[X-NUCLEO-IKS01A2测评] 用Nucleo-STM32L476和MEMS board X-NUCLEO-IK...编程 [复制链接]

 

1、从零开始创建一个项目, 选择import，但是因为IKS01A2比较新，只有IKS01A1的库，其实是可以用来测试的。只要对比其中的区别就好，因为识别i2c设备是通过I2C线路的，其实主板并不知道是什么设备。
2、创建后的文件结构如下，

3、文件代码如下，

1. 
   
2. /* Includes */
   
3. #include "mbed.h"
   
4. #include "x_nucleo_iks01a1.h"

4、点击Compile，直接生成可执行文件。把这个文件拖入自动添加的nucleo盘符，就可以flash和自动执行了。
