WiringPi-Go

Golang wrapped version of Gordon's Arduino-like WiringPi for the Raspberry Pi

Installation

install WiringPi first

Copy/paste this to your terminal to install wiringPi and wiringPi-Go

cat <<'EOF1' > installwpi.sh

echo "Donwloading and building wiringPi"
git clone git://git.drogon.net/wiringPi

cd wiringPi
git pull origin
./build

gpio -v

echo "Downloading wiringPi-Go"
go get -d github.com/CarlosRA97/wpi

echo "Finished! Let's program Raspberry Pi with Go"

Sample codes

`lcd.go`

package main

import (
    . "github.com/CarlosRA97/wpi"
)

func main() {
    WiringPiSetup()

    //use default pin naming
    PinMode(PIN_GPIO_4, OUTPUT)
    DigitalWrite(PIN_GPIO_4, LOW)
    Delay(400)
    DigitalWrite(PIN_GPIO_4, HIGH)

    //use raspberry pi board pin numbering, similiar to RPi.GPIO.setmode(RPi.GPIO.BOARD)
    Delay(400)
    DigitalWrite(BoardToPin(16), LOW)
    Delay(400)
    DigitalWrite(BoardToPin(16), HIGH)

    //use raspberry pi bcm gpio numbering, similiar to RPi.GPIO.setmode(RPi.GPIO.BCM)
    Delay(400)
    DigitalWrite(GpioToPin(23), LOW)
    Delay(400)
    DigitalWrite(GpioToPin(23), HIGH)
}

Run

export GOPATH=`pwd`
go install github.com/CarlosRA97/wpi 
go run src/lcd.go
