That's the time you realize you've been working on something for too long. Got some days to rest and now I have output!. Thanks a lot!

Well, for the Input going on even numbers got to identify my inputs having them outputted to the USB. The outputs couldn't get any sound out, I have data comming out from the OUT1A but nothing comes out from the analog outputs of the PCM. Here's...

Yeah, at least that was not that much of a deal. I'm connecting DIN1 of the PCM to OUT1A (pin 7) of the teensy and DOUT1 to IN1 (pin 8) of the teensy, using AudioInputTDM and AudioOutputTDM objects but cannot see anything on the output with a...

Last update, got to the point the Teensy can see the PCM. I had an external analog reference, took it out and used the VREFAD as reference and got the SDA/SCL lines up to the right voltages. After that I figured out I had another I2C device on...

VThanks, I'm getting 5v on AREFAD1, 0v on VREFAD2, 2.5V on VCOMAD and 0V on VCOMDA. The 2.5v comes from the reference of the analog part on the input, but the out is decoupled so 0V reference I think.

Well, there's something that's pulling the SDA/SCL lines down on the PCM. I got low voltage readings on those pins, on a board that have the PCM removed voltages are normal so no issues with the routing of those lines. Even without the Teensy...

Yes, I did reset the codec, placed AudioInputTDM / AudioOutputTDM objects. I get noise on the outputs, if I change the address with setAddress the output varies, wrong address, no output, right address noise (a lot). Here's a snippet of the code...

I built a board using the schematic placed here and I can't make the teensy to recognize the pcm. Ran an I2C scanner and got a Unknown error at 0xYY (all the addresses that is scanning). Set Mode directly to digital ground for I2C as the...

Hello everyone! I just wanted to share the Teensy 4.1–based Italian learning device. It includes all 64 levels from the original web app https://onda-sfasata.netlify.app/ The firmware was built using the Gemini 3 Flash Preview model in Google AI...

Did you considered to switch to the micromod form-factor? You just route the d+/d- from there and place whatever usb type connector you like cleanly

All, You may be aware of my FlickerFree library that lets you print text to a TFT LCD and avoids annoying text flickering upon updates. Hot off the press is an updated version that now supports drawing text with RIGHT justification for both...

Awesome, is your teensyUSBHost class public?

I have to try this, I'm using a micromod with a USB-C connector and been thinking about using it as a host as well so, this can be super useful. the variable usb_configuration comes from cores or somewhere else on your code?

Happens with all sorts of different codes, custom code, simple, complex, blink, etc. Yes I'm using all the time Serial + MIDI + Audio, didn't tried with other USB settings because that's my main use. That's why I was pointing directly to the new...

Hey folks, I recently updated the Arduino IDE to the 2.3.7 version and came with some issues with Teensy 4.1. Some times after you upload a new sketch the IDE stops recognizing the Teensy 4.1 port, it's still alive because when you hit the...
