GT911 4.3寸屏幕 800*480 的配置信息表

hjjkkl

最近买了正点原子4.3寸电容屏，发现不是用的GT9147的触摸驱动芯片，而是用的是GT911驱动芯片。我在调试的时候不小心把配置表给写成GT9147的了，后面试了好久，那个配置信息还是不对，后面重新买了块屏，我把读出来的配置表信息分享给大家

只是没太明白，为什么设置的分辨率反而是 0x201 和 0x503 ？ 十进制就是 513 x 1283 ?
不应该是个800 x 480 的 屏吗

配置寄存器总共有186个，楼主省略了第一个 ConfigVersion 和最后2个寄存器（CheckSum , Fresh）。

表中开头的两个 0x01E0  = 480，0x0320 = 800
