i.MX7 LCD Pinout

[oneil]

I am looking at Table 13-3 in the i.MX7 DRM:

I would like to use 18-bit DOTCLK mode to interface with an RGB display. I am noticing that there is no color associated with the different LCD_DATAn signals. Is this because the pinout with respect to the pixel color can be arbitrarily defined? If not, which three groups of six pins correspond to R, G, and B?

Thanks!

Hi @oneil,

I hope you are doing well.

Please see the 18Bit LCD connections below:

LCD_DATA[17:12] = R[5:0]

LCD_DATA[11:6] = G[5:0]

LCD_DATA[5:0] = B[5:0]

Thanks & Regards,

Dear riteshmpatel,

I have the same question, but with 24 bit LCD interface.

Shall I estimate, that the signals are as follows here:

LCD_DATA[00-07] = B[0-7]

LCD_DATA[08-15]=G[0-7]

LCD_DATA[16-23]=R[0-7] ?

I mean LCD_DATA[00] = B0, LCD_DATA[01]= B1, .... and LCD_DATA[22]=R6, LCD_DATA23=R7, correspondingly. Am I correct?

Where can I find a concrete declaration of these signals in the documentation? I cannot find it either in the datasheet nor in the reference manual.

Thank you Ritesh, this is exactly what I was looking for.
