#182637 - irq pin Responding to: ???'s previous message |
when i'm testing such irq, i'm using transistor , 'pulsed' by RS232 connector of PC, controlled by some simple programm.
But here is no problem with button for testing, problem is handling - especially for beginner. Probably You should make things complicated - for example - in pin ISR disable EX0 , enable it again in main loop after 'post-processing' is done. Post here ISR only - see button "Inser Program Code" above. I do not understand how You are testing Your software - in some simulator , or in siliscon on board? EA signal is floating? regards |
