# \<PAL\_MAG>

[開閉センサーパル OPEN-CLOSE SENSE PAL](https://mono-wireless.com/jp/products/twelite-pal/sense/amb-pal.html) のボードビヘイビアです。

```cpp
void setup() {
  auto&& brd = the_twelite.board.use<PAL_MAG>();
}
```

開閉センサーパルのセンサーは磁気センサーで、２本の信号線の割り込みの入力のみです。

```cpp
const uint8_t PAL_MAG::PIN_SNS_NORTH = 16;
const uint8_t PAL_MAG::PIN_SNS_OUT1 = 16;
const uint8_t PAL_MAG::PIN_SNS_SOUTH = 17;
const uint8_t PAL_MAG::PIN_SNS_OUT2 = 17;
```

PAL\_MAG::PIN\_SNS\_NORTHはセンサーがN極を検出したとき、PAL\_MAG::PIN\_SNS\_SOUTHはセンサーがN極を検出したときに割り込みが入ります。

スリープ前に以下の設定をしておきます。

```cpp
pinMode(PAL_MAG::PIN_SNS_OUT1, PIN_MODE::WAKE_FALLING);
pinMode(PAL_MAG::PIN_SNS_OUT2, PIN_MODE::WAKE_FALLING);
```

起床時に起床要因のIOを確認します。

```cpp
uint8_t b_north = 
  the_twelite.is_wokeup_by_dio(PAL_MAG::PIN_SNS_NORTH);
uint8_t b_south = 
  the_twelite.is_wokeup_by_dio(PAL_MAG::PIN_SNS_SOUTH);
```

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://mwx.twelite.info/v0.1.3/boards/pal/pal_mag.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
