iMX 93 LCDIF MIPI-DPI Pin mapping

Hi,

I was looking on the LCDIF MIPI-DPI for iMX-93 processor. I want to interface a parallel TFT LCD in RGB555 configuration. Anywhere in the datasheet I didn't find the pin multiplexing for RGB DATA (R0-R4, G0-G4, B0-B4) for RGB555 configuration.

for rgb555, refer to the

https://learn.microsoft.com/en-us/windows/win32/directshow/working-with-16-bit-rgb

should be xRRRRRGGGGGBBBBB

you can refer to the table as below, then connect as xRRRRRGGGGGBBBBB

then choose the register as below

Hi.

Thanks for the valuable information. One more doubt, which register is used to select the different 16-bit configuration (config 1, config2, config3)

Define the pixel color coding to be used by using the dpi_color_coding field in the
DPI_COLOR_CODING register

so for more detailed information, pls refer to the chapter 52.4.2.6 DPI color coding (DPI_COLOR_CODING)

Hi,

This same configuration can be possible in iMX RT-1060 Controllers?

not sure of RT1060, pls create a new case for IMX RT team to double confirm
