    Thanks, I wouldn't have stumbled upon this by myself probably.
    Funny thing is that my program worked only WITH usb connection. Also I already have software SPI.
    Still haven't looked further in my...

    In maybe a week I'll try to downgrade my FastLED version. Maybe it will resolve problem with required usb connection. Don't know how but maybe)

    Not at all... Only thing I edited in libraries - added printf() to Serial sometime ago.
  4. Not sure which of my problems you are having, but...

    Not sure which of my problems you are having, but try forcing software SPI implementation in FastLED. Using non-SPI pins should give same results.

    I discovered that when I connect my battery-powered Teensy to Mac with usb cable WITH CUT RED WIRE, it works fine.

    I commented out any calls to Serial and don't have infinite loop in setup()...

    Hi Paul!
    Actually I have two different battery holders for Teensy and LEDs.

    I was able to drive leds from 3.6V, but my setup was hanging up anyway.
    I am at music festival and there is no logic shifter around, BUT forcing software SPI fixed the problem!

    All good but now I...

    Yeah, I have found in Adafruit Dotstar (their name for apa102) guide that data and clock should be 5v too.
    Thank you very much for pointing this out!

    Hi!

    I do not have a SD card indeed and have currently 9 leds.
    Teensy and leds are powered from two different battery holders which have 4.5 and 4.8V voltage.
    Clock and data pins are connected...

    Forgot to mention that I have 220uF capacitor in between 5V and ground in LED power line (will replace it to 1500uF today) and 440 Ohm resistor (220+220 actually) in between pin 7 and LED data pad....
  12. Teensy hangs up after few manipulations with LEDs

    Hi!

    I have a Teensy 3.2 with soldered Audio board (Teensy is atop); other connections I have:

    to MIC and GND pins of audio board soldered pins, then wires, then audio jack
    to 7 and 13 pins...
  13. Yes! I soldered audio jack, inserted microphone...

    Yes! I soldered audio jack, inserted microphone in and it works!
    And pretty well :-)

    That is actually so. I'm just gradually testing that my soldering works, not building a tutorial.


    Excellent! Thought about this explanation but in my case it is better to double check :D

    Oh. You are right, I thought that simply inserting them is enough for prototyping.
    Thanks!

    Can't get Part 1 02 of Audio tutorial to work

    I don't have Audio tutorial parts actually but I was hoping to get Beeps in serial monitor just to see that something works. But there is nothing.
    Basically I just connected Audio board and Teensy...

    Maybe I can solder microphone audio jack directly to MIC+GND pins and it will work?

    Well, I had to order Teensy from another store and they didn't have this mic.
    And then I found that for most of the mics I could buy near me (I'm outside of the USA) I can't even find datasheet....

    Thanks for your reply.

    Oh. So to connect some external microphone I will have to solder appropriate jack?

    Hello again.

    Does 3.5" input jack on Audio board have "Plug in Power"? It is required for some external microphones.
    Also it may be useful to know - is this jack wired OMTP way or CTIA / AHJ way?
  24. Oh. Not so promising then! I will follow your...

    Oh. Not so promising then!

    I will follow your advice. So, Teensy, Audio board, two 14x1-D pins and microphone?
