LED Blinking With Explore M3 Revision as of 14:54, 24 April 2016 by Explorer (Talk | contribs) (diff) ← Older revision | Latest revision (diff) | Newer revision → (diff)

In this tutorial we will see how to blink the LED using the explore Embedded bare metal libraries.
Please check the below link for detailed explanation on LPC1768 GPIO's configuration.
LPC1768 GPIO Configuration

Project Setup

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

Similar to arduino the LED is connected to pin number 13.

Code

Below is the sample code the blink the LED connected at 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
	}
	}
