Title: Arduino w/ More than 256k Memory
Post by: djsfantasi on Aug 26, 2019, 03:42 pm
I have a project running on an Arduino Mega 2560, whose sketch uses almost ALL of the 256k memory available. I'm already using PROGMEM to store several k of tables.

Of course, I need to add additional features to the sketch. Is there a hardware option with say 512k of sketch memory? Is there a shield with extra memory? I'm looking, but is there a thread on minimizing program memory?

This is a critical project, so any advice is greatly appreciated in advance.

There are many Arduino boards with 512 kB or more of flash memory.

Here are some of the most popular:



Is there a shield with extra memory?
Extra memory, yes. Extra program memory, no.
