NHD-7.0-800480EF-20 Color Modes

Just to keep things organized, I  thought I'd raise this as a separate question.

Does the NHD-7.0-800480EF-20 support only 24-bit BGR pixels, or can I use any of the other SSD-1963 color modes?

Regards,
Tim Cole

  Hello Tim,
  
  NHD-7.0-800480EF-20 supports Up to 24-bit BGR. It can support any of the other SSD-1963 color modes.
  
  Have a good one!

  Hi Paul,
  Thanks for the quick answer.
  
  Just to clarify, is there anything more needed to specifying the color mode than simply sending the correct command to the SSD-1963?
  
  Cheers, Tim

  The color mode for the SSD1963 is dictated by the interface you are using. The table from page 17 of the SSD1963 datasheet that shows the different available interfaces and their corresponding color depth/pixel arrangement.  On page 78 (second attached image) the spec gives an explanation of the set_pixel_data_interface command (0xF0).  This is the command you will use to select what interface/pixel format you want to use.  You will notice from these images, when using the 8-bit interface for the SSD1963, you must use 24bpp color depth (3 writes per pixel).  The NHD-7.0-800480EF-20 controller board only allows the user to use an 8-bit interface, while the NHD-7.0-800480EF-34 allows for up to an 18-bit interface (16-bit being the most common).  The two controller boards are identical except for the FFC connectors you would be connecting your MCU to (20-pin connector vs 34-pin connector).  The board has solder pads for either connector, allowing you to modify it if you have the means to.
