i soldered my pic16f877a ic in board,first 2 ic s were burned out ,finally i soldered 3rd one .its working but the voltage i got from the tx pin is 3v.the input to the pic is 5v.
my questions are
1) do we have to give 2 vdd and vss in PIC ?if i do what happens?
2) how to check the correct working of oscillator and capacitors.
3) why its showing 3v in tx pin ?
4) how to check max232 ic?
