步骤从C / C ++程序进行LED闪烁？ [英] Steps to make a LED blink from a C/C++ program?

问题描述

什么是做一个小电路从C / C ++程序LED闪光灯？最简单的步骤

What are the easiest steps to make a small circuit with an LED flash from a C/C++ program?

我想preFER所需的依赖和包数最少的。

I would prefer the least number of dependencies and packages needed.

• 什么端口将我连接到的东西？


• 哪些编译器怎么用？


• 如何将数据发送到该端口？


• 请我需要有一个微型处理器？如果不是我不想用一个这个简单的项目。

编辑：感兴趣的任何操作系统的具体解决方案。

Interested in any OS specific solutions.

推荐答案

下面是上一个的并口。

虽然我会建议一个 Arduino的可以非常便宜购买，将只涉及以下code：

Though I would recommend an Arduino which can be purchased very cheaply and would only involve the following code:

/* Blinking LED
 * ------------
 *
 * turns on and off a light emitting diode(LED) connected to a digital  
 * pin, in intervals of 2 seconds. Ideally we use pin 13 on the Arduino 
 * board because it has a resistor attached to it, needing only an LED

 *
 * based on an orginal by H. Barragan for the Wiring i/o board
 */

int ledPin = 13;                 // LED connected to digital pin 13

void setup()
{
  pinMode(ledPin, OUTPUT);      // sets the digital pin as output
}

void loop()
{
  digitalWrite(ledPin, HIGH);   // sets the LED on
  delay(1000);                  // waits for a second
  digitalWrite(ledPin, LOW);    // sets the LED off
  delay(1000);                  // waits for a second
}
