Re: keypad and mega64

2004-04-15 by chrisatwan2000

I get no response from any key being pressed.  I tested the same 
code on a at90s8515 and stk500, and it worked fine.  I realize that 
on the mega64 you need AVcc connected (it is), M103 = 1 (it is), and 
you can't directly write to PORTF and PORTG (I think I have that 
right, PORTG is working fine).  I have code if you would be 
interested in checking it out?
