Thanks.
Yeah OLED of this size and resolution would be great. If not much more expensive.
@Gouty, from other topic.
I think my controller should work with mechanical keyboards too. One should disable my code for anti ghosting. The only possible issue is that I don’t have NKRO implemented.
I simply send changed key to USB when matrix changes (after debounce and anti-ghost code). I scan keys matrix at 960 Hz (and whenever key state changes I send it already, during scan).
I simply assumed that nobody will press 1000 keys a second. Or just so many that it would get stuck or something. I never had any issue so far. Not sure if it would change with mechanical keyboards, theoretically one could press a lot more keys at once. For ghosting matrix it’s difficult to hold more than 8 (even 3 can ghost already).
