I have originally been working with UNO Arduino smd edition. Blink has always run correctly. Recently I have been working with DFRobot Mega 2560. I have reselected the device to run on uno. I use port 8 which is selected for. When I try to download the blink program I recieve an error message that I am running the mega2560 even though the software agrees that I am running the UNO.I have disconnected the uno and reconnected it. No change.
I am using Arduino 1.8.5 when i open it IDE open but i cant write any thing on it.all IDE are are block.
one more error #include <EPS8226.h> no such file or directory.
