❸ 用51單片機做萬年歷計時怎麼不準,差很多

用51單片機做萬年歷計時，一般都是為了試驗，所以多沒有專門的實時時鍾晶元。晶振頻率會有偏差和溫度系數，雖然日常使用不會有什麼不良影響，但作為實時時鍾，連續累積的偏差就很大了，所以時鍾會不準，差很多。

❺ 單片機做萬年歷用數碼管的優缺點

優點，定時精準，缺點，電路復雜成本高。
數碼管萬年歷的設計原理是利用AT89C5單片機內部定時/計數器TO的模式2（8位自動重裝初值）產生一個時間為250us的信號，再計數4000次產生1S的時間後發出中斷，再由單片機進行數據處理後，送人數碼管（共陰極數碼管）顯示（動態顯示）。

❻ 基於51單片機製作萬年歷，用數碼管，定時器，不用時鍾晶元，不用液晶，怎麼做求大神解，原理圖和C程序

基於51單片機製作萬年歷，用兩個8位一體的共陰數碼管，顯示日期和時間。數碼管位選用兩片74HC138，便於動態掃描顯示，又節省引腳。用3個按鍵調時，K1為選擇調時狀態，K2為加1鍵，K3為減1鍵。

模擬圖如下：
