Detailed Description
BME280 Environmental sensor.
- Note:
- Note: Interface selection is done by the value of CSB (chip select)
- if CSB is pulled-up, I2C interface is active.
- if CSB is pulled-down, SPI interface is active.
- After CSB has been pulled down once (regardless of whether any clock cycle occurred)
- the I2C interface is disabled until the next power-on-reset.
