Hello dear friends, please help me!!!!
Can I charge a code build for arduino Mega on a Arduino uno?
You can change Aruduino sketches with Windows, IOS and Linux machines.
Ignoring hardware differences, C++ code runs on the Mega and UNO.
@andresw, What made you think that your question has anything to do with the Website and Forum section which is clearly stated to be for "Improvements for the web system, applications to moderator, spam, etc."? I have suggested to the Moderator to move it to the Programming section.
This sort of carelessness makes unnecessary work for the Moderators.

The answer is "it depends".
What do you want to do?
Use the Mega's bin or hex file and upload it in an Uno? Possible problems:
*
port mapping and hence the wrong pins are manipulated
*
peripherals that are not available in the Uno (e.g. additional timers)
Recompile your sketch and upload to Uno? Depends on the sketch.
*
direct port manipulation will manipulate the wrong pins if not adjusted
*
directly controlling peripherals that are not available in the Uno (e.g. additional timers) will result in compile errors
*
interrupt conflicts depending on libraries used will result in linker errors
Try compiling the code for an UNO and see if it compiles successfully. A problem you are likely to run into is that the code is too large, or uses too much dynamic memory, so is impossible to run on an UNO.
