Hi,
Am working on SAM E70 Xplained Development Borad, and I have enables external interrupt on the push button switch with ISR in "main.c" file and the program is working good.
Now when i moved the External interrupt handler to a ".h" header file, the program compiles without any error, but interrupts are not getting triggered.
Any idea like the interrupts are not getting triggered?
Why would you use a pushbutton on an interrupt and why would you put code in a .h file?
I think you'll have to show us the code so we can see what you are doing.
Harikrishnan911 Hi Kartman,
I used push button because it is easy for me to test its working using SAME70 Xplained development board.
I tried moving most of the function to header files because I wanted the main.c to look as simple as possible.
The program is in my working machine & i might need some time to export it from that PC to this one that has got internet.
Move your code to other .c file. Never put code in .h files.
Harikrishnan911 Definitions are written in .c file. Only the declaration in present in .h file.
no need to defineinterrupt functions. They are already defined by ASF
Harikrishnan911 I could see default ISRs for timers, usarts, etc.
But for ext. int. we need to define the ISR
Harikrishnan911 Maybe its something that I doesn't know.
Am not an expert in ASF & atmel Studio
Harikrishnan911 Got the issue resolved,
since I have moved the ISR to header files, it seems like the control jumps straight to the default ISR defined by ASF rather than navigating to the ISR defined in the header files.
This issues was resolved by associating the location of these ISR to main & with that minor modification, everything seems to be working in good order.
