    How to switch between 2 different programs (different HEX) on Teensy 4/4.1?

    I wish I could do this, but I can't change the AUDIO_BLOCK_SAMPLES on the fly.

    How to switch between 2 different programs (different HEX) on Teensy 4/4.1?

    Hi everyone, I'm trying to figure out how to switch between 2 programs on the Teensy 4/4.1. I would like to have an initial program that will read the state of a button when started that will redirect to 2 different programs. This same question was posted some years ago for Teensy 3.6, and I...

    Flip Teensy USB host pads for USB programming

    Hi everyone! I was wondering if it is possible to flip USB1 with USB2 of the NXP chip used in Teensy 4 via code. I imagined this is possible with a new bootloader, but is there any code to overwrite this? This would allow me to connect another USB programming socket to those pads at the back of...

    USB interface for multi channel outputs, not just stereo

    I made a custom board with the CS42448 for the same purpose and I'm also stuck at the same place as you. I managed to show more outputs in Windows too, but that was it. I still have hope this will be possible soon with Teensy. Understanding those bitwise operations would be a good new step and...

    Bass guitar -> USB sound project questions

    The 50ms update is only an example. If you are not running any DSP through Teensy, I guess the only reason you need a Teensy (and not any other microcontroller board) will be for the USB Audio functionality. It is important to plan well how you will be switching your multiple output signals...

    Quad channel output on Teensy 3.6

    That's great Paul. I will try VA to the battery first, good idea! Then I will do another test with 3.3V and if the regulator can't cope with it I will use another one externally. Thanks!

    Quad channel output on Teensy 3.6

    Hi Paul and everyone. I'm designing a similar board to use Teensy with the CS42448 and was wondering if it'd be possible to use 3.3V for VA? I need to make it battery-powered (lithium 3.7-4.2V) so I was planning to just have a battery connected to VIN and use the regulated 3.3V to power all the...
