Multiple PWM outputs

[Mark]

I downloaded their demo and got the same error. I changed the device type to an 18F458 and the code compiles. Are you using the demo or a full version?

[davt]

I am using the full version.
I tried changing the chip as you did but same result!

[Mark]

Are you sure that you have the PCH compiler? I believe the full version is called PCWH and not PCW.

[Mark]

Also, make sure the dropdown at the top says "Microchip PIC18" and not "Microchip 14 bit"

[davt]

According to the manual - quote " PCW is the professional package that includes both the PCM and PCB compilers ".

I tried a test project and selected the device - 18f252 but up pops a message saying it cannot find 18f252.h - I do not seem to have CCS's header file although the chip is listed!

[davt]

I have only 2 options - Microchip 12 bit / Microchip 14 bit - strange?

More expense!!!!

Mark, nice code!

Is there anything special to use the #org directive?

I always get "Invalid ORG range" at the end of main.c

Thank you.

Mark:

I'm using the 18f458, compiler 3.212.

When I try to use the #ORG 0x08 it shows the error.

Copy/pasting your handlers for example at the top of my code and below the mcu's definition doesnt work.

I dont know if there's something different to do when org'ing to an already used code section. Maybe it is conflicting with the complier dispatcher.
I searched your code for something that would disable the default dispatcher but found nothing.

[Mark]

I did not use any of the CCS int handlers and you cannot with that code. It handles both the high and low priority interrupts and saves only the scratch data that those interrupt handlers use.

[future]

Done, made my dispatcher insite ext1 fast, testing both ext1 and timer2 flags. Timer2 is configured as High priority in main().

[Mark]

So are you saying that you are using the CCS int handlers. You declared ext1 as "Fast" and manually setup Timer2 to use high priority. Then you added a test inside of ext1 interrupt for timer2? Or are you saying that you created you own dispatcher and the code executes very quickly (fast)?
