Dear all I want to reset my controller in software.
because of some problems in my circuit.
how to do it.
I am using Winavr software
ATmega32 controller
 

have the watchdog turned off, when you want to do a reset turn on the watchdog and let it reset the microcontroller.
 

It doesn't matter if you are already using it in your project or not, use it just for resets, I don't understand the problem.

The other solution would be an external circuit triggered by the mcu in order to reset it using the reset pin.
 

I want to restart my program once intrrupt is generated and executed. then the program should start from start of main.
 

A reset and the start of main are different things, if you just want to jump to the start of main then you can use goto to jump in a label positioned in the start of main but this will not reset the mcu.

Click to expand...

Note that you shouldn't use goto inside the interrupt, instead you should just set a flag variable and then detect the value it has in the while loop (inside main) and jump to the position you want.
