Serial Communications,

CodePudding user response:

Using SenData function can ah

CodePudding user response:

refer to the second floor xianglitian response:

using SenData function can ah

You mean this function can be achieved in the code? For detailed guidance

CodePudding user response:

Do you want in SenScanData function implementation send sn number, you need to open the serial port, serial port configuration. After send the sn number, and then close the serial port, under Windows specific practices:
CreateFile created a serial port, SetCommState set properties, WriteFile send data, CloseHandle to close a serial port,
Specific code can be found online, you can check it,

CodePudding user response:

The upstairs, parameters must be configured properly

CodePudding user response:

Is mainly operating method of the serial port, and then put data into a BYTE array, etc
