Good Evening all,
I have successfully ported the original MSP430F5438 demo built for CCSv4 into an MSP430F6638, but I am now having difficulties with the interrupt routine that comes from one of the push buttons. I have modified the routine so that it uses port P1.0 of the chip since that is where I have a button open, but as soon as the interrupt routine starts, FreeRTOS behaves strangely and does not return to the routines nor displays data on the screen. Does anyone have any idea on what could be happening here?
I find it strange that the scheduler continues to work, and if I press the interrupted button it will go back to the interrupt subroutine, but nothing happens after that.
The only changes that I made to the code was in the main.c file were I modified the interrupt vector to use port1.
Any help in this issue will be greatly appreciate it.
