# Sub-$30 USB Display

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.

# Circuit

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".

# Building the Software

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.

# Running the software

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.

# License

This software is licensed under the MIT License (see `LICENSE` file).

The firmware is based on `fx2lib`, which is licensed under the LGPL (see `firmware_source/fx2lib/COPYING`).
