LED Blinking With Explore M3
Revision as of 13:55, 28 April 2016 by Explorer (Talk | contribs)

In this tutorial we will see how to blink the LED using the explore Embedded bare metal libraries.
The libraries can be used on different platforms like Keil, ARM GCC, GCC And Eclipse etc.
Please refer Project Setup Section for setting up the platforms.


Prerequisites

Please check the below link for detailed explanation on LPC1768 GPIO Configuration.
If you are doing it for the first time, then check the below links to setup the project for generating the .bin file.

  1. Keil4 Setup
  2. Keil5 Setup
  3. ARM GCC Setup
  4. Eclipse & ARM GCC Setup

Hardware Connection

ExploreM3 comes with on board led connected to pin 13.


Code

Below is the sample code the blink the LED connected to pin 13.

#include "delay.h"
#include "gpio.h"
#include "stdutils.h"
#define LED 13 //LED is connected to pin 13 on Explore M3 board
int main()
{
SystemInit(); //Clock and PLL configuration
GPIO_PinFunction(LED,PINFUN_GPIO); // Configure Pin for Gpio
GPIO_PinDirection(LED,OUTPUT); // Configure the pin as OUTPUT
while(1)
{
GPIO_PinWrite(LED,HIGH); // Turn ON the Led
DELAY_ms(100); // Wait for some time
GPIO_PinWrite(LED,LOW); // Turn OFF the Led
DELAY_ms(100); // Wait for some time
}
}
