Hi!
I need to connect software-via an 2560 arduino to a atmega 128 microcontroller (those are already connected hardwre via).
The main issue is that the arduino have a User Interface (using a UTFT device) where I have programmed buttons to upload programs (hex files are in a 1gb micro SD) to the other microcontroller in an independent way.
I need a function. When I call the function using my button, arduino upload an aatmega128 hex (readed from the SD) file to the other micro.
Help please!...Im so worried
I think Nick Gammon has a sketch to do exactly this?
Someone here does.
Take a look at that - it may have done all the work for you, or if not, most of it.
Thank you very much... If you get more info, please, send me it!
Crossroads has done work based on Mr. Gammon's software.

I have done hardware that runs Nick Gammon's software, to be technically correct.
