It took me much less time than expected to be able to interact with the OMEGA board:
Before testing my USB to keyboard adapter board, I had tested the reception of codes from the USB keyboard. So I knew it was working. But I still didn't know how MSX BIOS scans the matrix keyboard.
After a few attempts and oscilloscope tests, I was able to send 'things' to OMEGA. But obviously not the right codes. After having researched the official codes of the MSX keyboards, I realized that the BIOS installed on OMEGA manages the Japanese keyboard! Why not!...
My first goal being to be able to type a little Basic program and run it, I decided to code the essential characters. First, the alphabet:
For now, the coding is more of the quick and dirty type but it works very well!
