#14 4chアナログ出力(12bitDAC)

Tibbitの配置

Tibbit #14を使うにはTibbit #12が必要ですので2つ挿入します。
Tibbit #12は任意のスロットに挿入してください。

ノードの配置

制御を行うために、functionノードを使用します。

以下のようにフローを配置します。

functionノードの編集を開き、コードに以下を記述します。
chと値を指定します。
v: 0(-10V) – 4095(+10V)

msg.payload = [{ch: 1, v: 4095}];
return msg;

1 2	msg.payload = [{ch: 1, v: 4095}]; return msg;

複数chの値を同時に取得することもできます。

msg.payload = [{ch: 1, v: 4095}, {ch: 2, v: 4095}];
return msg;

1 2	msg.payload = [{ch: 1, v: 4095}, {ch: 2, v: 4095}]; return msg;

ノードの設定を開き、スロットを選択します。
Node-REDデプロイ後、injectノードをクリックすると設定することができます。
