USB protocol to PS/2 protocol

somhi commented 3 years ago

Hello! I'm thinking of two projects for CH559. I've got the electrodragon CH559 dev board.

USB keyboard protocol to PS/2 protocol. Then I've already got an Arduino PS/2 to XT protocol converter. Serial to PS2 conversion could also be done in the Arduino, or everything could be done in the ch559 board.
USB keyboard and mouse connected converted to serial (atc1441 example) and in a FPGA board convert the serial to ps2 to use the already made HDL modules working with ps2 inputs.

Do you know of already made examples of these or the best approach to get there?

I've also posted this in the CH55x telegram group https://t.me/ch55x Join us there for discussion about the CH55x :) There we have Mr. kprasadvnsi who has been doing lot of work on this microcontroller https://github.com/kprasadvnsi/CH559_Doc_English

I've been working on a fork that does PS/2 - https://github.com/rasteri/HIDman
