這個是三星的主控S6D1121彩屏(240*320*18bit,262Kcr)的彩屏的驅動程序.
　　采用的是80System+16bit接口
　　不知道是什么原因, 這個主控網上很少有資料,我也是看了好久的DS才明白了一些(全英文, 基本沒中文資料, 反正是不好找到)
　　這是我接觸的第一塊彩屏哦~~
　　如果有用這個芯片的, 可能會有些方便, 也方便交流下使用經驗.

　　這里總共分4個文件:
　　　　common.c,common.h:一些公共的包含與定義,函數
　　　　s6d1121.c,s6d1121.h:主控芯片驅動程序

上一篇隨筆貼出了驅動程序, 這篇文章的代碼主要就是針對上層的調用了, 但是, 其實, 只要是底層的驅動程序能能夠工作了, 圖形設備接口應該就可以隨便移植的咯~
一般彩屏的操作方式應該都是差不多的吧?
　　說明下, 本人不是很擅長圖形方面的算法設計,? 有些程序采用了大師們寫的程序, 有些則是我自己寫的(寫得很差), 不過還是能夠實現功能的哈~
　　我測試程序時是用的死太慘的51單片機測試的, ROM比較小, 只有60KB(整個字庫有大約225KB), 完全沒法裝進去的, 所以就把要用的保存進去了, 所以會有ascii.c/.h文件的存在, 當然, 如果后來會用SD/MMC/U盤, 那就太好了, 不過, 很遺憾的是, SD卡我一直沒有能夠成功讀取~ 慢慢來吧.
　　代碼文件:
　　　　ascii.c/ascii.h:字庫文件
　　　　common.c/common.h:一些公共的頭文件/類型聲明等等(和前面那篇隨筆是一樣的,沒貼出)
　　　　gdi.c/gdi.h:圖形設備接口的實現
　　有了這四個文件, 再加上前面的驅動程序, 把她們放到一個項目下, 就可以寫程序調用了哈, 很方便的說~
