but i don't have anyother interrupts setup for the same time as the external interrupt? But if your "main" code happens to be doing a printf when the interrupt occurs,... should i first come out of the isr, then setup the serial port? Yes, that's the general idea. Generally, an ISR should do the absolute minimum necessary to clear the interrupt, and inform the "main" code. The "main" code would then do all the processing, displaying, etc. eg, see http://www.8052.com/forum/read.phtml?id=82231 |
