Select the parameter configuration column, you can see that there are 4 groups of parameters for users to set or

observe, which is convenient for debugging. Storage parameter 1 is a commonly used setting function. The user can

set the device address, baud rate, distance mode, output cycle, etc., and the parameters are saved immediately after

setting and are effective when power off. Setting method: directly input the value of the required option in the value

of the corresponding function line, and press Enter.

The device address is written directly; please refer to the instruction set for the parameters represented by the

specific options of the baud rate/output cycle, for example, the baud rate 0 represents the default 115200; the

output cycle is also written directly in ms (note that the output cycle is changed here) It is the serial port automatic

output cycle, and the upper computer reads the data cycle is fixed). The correction K can specify the multiple of the

output distance and the actual distance, which is suitable for special purposes. In the "Load Calibration" and

"Disable iic" function lines, the value 1 means enable and 0 means disable.

Storage parameter 2 is generally used for observation. For specific values, refer to the chip specification.

The last two calibration parameter settings apply to the calibration function. For offset calibration, it is

recommended to use a white target object with 88% reflectivity in dark conditions and calibrate at an actual

distance of 10cm. That is, the object is placed at the actual distance of 10cm, enter 10cm in the offset calibration

function line, press Enter to start the calibration, and wait for the parameter display to return to normal to complete

the calibration. The actual module has been calibrated once with a 10cm offset before leaving the factory and can

be used directly. The xtalk calibration is mainly to correct the crosstalk factor generated by the cover window in

front of the probe. This module has been equipped with a dedicated glass cover sheet and has been calibrated at

the factory. When users need to use without cover sheet or use other cover windows, this function can be used for

crosstalk calibration. The specific method is to recommend the use of a gray target with 17% reflectivity. The

crosstalk distance value needs to refer to the chip specification and the actual use environment. After selection, refer

to the upper computer operation process of offset calibration.
