Hi Liam
I am having trouble with the example code for the piico VL53L1X and VEML6030 with my Nano33BLE. Can you help me get through these issues please?
For the VEML6030:

This example takes range measurements with the VL53L1X and displays additional

you determine whether the sensor is operating normally and the reported range is
valid. The range is in units of mm, and the rates are in units of MCPS (mega
