Alternatively, I considered adding a routine to my sketch to dump the ILI9341 screen memory to the serial port, but I can't find a way to read the screen memory. Can that be done?

Hi Mark,
Yes it can be done.??0x2E command is RAMRD.?

If anyone is interested in a c function to dump screen memory, I can post? c code that outputs x,y,565color.
The starting program was Reed's V6 code.
