Ok... very weird here, I tried another Teensy and that didn't show up either. I rebooted OSX one more time and now it seems to be working on both boards. I rebooted yesterday when I first had the issue and that didn't solve it.... Not sure what was going on but I appreciate your quick replies...

Interesting.... the window doesn't respond when I press the button on the board. I will try the other version of Arduino tonight, I'll also try a different Teensy.

Here is my screenshot. As you can see, no serial devices are found. However the IDE does upload code the Teensy without an issue.

Yup, I checked that and it was already set to Serial. Phil

Hi, I am new to Teesny and I can't seem to get the serial monitor to work. My code uploads ok but when I try and launch the serial monitor from the Arduino IDE I get the error: Arduino: 1.8.3 (Mac OS X), TD: 1.39, Board: "Teensy 3.6, Serial, 180 MHz, Faster, US English" No serial port...

Are there any examples for reading files from an SD card on Teensy 3.6 ? I can't seem to fin any that are specific to that board. Cheers. Phil

Hi, I'm wanting to make a PoV display that will show low-res video / animation. I'm hoping to use 144 LED / meter APA102 LEDs and thought a Teensy could work well. There are lots of tutorials out there for POV using static images but I really want to see motion. Ideally a standalone...

Great, I'll give this a go tomorrow. For now I'm just glad it's working.... Still unsure why my method of waiting 200ms before looking again didn't work but I can live with that :-) Cheers. Phil

Wow... This seems to be working..... HUGE thanks.... I just need to dial the numbers in now.... Phewww. Cheers, Phil

@defragster, I tried your code and got 10 beats detected when I should only get 6. Below is the code I used, I implemented it on the code that used the SD card. Cheers Phil #include <Audio.h> #include <Wire.h> #include <SPI.h> #include <SD.h> #include <SerialFlash.h> // GUItool: begin...

@defragster, I didn't try that as I am a little confused by the solution. I will see if I can figure you method out using the code snippet you provided. Cheers. Phil

Hey Paul, I modified the code to read the .wav file from the SD card and still get the issue. You will see if you run the code and have "heart.wav" on your SD card that it counts 9 beats when in reality there are only 6 in the file. Currently the delay is set to 200ms which should be plenty of...

Thanks Paul, here is the test wav file, it's only 6 beats long. https://www.dropbox.com/s/y72a2or3bx11bu3/6%20Beats.wav?dl=0 @Frank, the audio is a human heart beat.

Hi, I'm using the audio peek function to do beat detection and i am getting a false read. Basically I want to blink an LED every other beat so I detect the beats and then use case: to either turn on the LED or ignore the beat. The sounds I am using as my test has a beat of around 180ms then a...

Hi, i'm totally new to Teensy but have done some projects with Arduino. I want to do some simple beat detection and am wondering if I need the Audio Adapter. http://www.pjrc.com/store/teensy3_audio.html The adapter looks amazing but seem overkill if all i want to do is detect a beat and blink...
