  1. Quick answer: nope. I'm working on an Arduino...

    Quick answer: nope. I'm working on an Arduino Zero smaller clone and on an interactive badge based on it. It is going to take some time but I didn't forget about this, that's for sure.

    Hi people, I took the project back on track and I'm working on integrating it with the Audio Library (FINALLY!). It's gonna take some time due to the tremendous amount of work to do:

    - USB stuff...
  3. Hey guys, I got the Teensy to transmit packets...

    Hey guys, I got the Teensy to transmit packets greather than 64 bytes, in fact I got it to stream 192 bytes per packet; I also got it to use more than 8 bytes for each word in the buffer. Paul, I...

    That message was way early in development stage, I really had no idea of what I was talking about! :D
    USB device implementation may not be basic at all, especially when dealing with audio, and with...

    I'm thinking of a restyling of the current USB memory management system, to support 1023 bytes packets. I've found two lines of code, lines 675 and 684 of usb_dev.c that look like this:

  6. Okay guys, I decided to put everyhing I've done...

    Okay guys, I decided to put everyhing I've done until now on my GitHub account. The only step I've made since the last update is that I've modified usb_dev.c so that it doesn't toggle between Data0...
  7. Just a little update: I added a startup function...

    Just a little update: I added a startup function that allocates a usb packet, and a callback function that whenever there's a SOF writes 16 bytes of nothing in the packet and sends it. I can record...

    Paul, I got it to "work"; I really don't know why or how, but the Microsoft calculator always gets my calculations off by one when using the hex calculator, so I had a bad descriptor size, my fault...

    I started debugging using an Arduino as a Serial to USB converter, to better understand what's going on. I noticed that using a preconfigured USB, like Serial or Midi or whatever, the Teensy receives...

    Little extra @PaulStoffregen: there is a mispelled define in usb_desc.h at line 43, it says ENDPOINT_TRANSIMIT , instead of TRANSMIT :)

    This thing is becoming more and more painful each day... I found out that Microsoft does not give driver support for USB Audio 2.0, unless you specifically write a WDM driver. I reconfigured the...

    Paul, I'm talking about the Teensy 3.0; I'm sorry but from your examples it is almost impossible to understand what's going on, and I really had no idea about the fact that the API you present in...
  13. I need some help about the use of endpoint 0 on...

    I need some help about the use of endpoint 0 on the Teensy; I can't quite understand the usb_dev.c file, at least some part of it; I'd like to know how can I handle a class-specific request; I mean,...
  14. Hey guys, I've found the problem: an USB Audio...

    Hey guys, I've found the problem: an USB Audio Device receives requests from the host via endpoint 0, and the requests types are class-specific, so I have to handle every request by adding stuff to...

    Hello there, I'm having a difficult time trying to setup an USB Audio core type for the Teensy. I'm currently working on Teensy 3.0, and I want it to enumerate as an USB Audio Device. I started from...
