#98550 - Cycles vary?
Responding to: Jan Waclawek's previous message
Not sure about C but I used basic once to write a program which required precision timing ie. needed to account for cycles. I tried pre-caclulating the cycles with a simulator and building it into the program, the cycles varied in my case while checking time required to execute loops. I was unable to achieve the accuracy I required in my case to this point. May have been a sloppy compiler or bug in simulator probably gets complicated. I think you can use assembly statements in a c program can't you? You could use assembly for the critical parts of your program and C for the parts of the program not dependant on time.

Just a thought, may be way off base. Others can confirm or flame!
