I have developed a program for PIC16f877 in flowcode. after compiling I have dowloaded the program using MPLAB IDE. ything went sucessfully. However there is no reaction in the IC. Means it is not doing anything whatever I program. What could be the reason? Is their any other compiler can be used for downloading the program using MPLAB ICD2? Is their any way to do online debugging?
Thanks

It could be a configuration word problem. Make sure you are using configuration data that is appropriate to your hardware (e.g. clock settings). Also, turn the watchdog timer off if you are not using it.
If you are still having problems, try creating a simple LED-flasher program and get this to run before trying to solve the problem on a more complicated program.
