基于STM32F401RE开发板的X-NUCLEO-IKS01A3传感器测试之七LSM6DSO点击测试 [复制链接]

 

    今天继续进行LSM6DSO的点击测试，按照范例，启动单片机后，按动用户按钮，依次进入单击状态、双击状态和停止状态，在单击状态时，敲击开发板，程序能识别，在双击状态时必须双击开发板程序才能识别，在停止状态时不识别敲击。为了让测试更直观，我添加了一个变量来记录敲击次数，并显示在屏幕的右下角。切换状态时，计数值清零。

    下图为测试过程：

    这是进入等待用户按键状态的界面：

    按下用户按键，依次进入单击状态、双击状态和停止状态：

    下面是单击计数：

    下面是双击计数：

    下面是添加了LCD显示代码的函数：
