Hi all,
the topic is a bit older, but it has helped me a lot. I implemented it and it works very well. Thank you!
I attached an SD card reader and a display to the Mega and implemented into my Arduino sketch what the python script is doing. Now I can select a .hex file stored on an SD card by using 2 buttons and can upload anything to an Arduino Uno.
However, I like to extend the software now in way that it is possible to program another Arduino Mega. It seems that some bigger changes are necessary. I created .hex code of a larger mega script and it seems that 2 memory pages are used (there is a break in the adress list).
Has anyone of you tried to resolve this and can provide me with code? I would be very happy about.
