increase buffer ?? about ps2keyadvanced HOT 3 CLOSED

This may well be another delay in your application not processing keys quick enough.

However you can try changing in PS2KeyCode.h the definition for

#define _RX_BUFFER_SIZE  8

to

#define _RX_BUFFER_SIZE  16

from ps2keyadvanced.

I did see that line in the library and changed it to 16 and even 32, but had no effect.

This suggests not reading keyboard quick enough which even for manual keypresses is a very long time in instruction cycles that suggests other things holding up your application.
