Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

August 2022 What Are You Working On?
Still working on my mechanical keyboard firmware. It's nearly working correctly with layer support. Still need to debug some minor glitches.

July 2022 What Are You Working On?
Finally got to work again on my Ada firmware (after being on-and-off for several months) for my custom built mechanical keyboard, I've finally reached a state where I can focus on features more than debugging low-level USB issues (first time looking deep into USB and got to write the driver for stm32f072).

May 2022 What Are You Working On?
I'm writing a firmware in pure Ada for my custom keyboard (https://github.com/dkm/pouetpouet-board). First step is to port existing HAL-implem/Drivers from Ada_Driver_Library to stm32f0, which is already in looking good: GPIO, UART and USB (enumeration is working, that's a good step) are in good shape. Then I'll probably have to read a bit more how other keyboard firmware are really working under the hood.

2023 Jun 19 Stickied -FAQ- & -HELPDESK- thread - Boot problems? Power supply problems? Display problems? Networking problems? Need ideas? Get help with these and other questions!
I know that I can have multiple ports using https://github.com/sekigon-gonnoc/Pico-PIO-USB, but I wanted to know if I could make one port a device and the other a host at the same time using the given PIOs and state machines.

usb_embedded + RP2040
I think a PIO based USB driver is a better approach, but someone needs to do the work of porting that to Ada.

Recommend MCU with dual USB - one host and one device IF?
That would be Pico-PIO-USB library or some people combine two Pico boards (or one board with two RP2040 MCUs).

USB on pi pico
If you need both device and host interfaces at the same time, then you can either use Pico-PIO-USB library or combine two Pico boards (or one board with two RP2040 MCUs).

Using a Pi4 as a keyboard emulator
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.

RP2040: Okay to use USB type A male-to-male for programming?
Maybe you could use something like this: https://github.com/sekigon-gonnoc/Pico-PIO-USB

Summoning the ergo experts for guidance
you should check out https://github.com/sekigon-gonnoc/Pico-PIO-USB for someone that has implemented USB chaining with rp2040. unfortunately it uses up both PIOs.

USB HOST alternative!
The pico just seems to be a flexible cheap option for USB applications. An example https://github.com/sekigon-gonnoc/Pico-PIO-USB

reading a usb keyboard input
Highly experimental for advanced users. Adds a second USB port to Pi Pico using the PIO controller so the pico can connect to a PC and keyboard at the same time. https://github.com/sekigon-gonnoc/Pico-PIO-USB

Using the second USB port on a split keyboard as a passthrough for a mouse, is it possible with QMK?
watch the video to see this non-qmk firmware for the Rasberry pi Pico used to daisy chain devices with fixed device and host ports https://github.com/sekigon-gonnoc/Pico-PIO-USB
What are some alternatives?
When comparing pouetpouet-board and Pico-PIO-USB you can also consider the following projects:
Ada_Drivers_Library - Ada source code and complete sample GNAT projects for selected bare-board platforms supported by GNAT.
tmk_keyboard - Keyboard firmwares for Atmel AVR and Cortex-M
