Part Number: MSP430F169
Tool/software: Code Composer Studio
Hello everyone,
I am currently working on an existing Project using a MSP430f169. I am supposed to get the firmware running with ccs 9 and the ti compiler.
I ran into a Problem setting up an Interrupt. Whenenver I setup P2IFG=0; and then enable the interrupt I end up in the interrupt routine. I investigatet this with:
if(P2IFG){blink_led}; -> Blinks
P2IFG=0x00;
if(P2IFG){blink_led}; -> still blinks...
Port 2 interupt capability is only activated for one pin, should trigger on falling edge and the pin is set high by an external adc.
I have no idea why the interupt flag is always set, although I explicitly set it to 0.
Anyone who had a similar problem or an idea for a solution?
Greetings
