stm32 HAL读取BMP388传感器的数据
BMP388的官方链接：
https://www.bosch-sensortec.com/products/environmental-sensors/pressure-sensors/bmp388/
代码的开源路径：
https://github.com/boschsensortec/BMP3_SensorAPI
主要是参考examples里面的例子。
主要修改是commom.c里面的内容。很多不用的可以注释掉。
在main函数里面先调用Bmp388_Init，然后在while循环里面使用Get_Bmp388_Data即可。
需要留意的是，采集间隔的时长。
修改后的代码：
