1、该模块用于获取气压温度海拔等数据。 vccgnd接电源 sda scl 接iic通信引脚 2、该模块使用iic通信通过iic发送请求相关类的寄存器值芯片获取对应寄存器返回的数据。 所以使用的时调用HAL_I2C_Mem_Write函数 3、调用 uint8_t ret BMP280_Init(); if(ret ! 0x58){printf(BMP280传感器初始化错误\n);while(1);}float P,T,ALT;BMP280GetData(P, T, ALT);printf(BMP280传感器测试数据:\n);printf(气压: %0.4f hPa\n,P);printf(温度: %0.2f ℃\n,T);printf(海拔: %0.2f m\n,ALT);printf(\n\n);.h文件
