三星S6D1121主控彩屏(240*320*18bit,262K)驱动程序
2024-05-07 01:26:41
这个是三星的主控S6D1121彩屏(240*320*18bit,262Kcr)的彩屏的驱动程序.
采用的是80System+16bit接口
不知道是什么原因, 这个主控网上很少有资料,我也是看了好久的DS才明白了一些(全英文, 基本没中文资料, 反正是不好找到)
这是我接触的第一块彩屏哦~~
如果有用这个芯片的, 可能会有些方便, 也方便交流下使用经验.
这里总共分4个文件:

上一篇随笔贴出了驱动程序, 这篇文章的代码主要就是针对上层的调用了, 但是, 其实, 只要是底层的驱动程序能能够工作了, 图形设备接口应该就可以随便移植的咯~
一般彩屏的操作方式应该都是差不多的吧?
说明下, 本人不是很擅长图形方面的算法设计, 有些程序采用了大师们写的程序, 有些则是我自己写的(写得很差), 不过还是能够实现功能的哈~
我测试程序时是用的死太惨的51单片机测试的, ROM比较小, 只有60KB(整个字库有大约225KB), 完全没法装进去的, 所以就把要用的保存进去了, 所以会有ascii.c/.h文件的存在, 当然, 如果后来会用SD/MMC/U盘, 那就太好了, 不过, 很遗憾的是, SD卡我一直没有能够成功读取~ 慢慢来吧.
代码文件:
ascii.c/ascii.h:字库文件
common.c/common.h:一些公共的头文件/类型声明等等(和前面那篇随笔是一样的,没贴出)
gdi.c/gdi.h:图形设备接口的实现
有了这四个文件, 再加上前面的驱动程序, 把她们放到一个项目下, 就可以写程序调用了哈, 很方便的说~
