I can connect directly to the serialport, using /dev/ttyUSB0 for example. Fixing this would greatly improve the generic use of serialport by other nodejs modules, that use the serialport.list function to automatically find a device, such as in firmata/johnny-five. Thanks Activity Sign up ...
串口(Serial Port)是一种用于数据传输的接口,常见的有RS-232、RS-485等标准。在Linux中,串口通常以设备文件的形式存在,如 /dev/ttyS0、/dev/ttyUSB0 等。 查看串口占用端口的方法 方法一:使用 lsof 命令 lsof(List Open Files)命令可以列出当前系统打开的所有文件,包括设备文件。 代码语言:txt 复制 sudo lsof...
首先需要导入Java串口通信库,比如RXTX库,并初始化串口: importgnu.io.*;publicclassMain{publicstaticvoidmain(String[]args){// 获取系统中所有的串口Enumeration<CommPortIdentifier>portList=CommPortIdentifier.getPortIdentifiers();// 遍历所有串口while(portList.hasMoreElements()){CommPortIdentifierportId=portList.next...
