@tommy212, Pls, explain the nature of challenge that you have.
 

@siktec the hex code for the pic16f72 is not working each time i tried to program it,
it say error

Use 22uf as the boostrap, 1n4007 is okay

I have try it with 22uf capacitor the output voltage was not high enough but when i use 47uf i works fine,for the 1n4007 i believed is not ultra-fast switching diode and our switching freq is up to 3khz
 

@tommy212, Ensure you are using pic16f72. If the one you are using is not accepting the hex code, it may be Faulty. Get another one.
 

@siktec i tried it with 8 pic16f72 each time i tried to verify it it say error please help me out i will give u a million thanks

Which programmer,you are using?
I tried with JDM programmer and pic pgm software.
And got success.
I think issue is with your programmer.

Don,t use code protect option to avoid verification errors
 

@naseerak i did not use code protection

Hello everyone, thanks for your assistance with the LCD connecting diagram. It work perfectly, however, there is still a problem with this project. The feedback control is not working. Can someone guide me on what to do please?
