I have been using the Axon as a data collection system for my son's science fair project. Unfortunately this morning he plugged the battery into the 3.3V output port, which fried the USB connection. I have a programmer, so I was able to reprogram the Axon. I have made several attempts to use one of the other serial ports for output at several different baud rates from 2400 - 38400. Unfortunately, I only get gibberish out of hyperterminal. I have already tried adjusting the baud rate on hyperterminal without success (to values other than that configure for the Axon). I have tried this through a Prolific USB to serial converter on several computers as well as directly to the serial port on an old Windows 98 laptop with the same results. The serial output is repeatable, just not decipherable.
When the power was applied to the 3.3 V pins, what else could have been damaged?
Is it possible to get the CP102 chip replaced, or am I SOL?
Any ideas on how to get some serial communication working so that I can pull data off the Axon?
