can i give 230 volts sine wave directly to the RB0 pin of pic16f877a with high resistor in series to to know the zero crossing point on the sine wave form. what will be the code for that?
pic16f877a
Please help me to develop a code in PIC16F877A for zero crossing detection in a sine wave from supply. I/P sine wave has to be directly fed to the B0 interrupt pin.
