    These are good suggestions. The multiplexer is probably a must when I try expanding to 40+ i2c sensors some day. But I'm also more confident with software solutions than hardware,

  2. Hardware i2c/keyscan capabilities of teensy 4.1?

    I'm working on an audio project, and I want to get the most I can from the CPU. What I am worried about is how to better optimize my GPIO/I2C to reduce CPU overhead. I have 2 problems...

    Update:

    Switched the mac code to use blocking IO and loop over each read/write until all bytes copy, and it seems I'm getting substantially better bandwidth, up to 13*192=2496 bytes in and out per...

    I'm working on a project which involves a signal chain through multiple Teensy4's on a usb hub, so I started by testing to see if I could meet my bandwidth and latency requirements.

    I wrote a...
