Hey DD4WH, I answered your question over in the new project thread here: https://forum.pjrc.com/index.php?threads/t-dsp-open-source-modular-audio-platform-for-teensy-4-1-diy-audio-interface-digital-mixer-synthesizer.77722/post-367098 I also...

I'm going to answer here for a question in another thread. Hello DD4WH, The Audio Shield Adaptor schematic is a bit sloppy because of the way I designed this project. I started with the main "T-DSP Core" schematic and ripped out parts until I...

Hey everyone, I have an update! I ordered a set of 5 prototypes of the audio shield adaptor and TAC5212 modules. Built one, fired up Claude Code and referenced all the drivers we had accumulated. As I imagined, AI augmentation made this process...

@PaulStoffregen have you considered merging it?

During the (very long) Teensyduino 1.60 beta this was all still a bit bleeding edge, so there’s been no PR to date. However, I’m pretty sure most of the gremlins are out, and it’s PR-worthy. It would be great if the Teensyduino 1.61 campaign...

Thank would be awesome! I'm watching this thread just for this exact reason.

Hey everyone, I've been working on an open-source hardware platform called T-DSP built around the Teensy 4.1, and this community has been a huge resource along the way. Building serious desktop or rack-mounted audio gear from scratch is hard...

@DD4WH No worries! I've been toying with these concepts for years and have kept many of my ideas close to the chest. I've already built a test module with PDM (with help from @h4yn0nnym0u5e), so I had a lot of the pieces in place and was able...

@DD4WH I mocked up a T-DSP Mic Array Module that should cover your use case. The design uses two TAC5212 codec modules: • TAC5212 #1: 4 PDM mics (2 per data line via SELECT pin) • TAC5212 #2: 2 PDM mics + 2 Knowles SPM0687LR5H-1 analog MEMS...

Yes the TAC5212 does "up to 4 pulse density modulation (PDM) digital microphone interface with a high-performance decimation filter" as specified in the datasheet. I am not aware of a driver for that. Good luck!

Hello @DD4WH, In addition to the driver here provided by @houtson, @h4yn0nnym0u5e and I had worked on a driver and we got basic functionality working. He has a sample board. Also, I have tests for midi, led, spdif, usb, tdm, i2s, etc. It could...

Quick update. The first backplane is now up as well: https://github.com/t-dsp/t-dsp_desktop_pro This is the development platform I mentioned. It's an all-out development platform for pro audio with everything you need to get started with...

Hey everyone, I've been working with this chip family for a while now. In fact, I've been designing an ecosystem that I hope will bring creativity and joy to musicians and tinkerers alike. It started as a digital audio mixer, and it's grown from...
