❸ 用51单片机做万年历计时怎么不准,差很多

用51单片机做万年历计时，一般都是为了试验，所以多没有专门的实时时钟芯片。晶振频率会有偏差和温度系数，虽然日常使用不会有什么不良影响，但作为实时时钟，连续累积的偏差就很大了，所以时钟会不准，差很多。

❹ C51单片机的万年历程序设计

你可以在我这个程序上修改修改
包括键盘扫描，还有动态显示

❺ 单片机做万年历用数码管的优缺点

优点，定时精准，缺点，电路复杂成本高。
数码管万年历的设计原理是利用AT89C5单片机内部定时/计数器TO的模式2（8位自动重装初值）产生一个时间为250us的信号，再计数4000次产生1S的时间后发出中断，再由单片机进行数据处理后，送人数码管（共阴极数码管）显示（动态显示）。

❻ 基于51单片机制作万年历，用数码管，定时器，不用时钟芯片，不用液晶，怎么做求大神解，原理图和C程序

基于51单片机制作万年历，用两个8位一体的共阴数码管，显示日期和时间。数码管位选用两片74HC138，便于动态扫描显示，又节省引脚。用3个按键调时，K1为选择调时状态，K2为加1键，K3为减1键。

仿真图如下：
