I would like to know: are there any problems to be expected if I enable SD card support for the Adafruit Metro M4? I KNOW it has flash, but the SD-card basically will provide me with “unlimited storage”. I see it lacks a few variables, like the pin definition, but I am simply going to copy over all the stuff from the Arduino Due definitions.
EDIT: If I plan to use A LOT of symbols, should I adjust the symboltablesize, too, e.g. to 2048 or 4096 or thelike?
Anything beyond that? - Thank you for your time and help, as always!
