Currently, the protocol verification is mainly based on the single-byte checksum at the end of the protocol frame. Example code: uint8_t verifyCheckSum(uint8_t *data, int32_t length){ uint8_t sum = 0; for(int32_t i=0;i<length-1;++i){ sum += data[i]; return sum == data[length-1]; Copyright © Nooploop LTd 2023.

However, if two modules are at the same horizontal height and facing each other, the measurement may be affected for both of them. Q3. Why is there no data output from TOFSense-M? Each module has undergone strict testing before shipping. If there is no data, please first check if... - Page 14 Then enter the settings page through the upper computer and select UART mode to write parameters; TOFSense-M S can switch back to UART mode by sending the following serial command to the module several times: 54 20 00 ff 00 ff ff ff ff 00 ff ff 00 10 0e ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff 7b Q7.
- Page 15 Q10.What is the reason for not being able to obtain data in CAN query mode? First, ensure that the wire sequence between CAN devices is correct. Secondly, the TOFSense-M series ports do not include 120R matching resistors. Ensure that the query device's side resistance...
