hallo...
how do i measure the eact timing on my code using boostc?
even it have speed tester, but it dont show in time base....
and how do i measure my the time of my desired code?

set breakpoints in the debugger at the beginning and end of the code you want to evaluate.
in the debugger you can see the amount of ticks. so when you let it run from breakpoint to breakpoint you are able to see how manny ticks it took. If I don't oversee something here (

) this should be a working method to determine the exact time it takes to run that peace of code.....

A tick appears to be an oscillator cycle. If you step through a 1 cycle instruction it will increment the tick count by 4. A 4MHz xtal will give 1us instruction cycle time.

The tick count will change to values in 'kilo' after a while i.e. 10k etc. which cannot be reset to zero.

If you install BoostC within MPLab (Microchip IDE) you can use its watchdog feature measure in real time.

Doh! Did I say watchdog feature ? read that as "Stopwatch feature to measure in real time."
