18F4620 HPWM Half Bridge Mod problem

[showtime]

Hi Bruce , Thank you for interest.

The problem is not simulation. I have just tried your code on the proto board. It is not working. I programmed your code. Nothing was changed.

Did you use some fuse setting that i didn't see in your code. I think something is wrong with this PIC model because my 18F458 and 16f690 and 16f684 is working Half bridge Mod properly in ISIS and proto board.

Thank you again.

Here's the config settings I used when running this through MPSIM.

__CONFIG _CONFIG1H, _OSC_HS_1H
__CONFIG _CONFIG2H, _WDT_ON_2H & _WDTPS_512_2H
__CONFIG _CONFIG3H, _PBADEN_OFF_3H
__CONFIG _CONFIG4L, _LVP_OFF_4L & _XINST_OFF_4L

I have attached the .hex & .bas files I used.

After looking at one of many errata sheets for the 18F4620, I doubt I'll be in
any huge hurry to try this one.

The Rev A silicon Errata sheet shows a boat-load of problems with the ECCP
module. It could very well be a silicon bug. Good luck...;o}

Thank you very much for valuable helps. The last code was the same. I will research more. Maybe one mounth later i will work with other PIC wich have not got big bugs if I can't succeed.

Best regards.

18F458 is working very well with the same code but 18F4620 is not. I think there is a PIC bug.
