ifusb is a simple toolkit to access GPIO/UART/SPI/I2C from USB host through microcontroller. It was initialy attended for use with eink controller project, but can be used as a tool for any project, like a Bus Pirate board or a FT2232 chip.
Firmware use libopencm3 and has been tested with STM32F042 microcontroller. PR 663 is needed for I2C on STM32F0 https://github.com/libopencm3/libopencm3/pull/663 $ git fetch origin pull/663/head:pr-663 $ git checkout pr-663
Do not forget to edit OPENCM3_DIR in firmware/Makefine to your libopencm3 path.
Host library use libusb 1.0.
Finally, a reference design is available in hardware/ directory.
ifusb user access udev rules: SUBSYSTEM=="usb", ATTR{idVendor}=="f055", ATTR{idProduct}=="cafe", MODE="0666"
