Joyboot
This is a bootloader for the Palawan joystick project. It can update Palawan boards over USB or wireless.
Hardware
Joyboot runs on Palawan hardware, both on the Tx board and on the Rx USB board. As such, it includes a bit-banged USB stack.
The source for the hardware may be downloaded at https://github.com/xobs/palawan-hw
Software
The software is still in flux. It will have an accompanying PC program to control the hardware, however this program is still being written.
