I completely unsoldered all of the connections, resoldered the vUSB patch, yet it is still working in exactly the same way. Nothing shows on the teensy loader when pressing the button or plugging in, but the verbose connection shows exactly as above. The teensy itself seems to stop running fine...

Hey all, I have a Teensy 3.2 that is showing a strange issue. It has been programmed with "USB type: MIDI" and is running its program fine and when I plug it into my windows 10 computers it shows up as a "Teensy MIDI" in Device manager. Yet when I try to program it, nothing happens. The two...

Ah I get it. I do see people have been using it (slightly out of spec) for I2S. Anyone have thoughts on whether "raw" PDM over RS422 would work?

Thanks Frank, I like the suggestion of using a RS422-like protocol. While twisted pair I2S would give me too many lines, PDM's 2 lines (+power) seems very doable. Also as far as I understand it PDM's 6.144Mhz max data rate should fit right up in RS422's 10Mb/s max speed. I see the ADAU7118 came...

With the new Teensy coming out, I got excited about reviving an old project, but got stuck in the same thought pattern. I am curious if there are some other approaches to what I am trying? Basically I am trying to create a mixer for eight digital MEMS (PDM, I2S or TDM) microphones, each...

Getting a step further in the process, I see that putting the microphones in series will not work as I need to be able to use any number of microphones. I see two options now: 1. have one teensy receive 4 i2s microphones, process it, then transfer the sum to a second teensy over i2s, and have 3...

In my case I'll be close-micing drumheads and such, so I'm rather looking for ways to physically attenuate the sound not to reach the 117 dB SPL Acoustic Overload Point, but this I will have to do experimentally. Thanks for the clarification Paul. I am still considering some other options with...

------------------------------------ Admin Edit: ICS-52000 microphones do not appear to work well with Teensy at 44100 Hz sample rate. ------------------------------------ I'm designing something that could best be described as a digital mixer with 8 microphones and a stereo output. I came...

Thanks Paul! Amazingly quick reply! Edward, when I leave out the resistors, I'm shorting the hot and cold line of the XLR right? To avoid this, some resistors seem necessary, but how would I figure out what would be the ideal values to use? (potentially including a bit of attenuation)

I'm doing an audio project in which it would be convenient to work with as little cables as possible, and as such I started wondering if it would be possible to power the Teensy from 48V phantom power directly over the audio line? In the diagram below a made a rough sketch of what it could...

I ran a wire to ground, which seemed to ease things at least a little, though still not 100% stable behavior. Looking at this text, I learn that a mutual capacitance setup might work better for my application. I don't seem to find anyone having implemented that in Arduino; something for on my...

Just to clarify, I made a drawing:

Hey all, I'm working on a musical instrument in which I'm using the Teensy 3.2's Touch pins. I'm having some problems though keeping it calibrated in electronically busy environments. The Teensy pins are hooked up to 11 4x4cm squares of aluminium tape on the inside of a wooden bowl with about...

I'm building an instrument based on seven playable sine waves. Most things seem to work fine, yet I'm having problems getting a decent gain. I would expect that summing 7 sinewaves each at 1/7th amplitude would lead to a final peak of 1.0. This is indeed what the peak object tells me, but on my...

Thanks Working with MIDI mode is functional! Though Max cannot communicate with the device in MIDI mode. The delay doesn't change anything sadly. I guess there is a process snatching the comport unless arduino is first to connect to it. Might the be some utilities to check which process is...

My computer seems to have a strange issue with the Teensy LC, though I found a workaround, suggesting there is a solution possible. The problem is that Serial communication doesn't want to open and the Teensy does not want to program automatically, only when I press the program button. I found...

The temperature sensor is also reading 1, so it seems that all analog function is broken. Digital seems to work fine, so I'll declare this teensy to be digital only. Of course it was a project demo I was presenting to supervisors and a client on the same day... Thanks for the input! edit: I...

After transporting a prototype, my Teensy 3.1 reads '1' on every analog port, whether or not anything is connectected. I used the code below to diagnose, but I'm afraid that I have blown something... Digital and PWM operation seems fine. Does anyone have a clue what is going on? Thanks! 0=1...

Shee, as obvious and simple as that, thanks!

I get some strange behavior from analogRead in the code below, in which I can't figure out what goes wrong... Somehow every other time analogRead() is called in my loop, it just returns 0 as seen below. It has nothing to do with the frequency in which it is called and neither does...

So, Arduino gives me the errors pasted below, using the attached code, and windows tells me "USB device not recognized". (And again, when uploading a known to work sketch, all is fine again.) I'm using windows7, Arduino 1.0.4 and the latest TD version (not sure where I can derive the actual...

So after another day of dealing with the problem, I found my workaround. When the Teensy3.0 suddenly loses connection, I upload a simple, tested program with Serial in it. I have to press the button on the Teensy to make it upload. And then it reconnects and I can upload the sketch I was working...

As an electronic instruments enthusiast, I've been meaning to make a 1bit PWM DAC for some time and I finally succeeded. Most examples I found relied heavily on C(++) code which, to be frank, is still incomprehensible for me. So I made my own, using only Arduino code. I feel like my version is...

As stated on the troubleshoot page, there is no definite solution for the "Code 43" problem. What happens, is that the Teensy3.0 suddenly (after uploading a sketch) won't install as a "USB Serial" device, but as an "Unknown Device". Strange thing is that the Teensy Loader still uploads sketches...
