6 sourcesAre you already using TinyUSB? The examples are still pretty involved but it got me 95% of the way to a wireless USB game controller: https://github.com/hathach/tinyusb/blob/master/examples/devi...
In ESP32 Buyer’s Guide: Different Chips, Firmware, SensorsI've used TinyUSB to turn a Raspberry Pi 2040 (the very cheap microcontroller) into a USB keyboard that you plug your morse key into and send morse which the RPI 2040 converts into key presses and sends to the computer.
TinyUSB was very easy to use. It was my first foray into USB devices and adapting the example code was straight forward.
I wrote the code in C but I could have done it in python also but I didn't as you need ms accuracy for decoding morse code and I wasn't sure it would be fast enough.
There are examples for pretty much any usb peripheral you can think of here: https://github.com/hathach/tinyusb/tree/master/examples/devi...
In TinyUSB: Open-source cross-platform USB Host/Device stack for embedded systemsThis seems like a really great project; it's well-designed and supports quite a variety of different MCUs (although host mode seems to be "not implemented" in anything except the rPi).
I wonder how much work it would be to create a no_std sys crate to use this from a rust context. (I see some interest from Tock users in the GitHub issue discussions.)
The github repo for the TinyUSB project: https://github.com/hathach/tinyusb
EDIT:
I spoke too soon, there's already a tinyusb-sys crate here [0]!

3 points · Open discussionYes, Arduino, Raspberry Pi, and ESP8266 are the best "cheap MCUs" for personal use, quick shipping, good documentation, for a one-off USB keyboard.
For the RPi Pico specifically, the TinyUSB driver is the way to go. This also supports USB host (plugging a keyboard into the Pico), but that didn't support the mouse scrollwheel when I tried.

If you're interested in larger-scale manufacturing, and are willing to invest more time and effort in once-off R&D to reduce the per-unit cost, then there's a lot more options of other MCUs (e.g. PIC, Cypress, STM32).

Miro Samek also has a great series of lectures (which I learned about in the same Embedded Online Conference), which then levels up from an Arduino-style "superloop" to an RTOS, Active Object design pattern, and beyond.
