How to configue I2C slave machine address on TF-luna Lidar?

Q:TF-luna failed to set a different I2C address from the default address of 0x10. It does not work as I2C device anymore. Any suggestion to correct this or reset the device?
A: Firstly,TF-luna is wired to determine whether it is an I2C device or not, and does not need to be changed by commands. When you need I2C mode, ground the configuration input #5 as below.

Secondly, if you want to configue I2C slave machine address of TF-luna, just change the register value of I2C register table.
