The CPORT minitoolbox supplies basic functions to open, configure, read from and write to serial and parallel ports under microsoft Windows 95/98 and (maybe) NT. The toolbox is implemented using a series of MEX files and M files. Requires Windows95/98/NT and Matlab 5.x Included ...
int fd = open_serial_port(); if (fd == 1) { return 1; } const char *message = "Hello, serial port!"; write(fd, message, strlen(message)); close(fd); return 0; } 5、我们需要编译并运行我们的程序,在终端中,可以使用以下命令来编译我们的程序: ...
ORSSerialPort is an easy-to-use Objective-C serial port library for macOS. It is useful for programmers writing Objective-C or Swift Mac apps that communicate with external devices through a serial port (most commonly RS-232). You can use ORSSerialPort to write apps that connect to Arduino...

Write()gives the data to the serial port. If the operation is asynchronous, the callback results in the number of bytes that were actually transferred to the driver. You need to check yourself if this is valid or not. In the synchronous case, the data is simply thrown away. TheSerialPo...
