Pic12f683 only has digital out on pin 2 (GP5) - microcontroller

Question

I've been trying to get started with the PIC12f683 in order to get familiar with the PIC family of microcontrollers.
I've got it hooked up to a Pickit 3, and talking to my PC, that all seems to work fine.
I've been trying various LED flasher examples from the internet but no matter which example code I try, or what I do with the TRISO or GPIO registers, I only get output on pin 2, none of the other GPIO pins will do anything.
Electrically speaking... Pins 1, 4, 6, 7, and 8 are connected to the Pickit for ICSP. Pins 2, 3, 5, and 7 have LEDs with 220 ohm resistors going from the pin to ground, and pins 1 and 8 are connected to a lithium ion battery (~3.7 v).
This is the code I am using currently.
#define _XTAL_FREQ 8000000
#include <xc.h>
// BEGIN CONFIG
// CONFIG
#pragma config FOSC = INTOSCIO // Oscillator Selection bits (INTOSCIO oscillator: I/O function on RA4/OSC2/CLKOUT pin, I/O function on RA5/OSC1/CLKIN)
#pragma config WDTE = OFF // Watchdog Timer Enable bit (WDT disabled)
#pragma config PWRTE = OFF // Power-up Timer Enable bit (PWRT disabled)
#pragma config MCLRE = OFF // MCLR Pin Function Select bit (MCLR pin function is digital input, MCLR internally tied to VDD)
#pragma config CP = OFF // Code Protection bit (Program memory code protection is disabled)
#pragma config CPD = OFF // Data Code Protection bit (Data memory code protection is disabled)
#pragma config BOREN = OFF // Brown Out Detect (BOR disabled)
#pragma config IESO = OFF // Internal External Switchover bit (Internal External Switchover mode is disabled)
#pragma config FCMEN = OFF // Fail-Safe Clock Monitor Enabled bit (Fail-Safe Clock Monitor is disabled)
//END CONFIG
int main()
{
TRISIO =0b00000000; //RB0 as Output PIN
GPIO = 0b00111111;
while(1)
{
GP5=1;
GP4=1;
GP0=1;
GP2=1;
__delay_ms(1000);
GP5=0;
GP4=0;
GP0=0;
GP2=0;
__delay_ms(1000);
}
return 0;
}
I believe the config portion was generated by MPlab, the rest is copied/modified from this instructable:
https://www.instructables.com/id/How-to-Blink-an-Led-With-PIC16F886-/
but the results are the same no matter what example code I use. I'm guessing there's a register or configuration variable I've set wrong somewhere, but I can't figure it out.

Answer 1

You had to switch your Outputs to digital.
int main()
{
TRISIO =0b00000000; //RB0 as Output PIN
ANSEL = 0; // all outputs digital !!!!!
CMCON0 = 0b00000111; //turn Cin Pins as I/O
GPIO = 0b00111111;
while(1)
{
GP5=1;
GP4=1;
GP0=1;
GP2=1;
__delay_ms(1000);
GP5=0;
GP4=0;
GP0=0;
GP2=0;
__delay_ms(1000);
}
return 0;
}
The outputs GP0 ... GP4 are default analog ones.
And please remember GP3 share the pin with MCLR, so it is an input only pin.
