2.9 LCD

Be sure to consult the silicon errata for the proper pinout of the LCD interface. There is a usage note titled, "LCD: Color Assignments of LCD_DATA Terminals" in the device Silicon Errata.

Note that the AM335x EVM "fixes" the pin mapping through a CPLD on the daughterboard, so be extra careful to get the proper mapping!

• A good example of a 24-bit hookup comes from the AM335x Starter Kit shown in Figure 1.

• A good example of a 16-bit hookup comes from the BeagleBone Black that is shown in Figure 2. In this case, the other LCD pins were preserved for use by capes.

• Notice that Red and Blue swap positions depending on whether you are outputting in 16-bit mode vs 24-bit mode (that is, the errata).
