ID:329372 发表于 2018-5-14 11:32 | 显示全部楼层 |阅读模式
BMP180 驱动程序，基于 STM32f103ZET6 ，开发平台：Keil 5 ，库版本：HAL
(BMP180 driver, based on STM32f103ZET6, development platform: Keil 5, library version: HAL.)

使用硬件IIC的方式，读取 BMP180 中的寄存器值（0xAA）

利用LPME1函数修改，硬件IIC可完成目标，但不规范

开发平台：Keil 5

下载下来了，意义不大，只有几句代码，没注释，没按数据手册校准，读出的数据也不知道为啥是float类型，算了还是对照数据手册重新做吧。
