Hello Everyone,
I was wondering where I can find some good example code of using interrupts in PBP?
What I am trying to do is have 2 push buttons one for increasing a delay and the other for decreasing the delay. When the button is pushed it will jump to the interrupt and increase/decrease the delay depending on the button. Since I will be using delays as long as 30 sec I dont want to have to hold the button the whole time waiting for the PIC to see that the button is pressed while it is in it NOP delay loop. I have the 2 buttons attached to I/O Port B line 4 and 7 on the PIC16F84. This is according to the PIC16F84 datasheet. Also, on the datasheet they talk about how the change on the I/O pin sets the RBIF flag on interrupt. With PBP do I need to worry about this?
Since I am brand new to the PIC and PBP world I really am not sure where to look for help on this.
Thanks,
MIchael
