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?
1) What OS? 2) Did you install the driver provided in the arduino software?
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Thats a good question, since I down own a Leonardo, but glancing in the driver folders (of 1.0, bit outdated on this computer), there is one specifically marked Leonardo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.
