Re: [AVR-Chat] disable SPI? Mega162

2010-08-09 by Jeff Blaine

John,

Never mind it.  I made a stupid mistake on the #define - had the wrong blasted pin.  

Thanks - our suggestion was not the answer - but it helped push my head to the answer and I'm most grateful for it.

John,

Sorry, I don't quite follow your meaning????

do you mean the pins on the SPI port are always dedicated to the SPI function? 

Or, is it that even when SPI is enabled, you can always directly write to those pins and affect their state (until an SPI operation reverses them, that is...)?

Thanks!

The SPI, all pins, is ALWAYS available regardless.
