Hi!

I connected display data to GPIO_DISP_B1_XX and GPIO_DISP_B2_XX pins. I read manuel that I have to connect data 0 to GPIO_DISP_B1_04, but is it GPIO_DISP_B1_04    R0 ? Im not sure that.  R0...R7 ,B0...B7,G0....G7 should I connect the data of GPIO_DISP_B1_XX to these pins in order. Is there a document about this subject? Thank you

Hi @eRgnmrt,

Sorry for the delayed response. Yes, the image shown is suitable for 24-bit use. If your application follows this scheme, you can follow this image.

BR,
Edwin.

Hi @eRgnmrt,

Please look into the following application note (AN12302), specifically "Figure 6. 24-bit RGB888 eLCDIF interface to 18bpp LCD panel". I believe it will prove very useful for your inquiry.

BR,
Edwin.

Hi @EdwinHz 

What is the meaning of pins D17,D16,D9,D8,D0,D1 in Table 6?
Where do I connect the R6,7-G6,7-B6,7 pins to?

Hi @eRgnmrt,

Table 6 shows the connection of a 18 bit per pixel LCD. In that case, pins D17, D16, D9, D8, D1 and D0 end up being left over.

From what you mention, I believe you are using 24bpp, so the RGB connections would equate to the values shown on "Figure 1. Data for 1 pixel" (D7-0 Blue, D15-8 Green, D23-16 Red):

There was no information about this in the datasheet. We connected it directly. (We are not sure any shift each pins?)

Is the link in the picture suitable for 24-bit use?Is that true?

thank you
