Interrupts and Script Conundrums

[Jon236]

2 Problems I am seeking wisdom on:

Utilizing interrupts 3 & 4. It appears that they are both accessed through PORTB. Can one use them independently of one another? I can't see how at the moment.

Scripted code. Using CMD_TURN, the state variable never gets to 'STOPPED', so rc remains at 0 and it loops endlessly. We are using code from the 1-22 version without alteration. Anyone deal with this yet successfully?

Hope the upcoming snow doesn't shut down our shop again!!!! You Canadians love the stuff!!

take a look at the interrupt code in InterruptHandlerLow() in user_routines_fast.c in Kevin Watson's code at http://kevin.org/frc/edu_interrupts.zip what you have to do is look at the difference between the last PORTB value and the current
