CCP1 as PWM - configuration?!?!?

[andypak]

Hi to all,
I have a configuration problem on CCP1 (PIC18F4620). I'd like use this as PWM and so I have used the following instruction:
setup_ccp1 (CCP_PWM);

but CCS compiler 4.017 give the following error:

*** Error 102 "D:\Progetti PIC\PHACO\ligiSource\t-mainm.c" Line 1579(23,24): Expect comma

so I have wrote
setup_ccp1 (CCP_PWM,CCP_PWM_H_H);
but the PWM is always OFF. Before use this CCS version I used another version that now I don't remember and with this old version I haven't any errors.

after this instruction I have put these others:
setup_timer_2 (T2_DIV_BY_1, 255, 1);
set_pwm1_duty (50);

Which is the correct instruction?

First, do a search 'back' about V4 versions. Unfortunately, the 'sticky' thread that existed for a couple of years athe top of this forum, has now gone, but V4.017, is unlikely to work.
Basically, you can reckon that anything before the late 4.030 releases, _will_ have major issues...

On your chip, V4, adds the options to configure the ECCP features. However these are meant to be 'optional', with the ECCP module being 'reverse compatible' with the normal CCP. Unfortunately, your compiler is not correctly handling this. On a more modern compiler, the standard syntax is accepted, and works. You have two choices:

1) Write the required control bytes directly to the registers yourself, and hope that none of the other bugs with this compiler version jump out later....
2) Update the compiler.

Best Wishes

Ok, thank you, I'll try to buy another version.
