Hi All,
I was running into some issues with the Arduino Leonardo when I was making this project. I just bought the Arduino Touch Shield (Touch Shield - DEV-10508 - SparkFun Electronics) from SparkFun, and it is awesome! Since I have a laptop that doesn't have the extra # keypad on the right side, I decided that I would make one. I planned on using the Touch Shield as well as the Arduino Leonardo (because of the keyboard emulation function, which is so cool!), but I ran into some problems.
I tried to upload the code to the UNO first, because I believe that it's a little more consistent running programs than the Leonardo, since the UNO has been around for a little while longer. I uploaded the example sketch from the Touch Shield page on SparkFun, and it worked perfectly fine. The touch shield worked, and it printed out what numbers I pressed on the Serial monitor.
I then tried it with the Arduino Leonardo, which worked with uploading the code. However, I couldn't open the Serial monitor. My Arduino was definitely plugged into my computer. When I looked at the available ports in Arduino (and also CoolTerm, a terminal program for Mac), my Arduino's Serial Port was gone (I'm on a Mac, so it's always something like /dev/tty.usbmodemfd131, and noticeable). However, when I reset the Leonardo, it fades the D13 LED (I think that's how the board resets), and I can see the port on my screen. I quickly try to open the Serial monitor, it opens, but it doesn't print anything out. Then, it just goes back to the "where's the serial port?" loop again. I've also tried to bootload the Arduino again, but it didn't work after that.
Any Help???
Thanks in advance,
Quin
