Using ICSPCLK and ICSPDAT as input?

[cube007]

Hello,

I'm using a PIC16F676. When trying to use the ICSPCLK and ICSPDAT as a normal input, it's not possible to read out these pins.

That is my code:

#include <16F676.h>
#device adc=8
#use delay(clock=4000000)
#fuses INTRC_IO,BANDGAPHIGH,NOPROTECT,BROWNOUT,NOMCLR,NOCPD,NOWDT,PUT
#rom 0x3ff = {0x3470}

#include "main.h"
void main() {
setup_adc(ADC_OFF);

setup_timer_1 (T1_DISABLED);

setup_comparator(FALSE);
setup_vref(FALSE);

while(1) {
output_high(PIN_C3);
delay_ms(200);
output_low(PIN_C3);
delay_ms(200);

if (input(PIN_A0))
output_high(PIN_C4);
else
output_low(PIN_C4);
}
}


Is there anything I did't noticed in the spec?

Best regrads,

Ok, now I got it.

It is necessary to init the adc ports with "setup_adc_ports(xxx)" and to disable the comparator with "setup_comparator(NC_NC)".

I prefer to set everything up manually by reading the datasheets for the PIC. However, I believe that you need to do this

setup_adc_ports(NO_ANALOGS);

Hello Mark,

actually I got the solution (please take a look at this post: <a href="http://www.pic-c.com/forum/general/posts/144517189.html" TARGET="_blank">http://www.pic-c.com/forum/general/posts/144517189.html</a>). First I tried "setup_adc_ports(NO_ANALOGS)" but this command is not supported with the CCS and the PIC16F676.
