node-red-contrib-smartnode-seeed/seeed-grove-phy/encoder/locales/zh-CN/encoder.html

this project dependences the node-red-contrib-smartnode package for basic function. based on the smartnode package, this package provide some sersor nodes for Seeed sensors.

<li>配置好节点的每个参数。</li>
<li>使用时，当输入<code>msg.payload</code>为1时。表示打开编码传感节点，节点会每个<code>Interval</code>时间间隔输出当前旋转值；例如转一圈就是20，在转一圈就是40，否则，关闭编码传感节点，停止输出。</li>
