目的： 用1602显示6行数据，分3页显示。每行数据输入后，按确定键保存当前输入的数据。两行输入完成后，按翻页键 翻到下一页，继续输入数据。当翻页键按到第4次时，重新显示第一页之前输入的数据，后面两页依次类推。 目前的主要问题是第4次按下时，无法显示之前输入的数据。 程序如下： #include #include #include #define uint unsigned int #define uchar unsigned char #define ulong unsigned long /******************LCD1602**********************/ ***it LCD_RS = P2^3;
