Hello there,
Is there any document regarding how RGB interface cd is connected to DA14695 G0,G1,B0, B1, R0, R1?
Is it possible that I can use a MCU 8080 interface LCD in DA14965 GDI framework?

Hi,
LCD IF is described at Cap 22.2.1 Parallel LCD Interfaces pag 199 of the datasheet.
Table 105 shows HSYNC/VSYNC Parallel I/F Pinout
Table 106 shows JDI Parallel I/F Pinout
MCU8080 is not supported.

Hello Paolo,
I found 6bit mode supported in document, but it transfer 2bit R, 2bit G, 2bit B in one clock tick. But most 6 bit rgb mode supported I found, is kind of serial mode - 6bit R, 6bit G, 6bit B. So, my question is if the 6bit rgb mode is only supported for several specific display dirver?
Hi auzzz,
Sorry for jumping in. The DA1469x has only 6 pins for the RGB. So, you will have to take the 2 most significant bits from each color from the LCD that you are using and connect them to the DA1469x.
The 2 MSB from each color are enough to fully represent the displayed image. The other 6 LSB are used for the color intercity. We are using 2 bits from each color just to save pins.
In the Parallel LCD Interface, the controller will take out all the color bits for each pixel in only 1 clock cycle.
For instance, in case of the RGB88 : 24 parallel bits (color information : of which only 6 are available in the DA1469x device family) will take out in 1 clock cycle.
The color format is not depended on the interface (serial, parallel, etc. ) will be used.
It’s possible to have various output color formats such as RGB565/RGB666/RGB888, but in all cases the DA1469x will take only the 2 MSBs from each color as an output. So, in the parallel interface, 6 bits will take out in 1 clock cycle.
Thanks, PM_Dialog
Thanks for your kind informative reply. Now I understand that it's actually a 64 color pallette for RGB mode.
