Dear all,
To communicate pc to atmega32 I googled and reached max232 circuit. The problem is in some schematics pin2 of max232 connected to gnd via cap but some connect it to vcc via cap also for pin 6 schematics are not the same. Following some schematics on the web I connected pin 2 of max232 to +ve of a cap and -ve of that cap to gnd. And pin6 to -ve of another cap and +ve of that cap to gnd. When I switch power on l7805 and this max232 got hot. So I decide to get solution from the forum please help. Snap shot of different schematic attached
