increase buffer ?? #20

Closed shift838 closed 3 years ago

shift838 commented 3 years ago

is there a way to increase the buffered characters amount? When I use this on one of my Retro computers and if I type something before the program is completely up or before any process is finished; say, "12345" when the program comes up or the process is finished I will only get the first 2-3 characters first typed.

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

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.
