- Print *_timer_cb consistently (add units "C" and "%" at .2f precision)
- Guard HTU21DF and SI7021 from co-existing (both devices are on the same I2C address)
- Differentiate between BME280 and BMP280 in metrics
- Update README with timing information
- Link in all drivers
- Plumb BME280 all the way through to Prometheus.
- Add README detailing the diff between BME280 and BMP280
- Refactor source files to be *_drv.c to avoid naming clashes with
upstream libraries.
Also, remove DHT dependency and add a note in mos.yml to have
application owners include those libraries. Without them, we'll compile
no scaffolding. With them, we'll pull those in based on -DHAVE_* macros.
