这是串口没有打开造成的错误,将设置中的串口打开(或者开关打开),检查传输信号线通断情况,它不是一一对应的,打开信号线的连接端检查。至于你说的测不通的情况没看懂什么意思,请说明白。
下面是官方解释:
If you turn on communication first for Elecsys and after that for the host, the first sample will be ignored. Please make sure, that first the host and after that Elecsys is switched over from ”communication off” to ”communication on”. This applies also to disconnection (e.g. due to technical problems) between Host and Elecsys. |
