This project aims to control a small 320x240 TFT display module over USB using a Cypress EZ-USB FX2LP development board.
It is a proof of concept right now.
For an overview of the 40-pin display module pinout, see: http://www.rinkydinkelectronics.com/files/UTFT_Requirements.pdf
My display module has an SSD1289 controller and is marked "TFT_320QVT".

PD6 -> 13 (DB14)
PD7 -> 14 (DB15)
To rebuild the firmware, you will need a Linux system with sdcc and make installed. Run make in the firmware_source directory to generate a new firmware.ihx file in the build directory.
To get it to compile on Arch Linux, I had to change the type signature of putchar and getchar in fx2lib/include/serial.h to the following:
To build the host software, you can use go build on Windows.
Run fx2-usb-display.exe <x> <y>, where x and y are the top left corner of a 320x240 pixel screen area that will be copied to the display.
