Silke Hofstra	3ca1162a6a	driver/bmx280: increase accuracy of SAUL pressure readings ... The SAUL implementation of the BMx280 currently returns the pressure in hPa. The sensor, however, actually reads the pressure in Pa, leading to a significant loss of precision. Because the operation range of the BME280 and BMP280 is 300 hPa to 1100 hPa, we can safely increase the precision by a factor of 10 without risk of overflow. The only downside is that readings are now presented as `e1 Pa` (eg 10206e1 Pa).	2021-03-04 21:01:56 +01:00

Hauke Petersen	b7f33bd84f	drivers/bmx280: significant driver rework ... bugs fixed: - move global variables into device descriptor - guard bus access (use acquire and release) added functionality: - enable SPI mode structural improvements: - reduce stack usage - simplify the driver's structure - centralize bus access code - use assertions - cleanup includes - use shortcuts for bus access style changes: - fix line length - cleanup and improve doxygen - unify pointer notation (char *var over char* var) - unify (error) return messages - use `#ifdef MODULE_BME280` instead of `#if defined(BME..)` - unify debug messages -> using `[bmx28] x: msg` scheme	2019-11-22 14:04:37 +01:00
