开源代码 一、页面切换内容详解
1.逻辑解释 首先通过 LCD_Clear(White) 函数将 LCD 屏幕清除为白色。lcd_page 的值增加 1。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_down1时 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 初始时lcd_page 为 0count 为 0。按下按键二一次lcd_page 变为 1。再按下按键二一次lcd_page 变为 2。接着按下按键二一次lcd_page 变为 0完成一次页面循环。同时在这个过程中每按下一次按键一count 值就增加 1。 2.代码详解
