This is a C library to establish an SPI channel with hardware instantiated in an iCE40 ICEStick FPGA over an USB bridge via the FTDI FT2232H chip.
Original code written by julian1 https://github.com/julian1/ice40-spi-usb-controller based on Clifford Wolf's iceprog program from https://github.com/cliffordwolf/icestorm.git.
The code was subsequently refactored into this static library (Lib-Stick-Bridge) by Felipe Correa da Silva Sanches [email protected].
Happy Hacking!
