想自制單片機小手表,求思路

ID:884042 · 發表于 2021-2-12 21:09

由于本論壇禁止直接求程序,禁止伸手黨,所以向大家請教一下大致的實現方法與思路,理清頭緒后我自己來寫程序去實現

自制小手表最近要參加學校科技比賽，就萌發出做一個簡單的小手表的想法，只要能看時間就行。
但后來又想搞的更復雜點，于是就繼續搞這個產品了。以下使用到的材料（包括各種功能IC）：
1  0.96寸OLED屏 1個
2  3.7V電池 1個
3  自己從手機上拆下的無源喇叭1個
4  DS1302時鐘芯片 1個
5  STC15W408S 8K 芯片1個
6  按鍵2個
以下是詳細資料：

現在還有一些功能沒做到，如計算器，可改時鐘，鬧鐘（我在板上裝的喇叭就為這個）等。
現請求各位大佬們幫個忙，給我指導一下OLED屏幕畫點，畫任意線等繪制圖形的函數實現的思路！

用直線插補確定線上點的坐標，畫點lcd更方便，畢竟oled是8個點一起寫的

很好，這是添加更多功能的良好開端。

現在我要解決畫豎線的函數，畫橫線函數及畫點函數
