Hi, can someone help point me in the right direction. I have a simple program that takes push button inputs and then sends them by IR led link to a receiver. It uses the printf function to drive the LED and the KBI on P0 for the p/button inputs.
The program compiles ok and the printf works if I do a printf("rtrt") just before entering the main loop where the program is supposed to sit until a KBI is detected. Problem is I cannot trigger the interrupt. Additionally, I get an L16 'unused code, ignored for . . . etc' message for the interrupt service routine. So, I think that the compiler or linker is not seeing the isr. I don't think its a hardware issue. I've checked wiring and voltage level changes on the P0 pins.
Any thoughts on this?
thanks
Jason
