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`

bmp280: read out via DMA in the background This removes any busy waiting on the I²C from the main loop. Initialization is still done in a blocking way. 2022-10-15 20:49:31 +02:00			`bool bmp280_loop(void); // returns true if measurements have been updated`
