Thank you for notifying me. It's fixed now:

The new Serial_LCD release 15 brings faster dialog box -- twice as fast as previously -- and the long awaited-for readPixel function to get the colour of one pixel.

Code: [Select]

As always, more details on my website.

There is a thread running at the moment where we were talking about having animated gauges by blitting graphics from the SD. I said I wasn't sure if the 4DS screen did that fast enough. Do you have any numbers for that?

I gather your saveScreenSD is a loop that reads all the pixels and writes them to SD and readScreenSD does the reverse?

Actually, in both cases, it is a single command sent to the screen and the whole process is handed by the screen controller.
