# SERIAL\_vInit()

## 解説

UART （シリアルポート）の初期化を行う。

本関数では１つの UART ポートの初期化を行い SERIAL ライブラリによるアクセスを可能とします。

{% hint style="info" %}
初期化時に SERIAL ライブラリが内部的に利用する FIFO バッファーのメモリ領域を静的に確保する必要があります。
{% endhint %}

{% hint style="info" %}
同時に、出力用の [vfPrintf](/hw-api-ref/perifuraru/uart/fprintf-raiburari/vfprintf.md)(), [vPutChar](/hw-api-ref/perifuraru/uart/fprintf-raiburari/vputchar.md)() を行うため [tsFILE](/hw-api-ref/perifuraru/uart/fprintf-raiburari/tsfile.md) 構造体の初期化を行っておきます。
{% endhint %}
