Pluggy Keyboard Interface Specification?
Posted: 23 May 2021, 14:13
Hi there, I'm trying to bring menloparkinnovation's aforementioned FPGA core to a popular FPGA platform for retrogaming, called the MiSTer project. https://github.com/MiSTer-devel/Main_MiSTer/wiki
As part of this process, I'm trying to add keyboard support, and I'm having trouble grokking the pluggy mcplugface arduino code. Could you give me a high-level specification of "given these ps/2 scancodes -> output these hex bytes to the joyport"? I've tried putting the ps/2 scancodes through raw, and tried ascii as well. The code looks like maybe it's ascii plus a few flags? If anyone has good documentation on this I would be very appreciative.
