这段代码是一个基于Arduino平台的控制程序主要功能包括
初始化设置引脚模式、初始化编码器、舵机和EEPROM。按键检测处理按钮的单击、双击和长按事件并根据事件执行相应操作。编码器更新检测旋转编码器的状态调整变量值并控制LED闪烁。舵机控制根据设定的角度和速度移动舵机。LED控制根据条件交替闪烁两个LED。
详细解释 初始化 设置引脚模式为输入或输出。初始化编码器、舵机和EEPROM。 主循环 持续检测按键状态。更新编码器状态。控制舵机运动。控制LED闪烁。 按键检测 检查每个按钮的状态。根据按键事件长按、双击、单击执行不同操作。 编码器更新 检测编码器旋转方向。根据旋转方向增加或减少变量值。切换LED状态。 舵机控制 根据设定的角度和速度移动舵机。正向和反向移动舵机。 LED控制 控制两个LED交替闪烁。
