I only use CCS C compiler and as far as I know no MPLAB. Programs are loaded via CCSload.

The problem was that I included file x and made the changes to file y....
So the file which is included ne ...

Edit: I need to go to bed.....
The .h file I changed was one of my older program I saved the .h file with a new version number but my program still included the old one.

Well, just reinstalled ...

Jay, I did change the program as you described. I'm programming the PIC via CCSload and a ICD-U64.

@PCM, will give it a try.

More strange things happen. I changed the oscillator from HS to INTRC but in the LST file nothing changes after compiling and rebuilding the project.
The time stamp at the top of the LST file does ch ...

Ttelmah, were can I find the information you showed? I found it under "C/ ASM List" which gives me a *.lst file. But your code layout seems different then mine.

I have replaced the debug ...

Just missed your answer Ttelmah. My previous comment has more or less be answered by your comment.

About the timings. For my application the timing is not precise. The controller may hang for a few ...

Thanks for your answer. I was under the assumption that "SETUP_WDT(WDT_ON)" at the begin of the main was sufficient.
Got that out of the following link: http://www.ccsinfo.com/forum/viewtop ...

I'm having some problems with the watchdog in my program. This is the first time I want to use a watchdog. Occasionally my controller stalls due to voltage spikes caused by switching an inductive load ...

Sometimes a break is all you need....

IOCON1 = 0xC400; // PENH and PENL controlled by PWM module
IOCON1 = 0xC400; // PENH and PENL controlled by PWM module

Of course this need ...

You are right, with the help of those functions it is much easier to understand what is happening.
But it was good to have tried it directly by writing registers as Mike described. It has learned m ...

Many thanks to both of you!

I now have PWM1 working on a frequency of 26kHz and I'm able to change the PWM frequency during my program. So the begin is there.
The functions Ttelmah gave work quite ...

I'm experimenting with writing registers but I'm not sure if I write the registers correctly.

On page 144 of the datasheet the power supply register map is given. I want to write into the PTCON reg ...

I appreciate your help, thanks for that!
I will read the manual and datasheet and see how things will go. Will get back here with the results within a few days.

Mike,

For example: _bif void set_pwm_duty(unsigned int8 module, unsigned int16 duty);
This is mentioned in the 30f2020.h file.
I can't find anything about phase so I may assume that there is no ...
