Product Description

Host computer debugging

After connecting with the USB to TTL module, the serial port module is plugged into the computer USB port. Make sure to find the corresponding COM port after installing the driver of the serial port module. Open the host computer software of TOF ranging sensor, connect for the first time, set the baud rate to default 115200, select the corresponding model system in “System Configuration”, and click “Start”. You can see the real-time display of the measured distance column in the “status display”, and the measured value is constantly refreshed as the actual distance changes.

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 enter 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 Nih It is the period of the serial port automatic output, and the upper computer reads the data period 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, input 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. A 10cm offset calibration has been carried out once in the actual mold factory, and it can be used directly. The xtalk calibration is mainly to calibrate 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.
