Detailed Description

: Main program body

This is an example of use BME280_driver with STM32 platform and HAL library. There is one sensor connected to SPI1 in 4-wire mode, chip select pin is defined as BME280_NCS and driven by software. Results are stored as integers inside bme1_data structure. Sensor if initialized, then configured. Inside infite loop single measure is forced once per 500ms.
