The above video introduces one to using Geany for Raspberry Pi and using it for programming WiriingPi an Arduino like C library to control the RPi GPIO. For more on Geany see http://www.geany.org/Main/HomePage.


WiringPi Blink an LED Demo

by Lewis Loflin

WiringPi allows one use Arduino type programming with the Raspberry Pi GPIO. Here I'll explore how this is used and how it differs from Arduino.

I'll connect Raspberry Pi to a LED which will blink.

WiringPi comes native to the newest version of Rasbian. One must be root to use.

Under root create a folder: "mkdir /root/work" and put your programs in there when being compiled.

Under Geany notice an arrow next to "Build" and open a drop down menu go down to command options or whatever. Under build in the box add "-lwiringPi" at the end.

This is written in C and has to be compiled. I suggest using Geany under Linux.

Get it "sudo apt-get install geany-plugins".

WiringPi was developed by Gordon Henderson.

#include <wiringPi.h>
#include <stdlib.h>
#include <stdio.h>

#define ledPin 25
// P0-P7 is 0-7 works through pins 29
// see pin connections

int main() {
  printf ("Raspberry Pi - blink LED \n") ;
  if (wiringPiSetup () == -1)
    exit (1) ;
  pinMode(ledPin, OUTPUT);
  while (1) {
    delay(100);
    digitalWrite(ledPin, 0);
    delay(100);
    digitalWrite(ledPin, 1);
  }

  return 0 ;
}

Raspberry Pi GPIO connections.

The above is seen on the terminal when executed from Geany.
