The specific project according to the following several aspects elaborated
(1) hardware circuit
(2) the software code: configuration in the device tree and LCD manual
(3) the picture

a, hardware circuit design is as follows:
[R1 R2 R7], [G1 to G2 G7], [B1 B2 B7] together, their actual tests also tested manually cut line of low 2 bit RGB directly to GND,
2, configuration in the device tree below
3, the following picture, very fuzzy
Thank you kindly, help to analysis analysis, thanks!!
