add('A', doLA, "getLA"); delay(100); } void loop() { delay(2); command.run(Serial); }在这个示例中,我们创建了两个Commander实例:command和command2,分别用于处理一级命令和二级命令。通过定义回调函数 doL 和doLA,我们可以在收到相应命令时执行自定义的操作。

Re-maps a number from one range to another. That is, a value of fromLow would get mapped to toLow, a value of fromHigh to toHigh, values in-between to values in-between, etc. 我使用Arduino采集到土壤湿度模块的数据,200-100不等,Arduino读取模拟量的最大数值为1023,而这么大的数据,也并不...
