Hello,
I have Teensy3.2 + audio board, attached to a pcb that's been working fine for the last week or more. I was doing prototyping, uploading code to the teensy and nothing else, and then suddenly the teensy disappeared, no modem found, no lights on, no one seems to be home.
I'm 100% sure it's not been fried as they only thing powering it has been a usb lead from a computer, unless some other fatal flaw has happened whilst uploading code which I highly doubt. No voltage spikes are going to be sent from a mac usb port as then we'd all be frying teensy's.
Is there any way to troubleshoot past this guide: https://www.pjrc.com/teensy/troubleshoot.html
I'm not powering other devices, only reading buttons, pots and lighting an led, the pcb with the pots/knobs has been working perfectly.
I don't understand how it can work fine and then go kaput for no reason.
Any way I can test what could be the problem?
