A few days ago I bought my second MEGA2560 to replicate my current projects. This second MEGA2560 is really a MEGA2560 R2 ( there is no info about it here, or I can not find it) and this board does not work with the First MEGA2560 that I had.
It upload the SAME code to both Boards and on “first release” it works well, but on “R2” it does not work :-(. The last board was “slow” and does not work well. My code is a simple Stepper Motor controller and it fails on “R2”.
After google a little bit , I tried to upload the HEX of “old” 2560 to the new R2 but I’ve got the same problems than before.
Have you any experience of this “R2”? Do you know which HEX is the best for this board?
Thanks in advance fo your attention, Best Regards from Barcelona!
