Using a Pi4 as a keyboard emulator

• Pico-PIO-USB

  13 1,173 6.0 C

  USB host/device implementation using PIO of raspberry pi pico (RP2040).

However, not so many microcontrollers can easily do USB keyboard input (host) and output (device) at the same time, if that's what you need. You could look at the Teensy 4 or Teensy 4.1 for example. There might be other Arduino-compatible boards that can do it, I'm not sure which. Apparently it's also possible on the Pi Pico with this project: sekigon-gonnoc/Pico-PIO-USB: USB host/device implementation using PIO of raspberry pi pico (RP2040). But that's a bit of an advanced hack, and I can't tell you how well it works.

Have you tried using a different cable? A few months ago I wrote a similar program and someone experienced the same issue and it turned out to be the cable.
