On an RPi 1 I managed to read the gpio pins as normal user by executing
the following script, which starts pd at the end.

	#!/bin/bash

	# set the TX RX pins to become inputs as well
	gpio -g mode 14 in
	gpio -g mode 15 in

	# set the following pins to low by default
	gpio -g mode 4 down
	gpio -g mode 5 down
	gpio -g mode 0 down
	gpio -g mode 6 down

	gpio -g mode 15 down
	gpio -g mode 8 down
	gpio -g mode 7 down
	gpio -g mode 1 down

	# export the pins to be read by a normal user
	# This numbering is already by BCM_GPIO number
	gpio export 2 in
	gpio export 3 in
	gpio export 4 in
	gpio export 17 in
	gpio export 27 in
	gpio export 22 in
	gpio export 10 in
	gpio export 9 in
	gpio export 11 in
	gpio export 0 in
	gpio export 5 in
	gpio export 6 in
	gpio export 13 in
	gpio export 19 in
	gpio export 26 in

	gpio export 14 in
	gpio export 15 in
	gpio export 18 in
	gpio export 23 in
	gpio export 24 in
	gpio export 25 in
	gpio export 8 in
	gpio export 7 in
	gpio export 1 in
	gpio export 12 in
	gpio export 16 in
	gpio export 20 in
	gpio export 21 in

	pd -rt gpioReading-demo.pd
