hxPiGpio

Haxe/OpenFL extension for using the GPIO Ports on the Rapberry Pi

Status: Deprecated.

WiringPi is no longer maintained, so unfortunately this means the end of this this extension

Requires wiringPi 2.29 to be installed.
Not all methods in WiringPi are exposed!

Installation

cd into a directory where you store haxe modules that are not in the haxelib repo

git clone https://github.com/gepatto/hxPiGpio.git
haxelib dev hxPiGpio hxPiGpio/
cd hxPiGpio
lime rebuild . rpi -clean

example usage

add the following to your openfl project.xml
<haxelib name="hxPiGpio" />

read a digital input

PiGpio.wiringPiSetupGpio();
PiGpio.pinMode( 18, PiGpio.INPUT ); // 18 is gpio18
var pinValue = PiGpio.digitalRead(18);
trace(pinValue);

Requirements

make a file called /etc/udev/rules.d/20-gpio.rules with the following file contents

SUBSYSTEM=="bcm2835-gpiomem", KERNEL=="gpiomem", GROUP="gpio", MODE="0660" SUBSYSTEM=="gpio", KERNEL=="gpiochip*", ACTION=="add", PROGRAM="/bin/sh -c 'chown root:gpio /sys/class/gpio/export /sys/class/gpio/unexport ; chmod 220 /sys/class/gpio/export /sys/class/gpio/unexport'" SUBSYSTEM=="gpio", KERNEL=="gpio*", ACTION=="add", PROGRAM="/bin/sh -c 'chown root:gpio /sys%p/active_low /sys%p/direction /sys%p/edge /sys%p/value ; chmod 660 /sys%p/active_low /sys%p/direction /sys%p/edge /sys%p/value'"

add the following environment variable:

export WIRINGPI_GPIOMEM=1
