The display controller I used has 24 bit output R[7:0] , G[7:0], B[7:0]. In the old board, DS90C387 is connected to the display controller. As they both have 24 bit interfaces, there is no problem. Well, on the new board, DS90C387R is used. DS90C387R has 12 bit input, and there is two data per clock for 24bit RGB. I don't know how to connect DS90C387R to the display controller and how the 24 bit RGB data transfers to DS90C387R through 12bit interfaces.
Could anyone will me a help? Thanks.
