| Turn off SCSO |

Hi There,
I'm trying to use PIN_C0 as an output but seem not to be able to do so. Looking at the datasheet, I see that it can be a SSCO or a SCKLI as well. I don't need nor want this functionality. How do I switch this off best to be able to use it as a normal ouput?
Thank you,
My little test program:
| Code: | #include <18F86K22.h>
#case
#device adc=16 HIGH_INTS=TRUE
#fuses NOWDT //Watch Dog Timer uses 1:65536 Postscale
#fuses HSH //Hi-Speed crystal oscillator
#fuses NOBROWNOUT //No brownout reset
#fuses NOPLLEN //No PLL enabled
#fuses BBSIZ1K //1K words Boot Block size
#fuses NOXINST //Extended set extension and Indexed Addressing mode disabled (Legacy mode)
#fuses PROTECT
#use delay(clock=20000000)
void main (void)
{
output_high(PIN_C0);
output_high(PIN_A4);
while(1);
} |

Have you tried the following?
#fuses SOSC_DIG

Oh Hi Fusillade,
Sorry my second post just coincided with your post.
I haven't tried #fuses SOSC_DIG yet, will do that right now!
Thanks for your reply!
Ron
I thought I might have a bad chip, got a second one but same result. My code, again:
| Code: | #include <18F86K22.h>
#case
#device adc=16 HIGH_INTS=TRUE
#fuses NOWDT //Watch Dog Timer uses 1:65536 Postscale
#fuses HSH //Hi-Speed crystal oscillator
#fuses NOBROWNOUT //No brownout reset
#fuses NOPLLEN //No PLL enabled
#fuses BBSIZ1K //1K words Boot Block size
#fuses NOXINST //Extended set extension and Indexed Addressing mode disabled (Legacy mode)
#fuses NOPROTECT
#use delay(clock=20000000)
void main (void)
{
while(1) {
output_high(PIN_C0);
output_high(PIN_A4);
delay_ms(10);
output_low(PIN_C0);
output_low(PIN_A4);
delay_ms(10);
}
} |
Result: RA4 toggles just fine but RC0 stays low all the time... how can I get that to toggle as well?
Thanks!
Ron
Help would be greatly appreciated |
