我没有做过显示屏驱动,电子电路也是才学习的,希望TI工程师们帮下我。我用FPGA驱动DS90C387A,输入端是24bit TTL电平,要做PCB板了麻烦帮看下输出模式是不是应该选择
TABLE 3. Single Pixel per Clock Input to Dual Pixel per Clock Output Application (DS90C387/DS90CF388 only)

三种模式,单像素模式,双像素模式,单像素输入双像素输出 模式,不同模式下的data mapping不同,根据引脚DUAL来配置。
如果DUAL=low,那么为single pixel mode,DUAL=high 为dual pixel mode,DUAL=1/2VCC则为single pixel input, dual pixel output mode,即为您现在这种连接方法。
