That's good to hear! It's still on my to do list to work through this (and the multiple MPU sketch) and post it in some public format so people can find it easily. Just not enough hours in the day.

What teensy are you using? What pins? Do you have anything else wired to the teensy? If so you might need to tell the code to look for it at 0x69 instead of 0x68. Have you tried not using the resistor? Depending on the breakout board you do not need a resistor.

I just went through it side by side with my code, which is working, but also has a bunch of other things going on. It looks okay. I forgot, however, that Kris used a separate display unit to output the data. I don't have any of that. I'm attaching code I edited that substituted the display...

By false reading, do you mean no readings like the person above? Can you post the code you're using? The examples on his github page should be fairly plug and play. If you need to use 0x69, there's a commented line you need to change, but otherwise, it should ouput numbers out of the box.

I've experience similar behavior to this using jrowberg's mpu-6050 library. It was one of multiple issues I was having with the library, and I ended up switching to use Kris Winer's library for my project. You might want to give that test ride and see if it works any better. Something to...

I've run into a couple of issues while working on a project. Neither of these are getting in the way of what I'm working on, but I felt like I should share them. 1) When importing audio connections into the Design Tool, the connections do not import when I use the Filter object connected to...

So, if I'm looking at that image correctly, the waveform objects in the gui image above are actually PWM or FM sines but labelled waveform? Signal modulation would be fantastic, but I have to say I've been enjoying the limitations the current set up has.

Paul posted the build on twitter: https://dorkbotpdx.org/node/1274 This picture caught my attention: Does anyone know how they were able to get signal into the waveforms using the audio design tool?

Yes. I was able to get this to work. I was looking to use the DMP with multiple units, and I was unable to get the i2cdevlib dmp sketch work with multiple units and remain stable. See the first sketch I posted at the top of the thread. If you have an idea for that, I'm all ears. Or, if you have...

Well, I took pictures, but they came out blurry, and now I'm at work. Still, the sensors provide logical information when I've run the sketch in the past. It just crashes, so I believe its wired correctly. I like the idea of using address switching because I could in theory scale this to more...

Sorry, this is what I get for waiting until I had run out of steam before posting. To answer your questions: teensy 3.2, and I can set the addresses by wiring the breakout boards to 3.3v and ground. They are recognized correctly by an I2C scanner. I'll try to take a pic before work in the...

This week I hit a huge speed bump in a project I've been working on, and I'm not sure if what I'm even trying to do is feasible, or if I'm going about it in a totally wrong way. The project: I'd like to use a teensy + audio shield to create some interactive music. The inputs would be multiple...

Oh, sorry if it wasn't clear. I've been running the tutorial sketches because they're simple and proven to work. I did make an adjustment to Part 2-02 Mixers to test volume output, posted below: #include <Audio.h> #include <Wire.h> #include <SPI.h> #include <SD.h> #include <SerialFlash.h> //...

The pot was connected from the 3.3V out on the teensy. Running a sine out seems... fine? I just ran a few other tutorial sketches and anything involving synthesis seemed to sound correct. Having the teensy play a single SD card also seems fine. Playing 2 wav files is where I run into trouble...

I've been working on a project for a while, and I was beginning to explore how I'd interact with the teensy. I made a huge error in attaching a pot to the wrong pin. I miscounted in the wrong direction on my bread board, ran a sketch, and then messed with a pot, causing mass chaos. Not realizing...

From my post dealing with an issue getting interrupts to work:

This could be helpful, but I think its more of a documentation issue than a coding one. I really appreciate the idea of you trying to make things as seamless from one platform to another, especially as a beginner with all this. I think I would have been able to solve the problem on my own though...

Thanks! Specifying the pinMode was crucial. I also had to adapt the code to move the interrupt information to the loop section of the code. I have attached the working code with *** in the comments to what I changed from the original that I downloaded. // I2C device class (I2Cdev)...

Hello- This should be a simple answer. I've tried everything I can think of to solve it with no luck. I'm trying to go through the mpu 6050 tutorial found here. I ran it successfully with an UNO, but I want to use it in a teensy project, so I moved everything over and its not working. I'll...

Thanks Pete!

Oooh. Okay. I see that now. To be clear, I created an array of CHORUS_DELAY_LENGTH elements, but currently all of the values are zero, correct? Does the chorus populate that array with information? The reason I ask that is because I want to know if I wanted two chorus effects on two different...

Hello, I had a question regarding the chorus tool. I figured out how to make it work, but I don't know *why* it works the way I made it work, as opposed to what I tried first. I'm going to focus on the working and non-working code, with the full code at the bottom. Working Code...

(I saw the note about changing it to short in the gui notes, but I had inverted it to needing to change it from short to int. This is probably a mistake only I'll make, but I figure I should mention it here just in case anyone else stumbles on this thread in the future.

I owe you a beer! Thank you so much!!!!

Hi Pete- We managed to make one error go away! Thanks. Now I have a new error, related to being unable to call a function. I'll post the code below. It appears that the example for the fir filter in the library is built much differently than I had interpreted the gui notes on the fir filter...

Well, I don't have the exact settings saved because I typed in a new setting and it cleared, but here is the current setting, which give similar sized numbers: from to gain ripple/att act rpl 0 400 1 5db 12.19db 500 1000 0 -40db -31.81db and the output set to...

That's what I thought too, but those are definitely the numbers trigger punched out when I chose int. I figured I was confusing how I counted bit sizes. I'll mess with the tfilter site some more, though, and see if I can get it to give me numbers in a friendlier size. Thanks for pointing me...

Hi- I recently completed the Audio tutorial, and I'm really enjoying it. I want to use it (eventually) in a project involving comb filters, so I wanted to get to know how to use the fir filter. I don't have a mic connected to the set up, so I was attempting to make a sketch from scratch...
