    How to wire keyboard controller board (four usb wires 5V, d+, d-, gnd) onto Teensy for usb input?

    @Paul @KurtE so when I google "esp32 usb device mode" it seems like the esp32 supports device mode. The hackaday link i posted above shows how usb host capabilities are added to the esp32 manually. So i get the impression that both could exist simultaneously on the esp32 but what do you two...

    How to wire keyboard controller board (four usb wires 5V, d+, d-, gnd) onto Teensy for usb input?

    @Paul @KurtE actually the newer esp32 look like they can be configured to be usb hosts. https://hackaday.com/2021/03/26/usb-comes-to-the-esp32/ wondering if I can use an esp32 alone to receive the iphone keystrokes and the physical usb keyboard keystrokes and send both to pc...

    How to wire keyboard controller board (four usb wires 5V, d+, d-, gnd) onto Teensy for usb input?

    @Paul thanks thats what a intuited based on what ive read online. Really new to all this stuff but I am trying to focus on learning only what I need for this project and so just want to identify potential hardware to start learning with/testing designs.

    How to wire keyboard controller board (four usb wires 5V, d+, d-, gnd) onto Teensy for usb input?

    @KurtE thank you, like I said I am new to microcontroller programming but based on what I read online I had the impression that the teensy could be a usb host and device. I also understand that software library is needed to make use of the data and that it is not simply received passively. The...

    How to wire keyboard controller board (four usb wires 5V, d+, d-, gnd) onto Teensy for usb input?

    Thank you for the very helpful reply! So I wanted to ask, in the video I posted above, isn't the arduino acting as both a usb host and a usb device? I am sorry if my lack of experience implied something unintended, but I am just looking for a hardware setup that can be used to make a keyboard...

    Can arduino pro mini take ps/2 and uart input and convert them to usb?

    I am trying to figure out what hardware I need in order to create the following: An old wired usb keyboard that sends data to pc through usb port, but can also receive keystrokes over wifi and send those to the pc as well. I am thinking since many older wired keyboards can fall back to ps/2, I...

    How to wire keyboard controller board (four usb wires 5V, d+, d-, gnd) onto Teensy for usb input?

    Hey so I dont understand how that is different than what I proposed. What exactly wouldn't work with what I mentioned? Keyboard -> teensy -> PC sounds like what I want to do. The teensy will sniff the keyboard usb line and send it to the PC without modifying it. The wifi microcontroller will...

    How to wire keyboard controller board (four usb wires 5V, d+, d-, gnd) onto Teensy for usb input?

    Hello, I am new to microcontroller programming/design and I am looking for a solution that will allow me to receive a usb keyboard's key input into a microcontroller which can also be setup to communicate with an esp32. \ So basically, the keyboard has wires that connect the controller board to...
