Qemu supports rp2040 emulation but sadly it dosent support i2c devices so sadly i can only show mockups now

Firmware features

• Typing reactive bongo cat animation
• PC now playing music and hw stats
• Volume control with visual feedback on the oled if its connected to the pc compenion app

Planned Features

• RGB Lighting Integration: Control the WS2812B underglow modes directly from the MonkeyOS OLED menu!
• Playable OLED Games: Adding simple mini-games like Dino Jump or Pong that you can play using the rotary encoder and keys.
• Macro Layer Switching: Switch the functionality of the 9 keys on-the-fly directly from the OLED screen.

Also sorry about the low project wokatime, I couldnt make the kicad plugin work with kicad 10, so it didnt track my time doing the pcb design, but like a lot of pain went into cause kicad is kinda hard to deal with it tbh I hope it will meet all the criteria

The firmware is really basic, but i will add more when i will get the pcb and assemble it.
