This is the software for Bugblat's tiny FPGA board - the tif board.
A tif board is a small USB dongle which carries a non-volatile Lattice Semiconductor MachXO2 FPGA.
To program the FPGA, you start by writing a firmware program, usually in VHDL or Verilog though there are other options. The firmware program can be simulated and compiled to a JEDEC bitstream with Lattice's free Diamond software.
Then you have to inject the bitstream into the tif's FPGA, and that's the job of the software in this repo. Primarily in Python, there are programs to
- program the onboard FPGA with a compiled bitstream
- control the FPGA firmware from a PC
Example FPGA firmware programs are also included, plus an example of controlling the FPGA from a web application.
