Yes, I did, thank you.

Be aware that your timings will still not be right, if you do something like a 'delay' statement, unless you have fixed the clock statement. Your chip is _not_ running at 3.9 ...

ckielstra, I took your timer0 rtc example in another post and I had the same problem. Then instead of using set_timer0(250) I tried set_timer0(65000) and that changed the time as it should. It still w ...

ckielstra: thank you for the note on the setup_spi.
As for the timer I tried 8 and 16 bit and I didn't correct before sending.
INTRC is what I use and I tried INTRC_IO to see if it would make a diff ...

Sorry, I forgot to mention that I run it on the real hardware and not simulation. For the sake of this problem the only relevant hardware is a darlington driving the LED.

Thanks for the prompt reply PCM.

The compiler version is CCS PCH C Compiler, Version 4.106, 49215

I did paste what was in the main.h in the main.c for simplicity.
Whatever I write in set_time ...

I am using a PIC18F23k20 and whatever I write to set_timer1(nnnn) the time between two interrupts is not changing. Looking at the .lst shows that the registers are written as expected. Changing the cl ...

Thank you PCM that was the problem.

Note that in the CCS PCH compiler (and PCB and PCM), integer data types
are 'unsigned' by default. If you want a signed value, you need to
declare it explici ...

I wrote a graphic application that run perfectly on the PIC24 using
primitive routine like the one below which is driving a line.

On the PIC18F I replaced the 'int' with 'int16'.
All my functions ...

After several emails, the last one copying the CEO of the company I received this answer on 8/3/09:

It seems there is a bug in the 24 bit RTOS even though it is our intention for it to work. I w ...

PCM in fact I should have think about that too as I have been consulting the manual. Embarassed

I did notify CCS and I am curious to see their answer.

Actually they do say it is supported in PCWHD ...

Thank you PCM I will.
It is a pity because it is working really well on the 18F. At least for this project.
Again, I'll post any news I get on this subject.

Actually they do say it is supported i ...

here is the answer from CCS:

Hey,

RTOS is not supported for PCD. Is there somewhere on our website that documents that it is? Thanks.

C ...

I did try the same program on a 18F8490 board and it works.

What could make a PIC24 reset while it doesn't with the 18F?
Is there a bug in the watch dog timer that prevent it to be disabled?
An e ...

I received a confirmation from CCS support that the processor is resetting. They are going to look into it but didn't say how long it will take.
I am going to try with an 18F8490 to see if I have the ...

Sorry, I forgot to remove that line. I was trying different things in my desperation and forgot to remove the line before posting.
I did ask CCS tech support and hope to get an answer today. If I do ...
