# ToCoNet\_vDebugInit()

## 解説

TWELITE NET のデバッグメッセージ出力の初期化を行います。

指定した [UART](/hw-api-ref/perifuraru/uart.md) 出力は、アプリケーションの出力と共用で利用され、アプリケーションの出力の間にデバッグメッセージが出力されます。

{% hint style="warning" %}
[Makefile](/twelite-sdk-howto/birudonitsuite/makefile-nitsuite.md) にて`TOCONET_DEBUG`を`1`に設定して、ビルドを実行します。
{% endhint %}

{% hint style="danger" %}
デバッグメッセージは TWELITE NET の内部開発向けで、出力書式等については開示しません。問題の解析等を行う際に、お客様に出力をご連絡いただく場合があります。
{% endhint %}

## 戻り値

なし。

## サンプル

```c
#include "serial.h"
#include "fprintf.h"

tsFILE sSerStream; // use for fprintf
tsSerialPortSetup sSerPort;

void initser() {
  //... setup serial port
  sSerPort.u8SerialPort = E_AHI_UART_0;
  //...
  SERIAL_vInitEx(&sSerPort, pUartOpt);
  
  // setup fprintf
  sSerStream.bPutChar = SERIAL_bTxChar; // lib function
  sSerStream.u8Device = E_AHI_UART_0; // UART0
  
  // setup TWELITE NET debug message.
  ToCoNet_vDebugInit(&sSerStream);
  ToCoNet_vDebugLevel(0); // start with no debug message.
}
```

## 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/twelite-net-guan-shu/toconet_vdebuginit.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.
