Interface for BME280 basic usage. The underlying platform must provide functions for SPI and/or I2C access, ruuvi_interface_spi_bme280.h and ruuvi_interface_i2c_bme280.h.

Testing the interface with ruuvi_driver_sensor_test.h

rd_status_t err_code = RD_SUCCESS;
rd_bus_t bus = RD_BUS_NONE;
uint8_t handle = 0;
rd_sensor_init_fp init = ri_bme280_init;
bus = RD_BUS_SPI;
handle = RUUVI_BOARD_SPI_SS_ENVIRONMENTAL_PIN;
err_code = test_sensor_init(init, bus, handle);
err_code = test_sensor_setup(init, bus, handle);
err_code = test_sensor_modes(init, bus, handle);
