12F683 2 x PWM Outputs

[Darrel Taylor]

I think I had it pointing to PBPW at the time.
Proteus saves the compiler path in the .dsn file.

Go to ... Source > Add/Remove Source code files..
Change the "Code Generation Tool" drop-down box so it points to your installation. (PBPMPLAB)

Nope same error

Can you post exactly whats in your source code boxes?

[Darrel Taylor]

Here's the way that one was setup. But you should change it to use COF instead of HEX and add the -K# command line option.
And make sure your compiler setup is working with a new design.

Thanks working now.

I've upgraded to a 16F88 chip now.

Just a thought, is it possible for SSPWM to use TMR0 instead of TMR1 on the 16F88 bearing in mind my 2khz
PWM requirement with variable 10-90% duty in 1% steps?

I'm not complaining SSPWM works well but freeing up TMR1 would let me use it for my
speedo routine.

[Darrel Taylor]

Well, you could certainly write a program that uses TMR0 to generate frequencies.
But SSPWM will not do it.

It needs a 16-bit timer to meet the published Frequency/Dutycycle range.
