@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...
@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...
@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...
Yes, it's probably possibly. You would most likely program the ESP to send the data over WiFi to Teensy on a serial port pin, which could connect to any of the 8 serial ports on Teensy 4.1.
@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...
If you look at the T4.1 card, it is pretty easy to hook up both USB Host and USB Device.
The Device pins duplicate what is in the USB connector that you connect up to your PC.
So yes you can connect up the keyboard to the teensy using the...
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...
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...
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...
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...
