12F675 and pullups

[geoff99]

I used the PIC wizard to create a new project for a 12F675 (asking for the weak pullups to be enabled) and got the following source code:

#include "junk.h"
void main()
{
port_b_pullups(TRUE);
setup_adc_ports(0);
setup_adc(ADC_OFF);
setup_counters(RTCC_INTERNAL,RTCC_DIV_2);
setup_timer_1(T1_DISABLED);
setup_comparator(NC_NC_NC_NC);
setup_vref(FALSE);
}

where junk.h contains
#include <12F675.h>
#device adc=8
#use delay(clock=4000000)
#fuses INTRC, BROWNOUT

If I try and compile (using v3.168), I get an error "undefined identifier port_b_pullups". If I comment out the port_b_pullups line, it compiles fine.

Anyone know why the compiler is choking on this statement?

Also bear in mind that using port_a_pullups(TRUE) will result in only GP0 having its WPU enabled. The argument passed to port_a_pullups() should be the WPU register value you want.

Well I guess my mistake was to only consult the online help (not the manual) which has no mention of port_a_pullups. Still curious why the wizard chose port_b by default.

Thanks for the tip about the TRUE argument. I didn't quite pick up on this, but sure enough the help for port_b_pullups mentions:
"Parameters:
value is TRUE or FALSE on most parts, some parts that allow pullups to be specified on individual pins permit a 8 bit int here, one bit for each port pin."
