1、儿点说明：1、本文所用液晶控制器为ILI9325320*2402、理解水平有限，如有误，请指正3、驱动原理，每个点用2个字节表示颜色，按设定的方向刷新320*240个点，就可以显示一张图片。一、坐标原点位置的确定首先，你买回来的液晶屏，有一个位置，就是G1和S1开始的位置，我们暂且把它称为物理地址。（这个是没有办法改变的，所以我称之为物理地址，不过坐标原点还是可以改的）S720S1TFTG32O二、屏上的每一点与显示RAM的对应关系。从下图可以看岀：1、每一行的侮一个点地址2.5个字节，所以用三个S表示一个点，720/

2、3=2402、纵向是320行，所以是G1到G320,所以正好是320*240320*240G32OGRAMaddressmaptableofSS=1.BGR=1SS=0.BGR=0S720...S718S717...S715S714...S712S711...S709S12...S10S9...S7S6...S4S3...S1GS=0GS=1DB17...0DB17...0DB17...0DB17...0DB17...0DB17...0DB17...0DB17...0G1G320-OOOOOh-40(W01hw-000
