#179050 - the common method is .... Responding to: ???'s previous message |
If anyone gets any ideas on how to get any sort of rising edge/logic "high" interrupt, on any of the interrupts, please let me know
the common method is to insert an inverter between the signal and the port pin. I have, with some SILabs chips used a comparatot since it has interrupts for both going high and going low. If you choose that route beware, the comparator is a bit slow. I just had another look at your code and do not see the interrupt being enabled. Erik PS I missed that of pins 6 and 7 one was on P1 and one was on P3, sorry. |
