PIC32 port interrupt problemPosted by wne on December 15, 2009 My code uses int1, int2 and int3. I set break points in each of those ISR and run my code in debug mode. When I trigger the pins, the interrupts never happen. When I stop the code, I can observe that the INTx interrupt flags were set. Any clue on what happen here? RE: PIC32 port interrupt problemPosted by Dave on December 15, 2009 Do you think this is something to do with FreeRTOS? RE: PIC32 port interrupt problemPosted by mike costa on December 15, 2009 If you never make it to the ISR, the problem is not with FreeRTOS. check your pin settings. make sure you enable GPIO interrupts for those particular pins. RE: PIC32 port interrupt problemPosted by wne on December 16, 2009 Thanks for all the answers. I am new to FreeRTOS, so, getting confused where should I look the cause. Now I fixed it. I declared: void __attribute__((interrupt(ipl1), vector(_EXTERNAL_1_VECTOR))) Membrane_Select_ISR(void) But, it does not set the interrupt priority. I have to add this IPC1bits.INT1IP = 1; then, it works. Just don't know why.
