AVR-Chat

Thanks for looking Jim,

I only show a small section of code... like I said: I know interrupts work 
because a timer interrupt works.

I just found an appnote that says I should read both SPDR and SPSR to "Clear 
SPI Interrupt Flag by reading SPSR and SPDR" before sei.
I don't think I did that... I thought SPIF in SPSR is clear to start with, 
and would get cleared again as it enters the ISR...
And I didn't think I need to read the data buffer (SPDR) to make interrupts 
work...

I might try tomorrow.

Thanks,

Cat

Just the obvious: I don't see a global interrupt enable!
