How can we generate PORT1 interrupt for using mspgcc?
Hello I am having the confusion regarding to generate PORT1 interrupt.
I have attached the code below.When it compiles it gives the error like:
....................................
> "make.exe" all
msp430-gcc -mmcu=msp430xG4619 -O2 -Wall -g -c -o on.o on.c
on.c:11: two or more data types in declaration of `PORT1_service_routine'
on.c:52:1: warning: no newline at end of file
make: *** [on.o] Error 1
> Process Exit Code: 2
> Time Taken: 00:01
............................................
So i m in trouble now. Please help me with this issue.
Regards,
Sachin
