README
README.mdfloppier
Floppier is an embedded Rust project targetting the Raspberry Pi Pico which allows you to play MIDI files on a series of 1 or more Floppy Disk Drives. This project is inspired by Moppy which is a similar project written in Java and C++ targetting the Arduino platform, and the almighty Floppotron.
This project differs from previous implementations by allowing you to expand to a large number of drives and plans to have support for other instruments as well such as Hard Disk Drives and Flatbed Scanners.
Project Structure
This project is organized as a Cargo workspace with the following directories:
floppier-server- A Rust program that runs on a laptop or desktop to parse a MIDI file and send MIDI events over USB to the Pico(s)floppier-client- An Embedded Rust program that receives MIDI events from the server over USB and is responsible for controlling the individual Floppy Disk Drivesfloppier-proto- A Rust library that contains shared protocol data structures which are sent in USB packetsmidi- A directory containing some sample MIDI songs and their configuration files

Questions
How big is the Drive controller master PCB?
It measures 90 × 20 mm and has 4 copper layers, 1.6 mm thick.
What parts does the Drive controller master use?
64 parts, built around the RP2040, 74AHC1G125GW, W25Q32JVUUIQ and 74HC595. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Drive controller master KiCad files?
From the wowkster/floppier repository on GitHub, at the commit this page was made from: the board is hardware/drive_controller_master/drive_controller_master.kicad_pcb and its schematic hardware/drive_controller_master/can.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Drive controller master design in my own project?
Its repository states no licence, so its author keeps all rights: ask wowkster before reusing the design.
