Using kbd.c within a INT_TIMER1 routine
PostPosted: Tue Jul 29, 2003 1:47 am     Reply with quote
As I have not yet tried this but will in the next day or so I'd thought to try the forum...

I presume that the KBD.C routine is useable within a INT_TIMER1 service routine. To be implemented on a F877 device running at 20MHz with a timer interrupt every 20mS.

If anyone has any good ideas or thoughts, I'd be happy to hear them else i'll let you know how it went.

ISR's should be as short as possible. It is best to set a flag in the ISR and then check the flag in the main loop.
