ST7FLITE2, it's in halt most of the time to save poer. Interrupts once a sec, but if I try and change PB3 from output to input and back the thing crashes big time. I go...
PBOR=0x00; // outputs to floating
PBDDR=0x07; //PB3 to input
PBOR=0xFF; // pullups /push pull
I put a bit of delay between each to allow the ports to settle and reverse the process to get back...I thing the micro is timing out or getting a spurious interrupt..
Any ideas.
