Count clock cycles?
PostPosted: Sat Jan 13, 2007 1:00 pm     Reply with quote
How can I count clock cycles of part of my code? I'm using Mplab+CCS. I need just part, not all code. Some suggestions??

Thanks

Use the StopWatch in MPLAB to do this.

It's in the MPLAB Debugger menu and it works with the MPLAB Simulator.
You have to set the processor clock speed in the Debugger/Settings menu.
You can measure the number of instruction cycles between two breakpoints.
In the MPLAB Help menu (Debuggers/MPLAB SIM) , look for the section
on "Using the Stopwatch".
