Can we use QUP3 I2C bus on J19?



  • Hello,
    I am having VOXL2 development kit with system image version 1.2.1.

    I wanted to know if we can use QUP3 I2C bus on J19 (pin number 7 and 8 ) along with Mag connected to I2C bus (pin number 4 and 5) over QUP0 as per connector description? We need to use both I2C bus simultaneously which are connected to slpi_proc. Over QUP3 I2C bus I intend to use SF45 lightware lidar shown over here.
    Any guidance would be appreciated.

    @Aks There are a couple of considerations here. The first is the I2C port to use. In addition to what you are suggesting you could, potentially, put it on the same I2C port as the magnetometer as long as it has a different I2C address. Otherwise, it may be possible to use the port you are suggesting. However, we have not tested anything on that port yet. The other consideration is the device driver. Are you intending to use this sensor with PX4 and does PX4 already have a driver for it? If so, it may just work or it may require some modification to run properly on SLPI.
