NXP JN516X (TWELITE) をプログラミングする（LED)

動作中を示すためのＬチカは良く使うのにライブラリ化してなかったりする。コードが簡単すぎてライブラリ化するまでもないということもあるがもっと簡単に一行だけでも少なくしたいと思ったりすることもある。なのであえてライブラリ化してみた。最大８個まで、どのピンにLEDが繋がっていて点灯にはHIGH/LOWのどちらを出力すればいいのかを指定し登録する。指定時間毎に点滅や指定時間後に点灯或いは消灯などの機能も盛り込んでみた。自分でいうのもなんだが以外に使い勝手はいいかも。

【サンプル】

#include "device.h"

void setup(void)
{
  /* LEDピンを登録 */
  LED::setup(0, Gpio::DIO18, HIGH);
  /* 点灯 */
  LED::on(0);
  /* 消灯 */
  LED::off(0);
  /* 点灯消灯切替 */
  LED::toggle(0);
  /* 1秒後に消灯 */
  LED::off(0, 1000);
  /* 1秒後に点灯 */
  LED::on(0, 1000);
  /* 1秒毎に点灯消灯切替(連続モード) */
  LED::toggle(0, 1000);
}

void loop(void)
{
}

#include "device.h"

void setup(void)

{

/* LEDピンを登録 */

LED::setup(0, Gpio::DIO18, HIGH);

/* 点灯 */

LED::on(0);

/* 消灯 */

LED::off(0);

/* 点灯消灯切替 */

LED::toggle(0);

/* 1秒後に消灯 */

LED::off(0, 1000);

/* 1秒後に点灯 */

LED::on(0, 1000);

/* 1秒毎に点灯消灯切替(連続モード) */

LED::toggle(0, 1000);

}

void loop(void)

{

}
