Firmware for an ATSAMD21E18A that acts as a USB Host, expecting a keyboard supporting the HID boot protocol to be connected. It outputs debug information to a serial port (TX=PA10, RX=PA11).
I intend to add SPI transmission, similar to emu_keyboard_mcu, so this can be wired up to the emulated_keyboard hardware, allowing me to connect a USB keyboard to my BBC Master motherboard. Eventually I'll make a single PCB that does all of this.
- Install the latest Arduino IDE, and the "MattairTech SAM M0+ Boards" package (see the "SAM M0+ Core Installation" section in the MT-D21E rev B user guide.
- At the command line, run "make build".
- If you have a J-Link, at the command line, run "make program". Otherwise program the board with your favourite SWD programmer.
