Did I fry my teensy?

[nicckk]

Hi all,

I am quite new to building keyboards and electronics in general. I am trying to convert a Qume terminal keyboard to use a teensy. I looked over Soarer's WYSE converter tutorial and naively followed the pinout for the WYSE boards (I found little information online about the Qume keyboard). As a reference for the WYSE board it is: black -> gnd, red-> vcc, green -> data, yellow -> clock. I tried that and it was not working.

After poking around a bit more online I found an alternative pinout for these terminal boards that is: black -> data, red->vcc, green->clock, yellow -> gnd. Now when I use HID listen the board is recognized with ID 00 (WYSE model 85), however, nothing is displayed out when I hit keys on the board. Did I fry the teensy when I incorrectly connected the wires? Any help would be appreciated!

Thanks, Nick.

I think your teensy is fine. It just doesn't have a layout flashed into it. Just go ahead with the rest of the instructions (I'm assuming you're following instructions from somewhere) on creating a layout and flashing.

usually wiring wrong on one of these terminal conversions wont fry out the teensy, but the controller that you are connecting to.

If the controller on the keyboard fried out wouldn't there be no output at all on HID listen? HID listen still detects a keyboard is connected.

Thank you I will look into this

Most likely it would still be fine if hid is detecting it

just food for thought.

Someone may correct me but 'wrong wiring fried' usually means putting voltage where it shouldn't be, if there's no protection circuit this releases the magic smoke which breathes life into electronic things - if you've not seen/smelt that you probably didn't fry it.  Did the board definitely work before you started?

Your teensy now thinks it's a keyboard so that's not fried, but it doesn't say anything about whether it's wired up to the keyboard correctly or if the keyboard works.

Hopefully adding a layout fixes it
