I'm trying to use a Leonardo, and am trying to use the serial monitor for debugging, to make "trace" messages. When I click "Serial Monitor", it says the port is not found, and to change it in the Tools > Serial Port. Then, sometimes I can click it, sometimes I can't. When I can, nothing shows up (Programming?) When I can't, the menu is grey. Any help?
Two things
- What OS?
- Did you install the driver provided in the arduino software?
-
Windows 7
-
The software has previously worked. The only thing is that I've gotten a new Arduino board. Wouldn't the driver be the same?
Thats a good question, since I down own a Leonardo, but glancing in the driver folders (of 1.0, bit outdated on this computer), there is one specifically marked Leonardo
What do you mean when you say you got a new board?
Did you have a uno (or any 328 based) board and then you got a Leonardo? Or you had a Leonardo and got a new Leonardo? Where did you buy the "new" board from?
If the problem happens on some times but not always, this probably will help you http://arduino.cc/forum/index.php/topic,118440.0.html
I had a leonardo and got a new one.
I've now found that my board shipped with dead pins. If there is a defect here, might there also be one in the serial communication portion?
Damage is damage. Something happened to the board that shouldn't have, so I would call the whole thing suspect.
