Hi,     First, i'am french, excuse my bad english...   I have a problem with my orangepi zero using a bme280 weather sensor with i2c.  (I have 2 sensors) After long search and try, i've found the way to make this sensor working with the orange pi zero, by reading the datasheet where it's indicated that you must put CSB to Vdd to select i2c interface. !!!  - I never wired this pin to my rapsberry pi and it always work , never see in any tuto too!!!   T
