正点原子7寸液晶屏V1.8版（与V1版除了触屏接口有点改动外，其他没变），在以连续模式写入数据时出现头几个像素点与后面的像素点在颜 {MOD}上有很大反差，主要是体现在红 {MOD}和白 {MOD}时是这样。
    举个例子：我要以红 {MOD}刷屏，我设定起始坐标 CUR_Y=0，CUR_X=0；自动折返点END_X =799；然后我往其像素数据寄存器PIXEL连续写入0xf800（红 {MOD}），头几个点（约10个像素左右）亮度叫大，后续的数据偏暗。在使用白 {MOD}刷屏时依然如此。
   然而，我采用单独写入的方式时颜 {MOD}是正常的。即我每一次写入数据前都对CUR_Y、CUR_X、END_X这几个寄存器重新设定。

另外，测试视频如下：

    好了，直接上图。
下面是图片重复显示，图像的背景本是白 {MOD}，但是由于是连续写入，背景有些偏蓝
下图当中的背景为白 {MOD}的图片显示采用的是非连续方式，很显然这才是正常的数据。

好了，直接上STC90C516代码:
