PIC 16f72 inverter code

[syed md]

hi frnds i have an inverter pcb of pic 16f72 which is the new version... i studied the whole circuits and traced them.. but i cant complete it since i dont know to drive the gate of the mosfet.. so if any one can help me.. plz do ur favour... i need the source code...

Each pin of PIC16F72 is programed to do certain function according to requirments. How would someone guess, which board is it and what functions are there on board. You didn't provide even a schematic.

Alertlinks, i dont have the schematic of the latest version.. i have the schematic of the older version only... i will provide the pin details.
they are as follows.
Port A is all analog pins, i can manage those things.
Pin 11 - osc1
Pin 12 - osc2
which have 5v as output.
Pin 15 - ocs3
Pin 16 - osc4
Which have 2v as output.

Pin 18 - Relay
Pin 14 - buzzer
Pin 24-28 - LED's


These are the things which i have....

What you are trying to do is called reverse engineering. You have to draw schematics after studing board and then draw layout with component placement. Then study the board behavior with different inputs and evaluate the timing and wave shapes of different outputs. Evaluate working flow and block diagram the try to code the mcu.Sometimes it is easy to develope a fresh project rather than copying. From your description I think it is to drive full hbridge.

Post hi-resolution pictures of front and back of the pcb. A picture is better than a thousand words.
