一、页面切换内容详解

1.逻辑解释

  1. 首先通过 LCD_Clear(White) 函数将 LCD 屏幕清除为白色。
  2. lcd_page 的值增加 1。
  3. 然后进行判断，如果 lcd_page 达到 3，则将其重置为 0，实现页面的循环切换。

当检测到按键一被按下（Key_down==1）时：

  1. count 的值增加 1。

这样，通过按键二可以切换页面，通过按键一可以使 count 值增加。

举例来说：

  1. 初始时，lcd_page 为 0，count 为 0。
  2. 按下按键二一次，lcd_page 变为 1。
  3. 再按下按键二一次，lcd_page 变为 2。
  4. 接着按下按键二一次，lcd_page 变为 0，完成一次页面循环。
  5. 同时在这个过程中，每按下一次按键一，count 值就增加 1。

line_flag定义变量存储

  • 当页面为 1 时，根据 line_flag 的不同设置文本颜色，并显示与 count1、count2、count3 相关的字符串。
