How to set return distance in millimetres for TF-Luna #1
Description
Hello,
I started to use your work (thanks a lot by the way) in order to discover the capabilities of the TF-Luna sensor. Some modifications allowed me to communicate with the sensor in I2C. I asked myself a question, how to have the result in millimeter?
I looked at the documentation provided, I see a reference in the appendix "Appendix II Serial communication protocol" Output format setting ID_OUTPUT_FORMAT=0x05, where it is indicated different possible format
- 0x01 = 9-byte/cm
- 0x02 = PIX
- 0x06 = 9-byte/mm
- 0x07 = 32-byte with timestamp
- 0x08 = ID-0
- 0x09 = 8-byte/cm
Nevertheless these indications are for the serial part and not indicated in the part in appendix "Appendix III I2C register table".
Moreover I noticed in the github repository https://github.com/budryerson/TFMini-Plus_python/blob/main/tfmplus.py, for a serial type communication, the possibility to send to the sensor register values of this type.
- I2C_FORMAT_CM = 0x01000500 # returns a 9 byte data frame
- I2C_FORMAT_MM = 0x06000500 # "
With Github repository, https://github.com/budryerson/TFLuna-I2C_python, how can I get the distance value in millimeters from the sensor?
Thanks in advance,
Best regards,
Jordan.
