Other Parts Discussed in Thread: DM3730
Hello.
I am working on custom board that has 18 bit LCD connection interface. Android is running on the board.
There are four columns in given below table. Column no 1 and 2 shows the standard connectivity between processor and LCD connector . Column no 1 & 3 represents the standard connectivity for an 18 bit LCDwhich is made for 18 bit operation by removing its two LSB from each colour.
Column no 1 & 4 shows the actual connectivity (as per our schematic) between processor and custom LCD (part No. AM-240320MDTNQW-00H).
I cannot change the hardware configuration.
