Since the documentation at https://github.com/breakintoprogram/agon-docs does not have an issue tracker, I'm posting this here: Currently ZDS C is the only option mentioned for programming in C. The free Small Device c compiler (SDCC) has the ez80_z80 backend (which uses the eZ80 in Z80 mode). IMO, it would make sense to mention it in the documentation, and maybe provide a simple "Hello, world!" or such example for the AgonLight.
I find I need to press return twice on this board to input detail and the programs run really slowly. It's almost like the interrup / update is triggered by pressing return key on my Keyboard. Any ideas?
Agon is an Olimex Agon Light 2 version
UsingJUSTOP PS/2 Compatible keyboard. Lag is even worse if I use a plug in adapter. Connected to USB port on desktop / Mac is easier but the lag is still there.
