[SOLVED] Sine wave inverter with pic16f72 and if2110

[tommy212]

@siktec i tried it it is not working please help use out

adamhenry, I don't understand, the problem was with the schematic or with the code?

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

 

[kabeer02]

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.

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

am using pickit2 and still not working

 

[naseerak]

Don,t use code protect option to avoid verification errors

 

[tommy212]

@naseerak i did not use code protection

- - - Updated - - -

i think the code is been protected

 

[Fidelis Anyanti]

simple Pickit2 clones will not program some pics.

 

[tommy212]

which one do you think i can use

 

[siktec]

Hi everyone, If anybody has the LCD connection diagram pls help me us with it.

 

[Fidelis Anyanti]

This is the lcd connection.

 

[tommy212]

@Fidelis Anyanti please is the pic 16f72 or 16f73

 

[Fidelis Anyanti]

The schematic is for pic16f73

 

[tommy212]

which means the sine wave is for pic16f73

 

[naseerak]

This is the LCD wiring scheme.

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?
