The aim of this project is to get the 320.240.36 working with the RaspberryPi. This display doesn’t have a controller, means it need timings signals and pixel data 4 by 4. First working solution was to use a SED1335 compatible controller, such as the RAIO8835. But even using the GPIO of the Rpi, data transfer rate is too low to get video and no half tone. Second option was to use a FPGA as custom controller. TI makes a DVI to parallel chip, the TFP401 http://www.ti.com/product/tfp401a. Then the DVI output of the raspberry can be directly used. Here the Terasic Development board DE0-Nano made around and Altera Cyclone IV is used as timing generator for the EL display, and process the data coming from the TFP401.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
