Initial BMP280 integration This version uses only blocking i2c calls, and long transfers will probably cause frame loss. Also, if no BMP280 is present, the firmware will not start up and hang in an endless loop instead. 2022-10-08 20:50:08 +02:00			`#ifndef BMP280_H`

Try to make BMP280 communication more resilient If communication times out or a NAK is received, this is now recognized and sensor values are flagged as invalid. The communication then restarts on the next regular cycle. This is still to be tested. 2022-11-09 20:47:13 +01:00			`bool bmp280_loop(void); // returns true when measurement cycle has terminated (successfully or with error)`
