Hello Benj

The pic18f4685 pwm in simulation is ok,but if i compile i have error:

Hello Wolfgang,

I have had a look at the device datasheet and the FCD is slightly incorrect. There is only 1 PWM enabled pin on this device.

I have regenerated the FCD with this error omitted and your program should compile correctly now though you will be unable to use PWM channel 2 on this device.

Hello Benj

after i change the fcd file,i have the same error

Regards Wolfgang

Hello Wolfgang,

I was going to test your Flowcode file but then I noticed that you had only posted up the C code.

Are you still referring to PWM index 2 in a component macro in your program? If so then this would be enough to cause the compilation errors.

Hello Benj

I delete the 18F4685.fcd file and download new;
if i compile the code,only init > pwm(0)1 set cycle > pwm(0)1 i have the thame Error:

Hello,

Woops sorry I left a define with the PWM channels still set to 2.

Here is a working FCD that should allow you to compile correctly.

Hello Benj

Work well.
