Hi @ all,
is there a way to change the programming speed at "Arduino Mega 2560" from 115200 to 57600.
That would require two changes, one easy, one not so easy.
First the easy one, the baud rate entry for the mega2560 board selection in the arduino core file boards.txt would have to be edited to change
Second the harder task. You would have to take the source file for the mega2560 bootloader code and change it for the new baud rate and recompile the bootloader and then burn the modified bootloader code on to the board. This can't all be done within the arduino IDE so you would have to do some research on how to accomplish all that.
