I recently picked up one of the ILI9340C SPI displays. I can run the graphics test programs without issue, however it takes 3047ms for the image to load. That seems a little slow, though I do understand that the data has to run through the SPI interface twice.
Does anybody have some experience in getting image updates onto this display a bit faster? What would really be ideal is if there was an image buffer on the display itself that I could dump to the screen with a command. If such a feature exists, though, I haven't run across the documentation for it.
