Rich, Thanks for your interest. Simple, there's a third sheet to the schematic! The circuits for IC3&4 are identical to 1&2, so I didn't include page 3 for the purposes of the discussion needed at that point. It turned out that it was a code...

@palmerr Looking forward to see your continued progress on this project. Question: In the schematic you posted (Rev C (A Prod)), There are two sheets. There is an IC1 and IC2, but I do not see IC3, IC4 from the JPG image of the PCB. Am I...

@h4yn0nnym0u5e You are correct, that change in platform.txt got me past that compile issue. Unfortunately, it led to new compile issues. So I decided to uninstall version 2.X.X of the Arduino IDE and use the version you are using, 1.8.19. This...

I wasn't sure of the exact path it was looking for, with the mix of backslashes and slashes. But the path does not appear to exist. Here is a screenshot of my directory structure:

An additional note: I only see this error after I implement the changes from @alex6679 repo linked below, and attempt to verify my new code using the 8 wide USB input: repo

Thank you @h4yn0nnym0u5e I re-installed the arduino IDE and Teensyduino according to the link you provided. I also turned on verbose compiler output. Here is the error I continue to receive: FQBN: teensy:avr:teensy40 Using board 'teensy40'...

Hello, I am hoping one of you can help be get past a roadblock: @alex6679 @houtson @h4yn0nnym0u5e I am using the CS42448 board from aliexpress with teensy 4.0. I used the github provided by @alex6679 to make the required changes to: -...

@h4yn0nnym0u5e Thank you. That is very helpful.

@h4yn0nnym0u5e I have reviewed the entire thread and the repo. I noticed that the readme in the repo states: "In order to use it, copy the files of 'changedCorefiles' into cores/Teensy4 and replace the original files." I also noticed that you...

Thank you for the response @h4yn0nnym0u5e . Guidance from experienced members like yourself is much appreciated. I will focus on the thread you referenced and check out the repo to implement the 8-wide USB input.

Thank you for the response @houtson . It's very helpful to receive guidance from experienced members, to confirm I'm not completely off the rails. :) Much appreciated. I will focus on the thread you referenced, and try to implement the changes...

@MarkT @AntiLoop @PaulStoffregen I ran the example Audio/HardwareTesting/WaveformsTDM16 successfully. All 8 outputs are working. But this plays generated waveforms. To accomplish making this Teensy 4.0/CS42448 act as an 8 channel USB Audio...

@MarkT @AntiLoop Hello, perhaps one of you might help me understand how to make use of the Audio System Design Tool. I created the layout that @houtson shared. I get the confirmation message "configured CS42448" in Serial Monitor. But I don't...

Thank you for sharing this great information! As I am new to this forum, please forgive this simple question. I would like to use the Audio System Design Tool to program the Teensy to be a USB Audio device, with 8 output channels. I will write...

Hello All, As a newb, just wondering how one might leverage the great work done here. @h4yn0nnym0u5e @alex6679 For example, what hardware is required to make use of 8 output channels? Is it hardware that is available at PJRC.com? Or must one...
