chip, it"s a perfect choice for an HMI. EVE is a graphics controller solution that can control both display and audio operations. Additionally, Bridgetek/FTDI supports the EVE chip with graphical design toolchains to aid in development.

This kit consists of a CFAF320240F-035T a 320x240 3.5" Full Color TFT LCD module mounted on a carrier board (CFA-10074). The carrier board supports a current driver for the LED backlight of the display.

This TFT LCD display module is perfect for the designer who"s looking to have a graphic and audio processor already embedded in the display unit. Powered by an FTDI/BridgeTek FT810 Embedded Video Engine (EVE) graphics accelerator chip, simply send over a few commands via SPI or I2C and the EVE will put your stored image up on the display. Need to draw a line, create dials/knobs/buttons, or rotate an image? Send a handful of bytes and the EVE will take care of it.

Further information including programming examples, interface design software, and more can be found on FTDI’s website here: https://www.ftdichip.com/Support/Utilities.htm or on our GitHub repository.

The official Debian image of Raspbian [3] was running for the test and for the operation of the QR code player. After the image was unpacked using dd, it was transferred to a 2GB large SD card.

Make sure you have selected the correct device file for the SD card. In the example provided, this is the /dev/sdb file. The file name of the image will change once an updated file is available on the website.

After copying the image and connecting the LCD module, you should restart the mini-PC. Provided the Rasp Pi is connected to the local network, configuration can then proceed via SSH from another computer. I tested this process using a FRITZ!Box router. Immediately after installation, the Raspberry Pi became available via ssh pi@192.168.178.101.

If you use an SD card that has a capacity much larger than 2GB, it makes sense to call rasp-config and expand the filesystem (Expand Filesystem) on the entire SD card. You should update the operating system once it runs, then install the packages for developing C programs as follows:

Next, you will need the driver for the graphics controller. You should download and compile the current source code from the website of the developer [4] so you can reference the libraries in your own programs later. After downloading and unpacking, you should call three commands as follows:

Once you do this, the driver libraries will also become available for the C-Berry software. The manufacturer of the screen provides these for download [5]. As before, you should compile the code after unpacking:

Calling the test program with ./tft_test will show whether the procedure has been successful. The results will be displayed on the screen at intervals of five seconds. Additionally, the test program initializes the display and calls up the functions from the examples.c library one after the other.

The code in tft_test provides the basic procedure for programming your own applications. You should include the bcm2835.h, tft.h, and RAIO8870.h libraries and initialize the display with the TFT_init_board(), TFT_hard_reset(), and RAIO_init() functions. Then, call the functions for drawing and log out the driver with bcm2835_close().

The functions in the manufacturer"s source code provide the starting point for a new program that shows pictures on the screen. Going through the project will help you understand the basic procedures. Listing 1 illustrates how the loadbmp.c feature of the C program loads an image in bitmap format and then displays it on the screen.

Listing 2 contains the corresponding header file. The bitmap must be 320 pixels wide and 240 pixels high and have a color depth of 24 bits. The bitmap header cannot be compressed, and it cannot contain further metadata. You would need to integrate additional graphics libraries if you want to process formats that don"t follow these specifications.

To compile the code, you will still need to get the sources for the tft.c, RAIO8870.c, and bmp.c libraries, as well as the accompanying header files from the Admatec example. Next, you should compile the program with the Makefile from Listing 3. With the binary executable, you can load the bitmap file using the call:

If you don"t call the program with a file name, it will stop without any further indication. You could call the software from a script and have status reports displayed as images on the screen. Figure 3 shows the output of the bitmap file that will later serve as the splash screen for the player.

The script in Listing 4 contains a script based on ImageMagick that converts arbitrary image formats into the desired format. The conversion of image files into corresponding bitmaps occurs with the following call:

Next, the script (together with the program from Listing 1) shows the file that has been created on the screen. You can find both the code that you will need to display bitmaps from the listings as well as the script for converting image files into matching bitmaps online [6].

The problem is that it that the fb2cberry (used to copy the frame buffer from hdmi to dispplay) dose not work corectly on the Pi Zero ( the one without camera connector).

Dose anybody know how can I fix this problem? I did a lot of research on google, but didn"t find anything related. I did try the display on 2 pi zero with the same results.
