# cbToCoNet\_u8HwInt()

## 解説 <a href="#jie" id="jie"></a>

ハードウェアの割り込みの割り込みハンドラです。

{% hint style="info" %}
呼び出し遅延が少ないため、[DIO](/hw-api-ref/perifuraru/dio.md) ポートの制御により直接外部ハードウェアを制御するといった目的に利用できます。
{% endhint %}

{% hint style="warning" %}
割り込みハンドラの処理は最小限にし、速やかに関数から `return` してください。
{% endhint %}

## 引数 <a href="#yin-shu" id="yin-shu"></a>

| 型        | 名前              | 詳細        |
| -------- | --------------- | --------- |
| `uint32` | `u32DeviceId`   | 割り込み源     |
| `uint32` | `u32ItemBitmap` | 割り込みパラメータ |

## 戻り値 <a href="#ri" id="ri"></a>

| 型       | 解説                                                                                                                       |
| ------- | ------------------------------------------------------------------------------------------------------------------------ |
| `uint8` | `FALSE` では [`cbToCoNet_vHwEvent()`](/twelite-net-api-ref/krubakku/cbtoconet_vhwevent.md) を呼び出しますが、`TRUE` を返すと呼び出しを行いません。 |

{% hint style="info" %}
頻繁なタイマー割り込みなどでアプリケーションループに負担をかけたくない場合は `TRUE` を選択します。
{% endhint %}

## サンプル <a href="#sanpuru" id="sanpuru"></a>

```c
uint8 cbToCoNet_u8HwInt(uint32 u32DeviceId, uint32 u32ItemBitmap) {
    uint8 u8handled = FALSE;
    switch (u32DeviceId) {
    case E_AHI_DEVICE_TIMER0: // increment countr on TIMER0
        u32counter++;
        u8handled = TRUE; // no vHwEvent()
        break;
    default:
        break;
    }
    return u8handled;
}
```

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://sdk.twelite.info/twelite-net-api-ref/krubakku/cbtoconet_u8hwint.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.
