Hi Klein,
Consider also this scenario, from the MPIDE forums:
I would like to send a hex file to a customer and give them the ability to upload without sending the whole project.
. I've posted the link on the previous post. Make is (a solution but) definitely not for them (clients), and is scaring for beginners.
Anyway, is not my problem (even if it is a real one considering all the cases) as I'm successfully using avrdude-GUI with the last version of avrdude. The OP from the MPIDE forums said also:
I wish MPIDE could be used to upload hex files without compiling, that would be easy!
Best regards,
Vasi
