I'm working an a RPi SPI service to read a BMP280. The BMP280 can produce 16 to 20 bit values for pressure, depending on how it's configured. With the default 16 bits it says it is accurate to within 2.62 Pa.
That's a lot finer resolution than anything I've seen reported. Is weewx going to use the extra data going from 2.62 Pa to 0.16 Pa accuracy, or is it just going to be rounded off?
