LED ON program - a practice exercise using WiringPi and GPIO pins
// ELEC 494 Mechx DK LED GPIO Intro//Program: LEDgpio1.c#include <stdio.h>#include <wiringPi.h>// Need wiringPi.h include file for specific instructions for GPIOintmain(){ int i; wiringPiSetup(); // Sets up the I/O pins and instructions for wiringPi // Attach my LED and its resistor (diagram is provided // in your Fritzing wiring Diagram //Use GPIO 0 pin 11 to turn on and off LED // Set up my GPIO connector pin 11 to be an OUTPUT pinMode(0,OUTPUT); digitalWrite(0,HIGH); //Turn ON GPIO to 3.3V or HIGH voltage for(i=1;i<1000; ++i) { //waiting or delay function } digitalWrite(0,LOW); // Turn OFF LED delay(2000); // delay 2000 ms digitalWrite(0,HIGH); delay(5000); // delay by 5000 ms digitalWrite(0,LOW); printf("\n\n I'm done! All pau! \n\n");}Wednesday, February 3, 2016
