Teensy 3.2 hack project

[marcavius]

I dont think its applying voltage? I still dont understand.

 

[tonton81]

if teensy isnt detected (you can confirm its being disconnected via USB error/disconnected state)

you have a short somewhere, most likely teensy shuts down due to a short to protect itself (most of the time)

what happens if you temporarily dont set pin13 as an output? does teensy still disconnect after reset?

 

[marcavius]

How do I check if something is forcing power? Or ground?

 

[marcavius]

What does that mean, change it to INPUT from pinmode?

 

[tonton81]

yes, to see if the disconnections stop

 

[marcavius]

I mean it just makes the disconnect sound, now.

 

[tonton81]

just a disconnect? you cant have a disconnect without a connect

can you make a diagram of where the connections go, and what those connections do?

 

[marcavius]

I dont really have time until next week. I may just give up. Thanks for yalls help. Goodnight.

Remove your wire from pin 13.

Then upload the Blink example again. The orange LED on Teensy should blink.

 

[marcavius]

Ill try this.

 

[marcavius]

It has no light at all, now

 

[tonton81]

did you put pinMode back to OUTPUT?

 

[marcavius]

yep, i did

 

[marcavius]

yep, i did, i resterted arudrinow and redid the expample too

 

[tonton81]

i’d refer to the 3 items on post #14 if your led is not working when nothing is attached to it using blink example

[marcavius]

kay yeah. Bunk project. Thanks anyway yall

I cut all my wires. I probably just broke it somehow.

Its not blinking with absolutely nothing connected except USB

Can you connect a voltmeter to pin 13? The black lead connects to GND and the red lead to pin 13. Set the meter to measure DC volts. If your meter has more than one DC volts setting, choose the lowest voltage range that is more than 3.3V. For example, if you have 2V and 20V, then set it to the 20V range.

Open File > Examples > 01.Basics > Blink. After you upload this Blink program, the orange LED should blink and you should see the DC voltage change back and forth from 0 to 3.3V.

If the upload works, but no blink and no voltage change, then the board was likely damaged.

Yep I broke it.

If the board is still able to upload, perhaps some of the other pins still work? You can change the pin number in the Blink example, upload again, and check the pin with your voltmeter. But the orange LED is only on pin 13, so you will only be able to check with the voltmeter.

I'm going to try using a new teensy.
