For Windows PC

For Mac

Serial setting

You need to connect your PC and MicroUSB Connector(RZ/A1 Ch.0).

Troubleshooting!

If your PC isn't Windows10, you need to install the specified driver from the below URL.
https://os.mbed.com/handbook/USBSerial

Unfortunately, since that is "Unsigned driver", you cannot install as is depending on your Windows version. Since the setting method is different for each PC, please search with "Unsigned driver" keyword on the search site.

トラブルシューティング!

Windows10以外ご使用の場合、ドライバのインストールが必要となります。下記サイトのからドライバーをダウンロードできます。
https://os.mbed.com/handbook/USBSerial

但し、「署名なしドライバ」となっていますので、お使いのWindowsバージョンによってはそのままインストールすることはできません。お使いのPC毎に設定方法が異なるため、検索サイトで「署名なしドライバ」で検索してください。
