6、stroge模块和按键模块

大家好，我是讯享网，很高兴认识大家。

6.1、存储模块

存储模块使用的是P25Q32H，封装USON3*2，引脚定义如下所示。

具体配置如下所示

该芯片的驱动程序和W25QXX系列基本一致，移植于之前的W25Q128驱动，主要内容几乎没变化。

后续的存储线程只需要调用这里面的读写函数就可以了。比较简单，参考W25QXX系列驱动和本芯片datasheet即可。

6.2、按键模块

在这里插入图片描述

一共是7种触发按键的事件。其中，双击按键，长按时间都是通过修改文件内的宏定义修改时间的，但是LONG_PRESS_HOLD这个事件的触发间隔确实写死的(一个button_ticks出发一次)。这不符合我的要求，于是将头文件内部宏定义修改为如下所示。

#define TICKS_INTERVAL 5 //ms //心跳间隔 #define DEBOUNCE_TICKS (20/TICKS_INTERVAL) //MAX 8次 40ms 滤波时间 #define SHORT_TICKS (200 /TICKS_INTERVAL) //双击的时间间隔 #define LONG_TICKS (500 /TICKS_INTERVAL) //长按的时间判断 #define LONG_HOLD_EVENT (200/TICKS_INTERVAL) //触发长按后，多长时间触发一次LONG_PRESS_HOLD事件

之后在button_handler()函数添加如下内容。
到这对于LONG_PRESS_HOLD事件的修改就做完了。
