Thanks! Very helpful Smile

P.S. the 5000 ms and 3000 ms delays I had in the code were for debugging, so that I have enough time to read the adc conversion values that are output on port_c. I intend on removing them in my final ...

Thanks for the replies. I guess it makes sense to not have delays inside an isr. But the 5 ms delay I have, because right after the LO-HI edge of the clock signal, there is a 5 ms rise time in the out ...

Hi. I wrote the following code to use a signal from a 1-axis compass. I'm using interrupts to sample the compass signal upon a Lo-Hi edge of a clock signal (also from the compass). Here is the code:
...

Thanks a lot! The interrupt is working now. I really appreciate all your help Smile

You connnect the trigger to one of external interrupt pins (INT0..INT2), define an interrupt handler #INT_EXT in CCS C and enable it by enable_interrupts() and ext_int_edge().

Thanks again for the ...

I think, the problem can be handled by connecting the event signal to an external interrupt rather than a clock input.

To achieve a delay, the interrupt can start a timer and the timer interupt the ...

Hi,

I am trying to use an external clock input in my PIC18F2525. I want to use either the hi-2-lo or lo-2-hi edge of this clock pulse to trigger a portion of code that would sample for an a/d conve ...

Hi,

I need to sample an analog signal on channel 0 of PIC18F4220. My problem is that i need to take 104 samples, and each of them needs to be spaced exactly 192 microseconds apart. This is for a fr ...
