Simple question on getc()
PostPosted: Fri Apr 04, 2008 6:56 am     Reply with quote
Can an interrupt "break" a getc() while using a software "UART"?

Thanks!

I'm gonna say "yes". But if the getc() function is also used in an interrupt routine, so interrupts will be disable during execution to prevent reentrancy.
