瑞萨开发记录04：按键控制数码管（R5F104FEA芯片）

04.按键控制数字管

  • 一、引脚配置
  • 二、编写代码
    • 1.r_cg_userdefine.h
    • 2.r_cg_timer_user.h
    • 3.my_key.h
    • 4.my_key.c
    • 5.r_main.c
  • 三、烧录程序
  • 四、附录

??按钮的原理很简单，注意抖就行了。本案不使用延迟抖动或定时器抖动。while在循环中定义一个可以随时修改的变量，并根据程序运行所需的时间进行合理的抖动。本实验实现的案例如下： ??开发板上有五个按钮，分别是KEY1-KEY5.功能如下：

KEY1:短按时，数码管每秒 1；长按时，数码管每秒-1；快速双击时，数码管停止移动。 KEY二、短按时，数码管 1； KEY三、短按时，数码管-1； KEY4:短按时，数码管清零，不每秒更新； KEY5:短按时，数字管清零，如果原来处于每秒更新状态，则继续每秒±1。

在这里插入图片描述

一、引脚配置

??根据原理图配置相关引脚，以下按钮引脚设置为输入模式，定时器选择通道1定时50ms。

二、编写代码
