原因:SD卡会出现无法读取,直到设备再次上电。 reset() 软复位 ;在实际操作中,有时可能需要对设备进行电源循环,这可能是必要的,因为有时它可能会有点混乱,尤其是如果改变了SD卡的状态。所以如果设计一个PCB /电路包括jq6500模块可能是值得包括这样的能力(即动力装置通过MOSFET可以打开/关闭时)。 getStatus() 状态...

The key behind all this is a flexible output command and assignable actions. So how does it work? Everywhere, where you can define some output you can include place holder for special values like current temperature or z-position. It doesn’t really matter for which function the output was ...
