      我自己做了块A133的板子,RGB接口参照『弘迪电子』上A133开发板的电路进行设计,

      和
      0d3163e1-a6b6-415e-bc01-a99ebc56bcfc-image.png ,
      然后自行选购了一款5寸50PIN 800480的显示屏

      据称驱动芯片是HX8282-A11,800
      480模式信号规则如下:

      连接显示屏后测试结果:
      1.有背光
      2.白屏无显示
      串口调试结果如下:

      ,用示波器测量RGB666引脚,均有信号输出。初步判断是驱动程序问题,跪求各位大佬帮忙看一下
