I have a pb with my .c

[WalkOver]

Hello to all Flowcode users !

I have a problem with my .c when I use a pwm macro. Please, look what I get:

Code: Select all

Yet I use a peak 18F2620 which can generate pwm.
I tried checking the box "use alternative pin" but it does not solve the problem.
How can I correct this?

Thanks in advance.

Hello WalkOver

This C code is correct. The part at the top is simply to check that there is indeed a valid PWM pin. Have you tried compiling your code. DOes it compile and run correctly?

[WalkOver]

Yes, compilation ends successfully, but the simulation with the software Proteus Isis and my .hex doesn't work. I don't have the equipment to check the proper functioning of the PIC yet, but I think that the problem must come from Proteus.

Thanks for your prompt response

PS : Sorry for ma bad english
