Hi

After running this program 10 screen 1:sprite$(0)="0HH0":fori=0to1:r=pad(12):x=(x+pad(13))and255:y=(y+pad(14))and255:put sprite 0,(x,y),8:i=-strig(1):NEXT I managed to detect pin 37 (PC6 on stm32) equivalent pin 8 on gameport state change. And it was state change only after running this co...

Stm32 doesn't directly access port lines, but via cpld, so if there was no right logic internally then I wouldn't have access to pin 8.
Terrible fire said that I should have access to pin 8 values on stm32 pin 37.
I will try to do some prof of concept this weekend.

@terriblefire

I think because how pin 8 is used we might not be able to support mouse with current CPLD firmware?

Unlikely?
This looks more like issue with one of the chips?

As of mouse support I will add this to my todo list for this firmware, I am a little bit snowed in at work just now, but winters are long in Scotland. @arkadiusz.makarenko Yes, now that we got the keyboard working, we can start talking about the mouse support. :) I did enhance the keyboard test one...

....and basic LED Support implemented. (link stays the same) I need to hold CAPS status in stm32, and I don't have way of reading current CAPSLOCK value from MSX,so I imagine it will be fairly easy to get those two values out of sync, but for standard use cases it will do the job.

I have improved on last firmware.
I still have LED control to do for CAPS LOCK.

NYYRIKKI Thank you! This is very helpful, as so far I was working blindfolded on both USB and MSX side. It is over 90 keys to guess right, this would have been more than hitting jackpot in lottery. I will combine your numpad section and most normal keys from mu guesswork, and try to match it to thi...

@NYYRIKKI I have built new firmware you can downloand it here https://github.com/arkadiuszmakarenko/TFMSX/blob/NYYRIKKI/Release/TFMSXRev2F730.bin Not good, but things changed... This seems to be a lot more difficult problem than I originally thought, but now ie. Numpad works fine! - Now you did not...
