2.6寸的彩屏，芯片ili9320，显示彩条或单 {MOD}的图片都可以，就是显示渐变的图片不行，显示渐变 {MOD}时，红 {MOD}好像正常，绿 {MOD}和蓝 {MOD}有很多洋红 {MOD}在里面，附上寄存器设置，请大家给看看问题出在哪了？

要加插值我用双线性插值效果很好

算了把我的代码贴出来吧这个可是原创哇

//-------------------------------渐变填充 ----------------------------------------------------------
   #define Gradient_Vertical 1

//-------------------------------渐变填充 ---------------- ...

非常感谢hexixiaomao的回复，我原本以为只是哪个寄存器没设置正确，我先是用图片取模软件显示图片时出现这样的问题，然后又用渐变的三个颜 {MOD}图片取模试验得到一楼的效果，不知这个原创的代码适不适用于图片取模？
