Axon II Not Being Recognized By PC
Mastermime:
Hello,
My Axon II is not being recognized by my laptop or my desktop. All the drivers are installed. First, I connected to my laptop via USB. It worked great and displayed as Siliconlabs something. Then I wheeled my robot across carpet (possible ESD buildup?) to my desktop and connected it to my desktop. I got nothing. I don't know what's going on, but I pray I didn't destroy my Axon due to ESD. Anyone care to help. Could I get around this issue by purchasing ISP AVR Programmer?
Thanks for reading

When I apply power to it, the Marquee turns on and blinks so that's a good sign. Do you think its the bootloader or the AVR chip responsible for the USB to serial?

A few questions so I can narrow the problem and help you fix it:
- Does it still work on the laptop?
- Did you program with the USB bootloader before?
- Did you ever plug anything into the pins '3.3V OUT'? (even by accident)
- Does USB work when nothing else is plugged into the Axon II?
- Did your laptop/PC give you any USB errors?
- What is your battery voltage?
- When you 'wheeled it over', what specifically does that mean? (a serious question)
- What devices are attached to your robot, and to what pins?
Go to:
Control Panel -> System -> Hardware (tab) -> Device Manager (button)
What do you see for USB?
(this assumes you have XP, but may be a little different depending on your OS)

Yeap. Although, this could be a sign of other problems. Plus, the USB is a must-have for debugging code so I'd rather you have that working anyway :P
ESD should not be a problem.

No. The computer would recognize the connection, but I did not ever upload a program because I cad an incompatible version of windows with the fboot GUI

12v

I pulled my robot (100 lbs) along a carpeted surface to my desktop

Here is my prj file where you can see the connections https://docs.google.com/file/d/0B83RdnxAI6xvMF95QUlETDM5ZTQ/edit

Nothing happens. No recognition of any new hardware when plugged into USB

Ahh I hope its a quick fix because I have science fair coming up. :P
I ordered a hardware programmer just in case (plus I'll probably need it in the future).

Where did you plug the 12V into? Are you using single or dual power mode?

I seem unable to download this file . . . is it public? Can you attach it here?

Ok, let's see if you can still program the MCU so we can narrow the problem down a bit.
