usb2sun5
--------

Convert USB keyboard and mouse capable of USB Boot Protocol to Sun Microsystems Type 5 keyboard
and mouse (actually Mouse Systems 5-Byte) protocol using Raspberry Pi Pico microcontroller.

This README is WIP!


Build:
    $ mkdir build
    $ cd build
    $ cmake .. # Yes, cmake... blame Raspbery Pi Pico SDK

Flash:
    Just copy the usb2sun5.uf2 file or use openocd to flash the ELF file:
    $ openocd -f interface/cmsis-dap.cfg -f target/rp2040.cfg -c \
      "adapter speed 5000; program usb2sun5.elf verify reset exit"

Questions no one asked:
    Q: But what about the hardware?
    A: Check the usb2sun5_schematic.pdf. I'll probably write more about it later.
