Systemライブラリは、時刻取得、遅延処理、割込制御、スリープ、電源状態、リセットなど分類するほどのないものを集めた雑多なライブラリだ。

そして重要な機能も持っている。Arduino風のメイン・ルーチンを提供しloop()処理から戻ってくるとバックグラウンド処理を行う。IEEE802.15.4プロトコル・スタックなどがバックグラウンド処理を必要とするためだ。

【Arduino風のメイン・ルーチン】

だいぶシンプルになったというか見慣れたコードが一番な気がするかも．．．

/*
 * device.hは複数のインクルードファイルをまとめたインクルード。
 */
#include "device.h"

/*
 * wakeup()はウェイクアップ起動時にsetup()より前に呼びされる。
 * 必要なければ関数自体を記述しなくて良い。
 */
void wakeup(void)
{
}

void setup(void)
{
}

void loop(void)
{
  /*
   * バックグラウンド処理を行うために短時間でリターンすること。
   * 長時間ループするようなときはyield()を呼び出すことで
   * バックグラウンド処理を行うことも出来る。
   */
}

* device.hは複数のインクルードファイルをまとめたインクルード。

#include "device.h"

* wakeup()はウェイクアップ起動時にsetup()より前に呼びされる。

* 必要なければ関数自体を記述しなくて良い。

void wakeup(void)

{

}

void setup(void)

{

}

void loop(void)

{

* バックグラウンド処理を行うために短時間でリターンすること。

* 長時間ループするようなときはyield()を呼び出すことで

* バックグラウンド処理を行うことも出来る。

}
