Waveshare BME280 - BASIC DATA READING FLOW; Step 1: Initialize OS and Peripherals; Step 2: Implement Communication Functions; Step 3: Obtain and Display Sensor Data

BME280 Environmental Sensor
The basic flows to read BME280 data are:
Step1: Initialize for OS and peripheral
Step2: Realize Read, Write and Delay functions (I2C and SPI), and assignment the
functions pointer to bme280_dev structure as publics, then transfer the pointer of
structure to initialization function int8_t bme280_init(struct bme280_dev *dev) .
Initialize BME280 device.
Step3: Calling int8_t stream_sensor_data_forced_mode(struct bme280_dev *dev) or
int8_t stream_sensor_data_normal_mode(struct bme280_dev *dev) to get data of
BME280 sensor and print them to console or PC.
