16f873 10 bits adc

[Calamar]

Could someone help me?
I cant get 10 bits resolution, the next code
give me a error when I try compile it:

PRINTF FORMAT TYPE IS INVALID,



#include <16f873.h>
#use delay (clock=4000000)
#fuses NOPROTECT, XT, NOWDT, PUT, NOLVP, BROWNOUT
#use rs232(baud=19200, xmit=PIN_C6, rcv=PIN_C7 )
byte seconds=0;
byte count=15;
byte mem=0;

#int_rtcc

clock_isr() {

if(count--==0) {
++seconds;
count=15;
}
}

main() {
setup_adc_ports ( RA0_ANALOG );
setup_adc ( ADC_CLOCK_INTERNAL );
set_adc_channel(0);


set_rtcc(0);

setup_counters (RTCC_INTERNAL, RTCC_DIV_256);
enable_interrupts (INT_RTCC);
enable_interrupts(GLOBAL);
do {
if(seconds!=mem) {
printf ("\n\r \%lu",read_adc());
mem=seconds;
}

} while(1);
}

Add the following line, after the include file.
#DEVICE ADC=10

This switches the compiler to returning a 10 bit value. Without this, 'read_adc' will return an 8 bit value.
This is in the manual entry for the read_adc function.

Best Wishes
