You'll need to get the official Bosch BME280 driver, available on GitHub. The wrappers will use Ruuvi Interface internally, so you don't have to port these to use BME280 on a new platform. You're required to port Yield and delay functions, GPIO functions and SPI functions.

General usage is:

static struct bme280_dev dev = {0};
dev.dev_id = bme280_cs_pin;
dev.intf = BME280_SPI_INTF;
dev.read = ri_spi_bme280_read;
dev.write = ri_spi_bme280_write;
dev.delay_ms = bosch_delay_ms;
bme280_init(&dev);
