stm32HAL库BMP280驱动.zip

用的是i2c1，stm32所有型号都可以用。i2c初始化后调用Bmp_Init()函数初始化BMP280，读取数据时建议先读温度再读气压，这样精度更高： while(BMP280_GetStatus(BMP280_MEASURING) != RESET); while(BMP280_GetStatus(BMP280_IM_UPDATE) != RESET); BMP280_Get_Temperature(); BMP_Pressure=BMP280_Get_Pressure_f(); printf("Pressure %f Pa\r\n",BMP_Pressure);
