      Hi,
      I connected Lightware LW20/C on one of the I2C port on VOXL2 J19.
      It is QUP3, and the pins I used are

      7	I2C3 SDA 3P3V	slpi_proc, SSC_QUP3
8	I2C3 SCL 3P3V	slpi_proc, SSC_QUP3

      and power & ground.
      I also installed a customized voxl-px4 which will start lightware_laser_i2c with the I2C address 0x66.
      On VOXL2, I edited voxl-px4.conf file by adding DISTANCE_SENSOR=LIGHTWARE_SF000.
      However, I cannot see any parameter regarding rangefinder... like SENS_EN_SF1XX.

      I have done using LW20/C with UART connection successfully, but I2C does not work..
      Can anyone give me any advise to use it via I2C?

        @voxltester That is not a normal option to choose via voxl-px4.conf. You will need to hand modify the startup script /usr/bin/voxl-px4-start to properly start the driver in i2c mode. Use option -b 4 to select that i2c bus.
