node-red-contrib-keiganmotor 0.3.0

Keigan Motor node-red node.

npm install node-red-contrib-keiganmotor

KeiganMotor for Node-RED

KeiganMotorをNode-REDから操作するノード

概要

BLEアダプタ又はUSBを搭載したデバイス上のNode-REDで動作します。

v0.3.0 USBに対応

KeiganMotorは以下のデバイスで動作検証してます。

• Raspberry Pi 3 Model B
• MacBook

インストール (npmからインストール)

Node-REDのROOT(.node-red)ディレクトリで以下を実行

 $npm install node-red-contrib-keiganmotor

実行権限の付与 (Raspberry Pi 3)

raspberry piでBLEを実行する場合、スーパーユーザー権限が必要です。

通常のユーザーとしてNode-Redを実行している場合、BLEを実行するためのアクセス許可を与える必要があります。

sudo setcap cap_net_raw+eip $(eval readlink -f `which node`)

依存関係

• noble 1.8+
• kmconnector

サンプル

/sample/motor_demo.jsonの中身をNode-REDのクリップボードに貼り付けるか
以下のフローをNode-REDのクリップボードに貼り付けます。
