Page 6: Use And Configuration
1.2 Use and configuration 1.2.1 The role of configuration parameters Users can modify the configuration parameters to the module through the serial port of this mmWave senser to adapt to different application requirements. The configurable radar detection parameters include the following : The farthest detection distance ... -
Page 7: Visual Configuration Tool Description
1.2.2 Visual configuration tool description In order to facilitate users to quickly and efficiently test and configure the module, the PC terminal configuration tool is provided. Users can use this tool software to connect to the serial port of the module, read and configure the parameters of the module, and also receive the detection result data reported by the module, and make real-time visualization display, which is greatly convenient for users. -
Page 8: Communication Protocols
Blue line: moving target energy Red line: static target energy value Green line: the set sensitivity value on each distance gate on each range gate 2 Communication protocols The 24GHz mmWave Sensor for XIAO communicates with the outside world through a serial port (TTLlevel). Data output and parameter configuration commands of the radar are carried outunder this protocol. -
