Slowly getting it together on the Pic demo program. I've retyped the
source and have this:-

#include <stdio.h>
#include <stdlib.h>
#include <xc.h>
#include <pic12f1840.h>
#define INT_OSC 500000L
#define _XTAL_FREQ _INT_OSC
/* 12.0 page 101 setup the ports
*/
TRISAbits.TRISA0 = 0;
TRISAbits.TRISA1 = 0;
TRISAbits.TRISA2 = 1;
/* DISABLE ANALOG FEATURES */
ANSELAbits.ANS0 = 0;
ANSELAbits.ANS1 = 0;
ANSELAbits.ANS2 = 0;
/* page 107 enable weak pullup on A2 */
WPUAbits.WPUA2 = 1;
OPTION_REGbits.nWPUEN = 0;
uint8_t random_byte = 0xB4;
void dorand(void)
{
asm("BCF STATUS,0");
asm("RRF _random_byte,W");
asm("BTFSC STATUS,0");
asm("XORLW 0xB4");
asm("MOVWF _random_byte");
}
int main(int argc, char** argv) {
while (1) {
// Wait for button to press (go low)
while (PORTAbits.RA2) {};
// toss the coin
dorand();
// set the lights
if (random_byte & 0x01) {
PORTAbits.RA0 = 1;
PORTAbits.RA1 = 0;
} else {
PORTAbits.RA0 = 0;
PORTAbits.RA1 = 1;
}
}
return (EXIT_SUCCESS);
}
