這個我這沒入門的都能看個大概，如果這個都不明白，建議還是耐心的學一下基礎的東西，這玩意貪不得快。
那些代碼無非就是定義了一些字符串短的替代長的在寫程序的時候相對簡單些，還有些引腳定義，一些子函數(shù)定義，最下邊那一堆是一個圖片的數(shù)組。

作者: 東仔 時間: 2020-11-27 09:18
在.h文件定義變量、端口號等等，可以減少主程序的代碼量，更清晰一點，方便看程序。

作者: 落日殘霞 時間: 2020-12-3 11:31
定義lcd12864端口的變量

作者: rayin 時間: 2020-12-5 09:03
.h文件定義了控制信號reset，EN，RS等引腳的GPIO高低電平，顯示函數(shù)的聲明，后面的數(shù)組是顯示圖片的數(shù)據(jù)

作者: suncat0504 時間: 2020-12-5 11:07
定義和12864的硬件接口信息，以及接口函數(shù)聲明。通過這些接口和函數(shù)實現(xiàn)嵌入式開發(fā)板與12864之間進行通訊。最底下的photo代碼是預先定義一個圖片的數(shù)據(jù)。用來在液晶上顯示圖片。

是一些圖片數(shù)數(shù)據(jù)，如圖片多大，字符多大，什么字體等
