1.2 触摸常见问题

触摸有报点但是没有触摸到屏幕边缘，但鼠标指针已经到了屏幕边缘。对调以下参数。
touchscreen-size-x = <800>;
touchscreen-size-y = <1280>;

举例：13 00 02 01 00
说明：数据类型 延时 数据个数(包含寄存器)  寄存器 寄存器数据
举例：39 00 04 FF 98 81 03
说明：数据类型 延时 数据个数(包含寄存器)  寄存器 寄存器数据  寄存器数据 寄存器数据
//初始化序列常见数据类型：Generic Write0x03：没有寄存器数据0x13：1个寄存器数据0x23：2个寄存器数据0x29：多个寄存器数据
