| [SOLVED] CCP2SEL VIA APFCON1 on PIC16f1825 not working |

Hello. I'm using PCM Compiler V4.140. I'm very simply just trying to get CCP2 (PWM2 specifically) to work on PIN A5 instead of PIN C3.
I'm using the code below and it *still* makes PWM2 work on C3, even though I'm trying to set it to work with A5.
| Code: |
#include <16f1825.h>
#use delay(clock=32000000, int)
#byte APFCON1 = getenv("SFR:APFCON1")
#bit CCP2SEL = APFCON1.0
void main ()
{
CCP2SEL = 1;
setup_timer_2(T2_DIV_BY_1,255,1);
setup_ccp2(CCP_PWM);
set_pwm2_duty(500);
while(1)
{
}
}

you should dump and post the listing and see what bits are being set, it could be a compiler bug.
the listing is the 'projectname.lst' file ...

The following program was tested with CCS vs. 4.140 and it works.
Comment out the appropriate line to switch the PWM output to pin C3 or A5.
| Code: | #include <16F1825.h>
#fuses INTRC_IO, NOWDT, BROWNOUT
#use delay(clock=32M)
//==============================
void main ()
{
setup_timer_2(T2_DIV_BY_1, 255, 1);
//setup_ccp2(CCP_PWM | CCP2_C3);
setup_ccp2(CCP_PWM | CCP2_A5);
set_pwm2_duty(128);
while(TRUE);
} |

This worked for me, thank you!! |
