Hello all,
Not my first project, but my first post!
I am building a USB controller for Eliteangerous again, using a Teensy 3.2 and some illuminated buttons.
The first one i made was a grand success given the fact id never built a thing like that.
Now the next ones are beeing built, (2 of the same, one for me, one for my wingman) and testing is very positive up until now.
But today, suddenly, it seems the Teensy decided it needed a break, and possibly broke.
I have connected the pushbuttons into a matrix using ports 17-18 for columns, and 0-1-2-3-4-5 for the rows.
Then i have a Step-up-module connectec to AGND and VUSB ports, which power the LED's in the pushbuttons.
On port 0 i put a resistor because otherwise the matrix disbehaves.
This whole setup is still working after 2 years in my original controller and seemed to work in the new one while testing.
Same usb cable in the Teensy, same port on laptop, but now, when i plug in the controller, the pushbuttons light up for a few seconds, then the LED's start to dim until the eventually go out after a few more seconds.
Time to measure:
The cable is supplying a steady 5-ish volts, but measuring VUSB and AGND, i only measure 1.6V // on GND and the 3.3V, i only measure about 0.06V
Long story short: is the Teensy dead/dying, or just trying to wind me up? (that last one was retorical cause it winds me up.. it worked fine, now it doesnt)
Since this im building 2 of these, it was already annoying one Teensy was DOA, so id be pretty puzzled if this one just died on me too.
It doesnt register in the list of USB controllers in windows and doesnt make the "USB connected" sound. The new Teensy i just unpacked and programmed does..
Please does anyone have an idea?
Id be ok with it IF i have a dead Teensy but i dont wan to repeat this when i again order a new one
Many thanks in advance!
