Random keyboard imputs read via COM/UART

Post by sciguy14 »

I'm building two wavebubbles, one is just about working, this one is having a small program. I just ran the test_uart code, and it worked fine displaying the alphabet. I then reprogrammed without the test code and tried to enter the serial interface. However, it seems to be reading nonexistant keyboard presses. This causes it to give tell me "Bad Command" about 6 times before it just craps out. The keys are different every time, and it prevents me from programming the frequencies because it freezes the menu system!

Would the USB chip be causing this? ...The uart test worked fine...

Ideas?

Thanks!
Jeremy

Could be a dry solder joint.

It was. I re-soldered the USB connector today and it fixed it. Thanks
