I was wondering if its possible to send code to the Arduino, and then have it execute this code.
What I'm trying to do is use an Arduino Mega with a bunch of stuff connected to it send code to an Uno with a TFT LCD display to do whatever the Mega tells it to do with the Adafruit GFX Library. I want to add things to this 'system' gradually so I want the whole program hosted on the Arduino Mega, and a minimal amount of code on the Uno.
Sorry I'm really new at this so if its not possible at all let me know!
Thanks in advance,
