單片機:STC15W204S-DIP16@6MHz
LCD : nokia5110LCD
時鐘芯片：DS3231
論壇上做時鐘的方案一大堆，但是用來做電池帶動的卻還沒有。
我想到了一個辦法，用STC的單片機掉電模式運行時鐘，利用DS3231的1Hz來換醒讀秒。
現在能跑起來了，消耗電流在0.5mA+-1mA上下。
不知道這樣18650電池能跑多久。
但是程序上還欠調整時鐘未做，不知道怎樣做光標。
以前1602的話可以直接寫光標反色的，這個5110lcd有人會做光標嗎？求助

做光標應當不難，在LCD的使用說明書中當有求反顯示的啟發。
對于電池供電時鐘，樓主構思是正確的，但選擇材不是很好的（指省電）。
如果仔細選材，做到0.2mA以下絕對沒有問題。
CPU選用超低功耗系列，如MSP430系列。
液晶屏選用無驅動屏，因為帶驅動的，驅動部分耗電！可選用帶驅動液晶的CPU直接驅動。
如果用電子紙，就更省電了，但電子紙貴，就免了吧。
如果不考慮顯示驅動，MSP內部走時鐘程序及所有硬件可以做到20uA以下，驅動顯示電流要看屏的大小即品質，200uA是可以做到的。
