neobirth/purezen

WIP port of the ZenGarden PureData audio synthesis engine to Rust

Acid house music program for the Adafruit NeoTrellis M4, powered by the PureZen music synthesis engine (a Pure Data engine targeting embedded Rust devices).

Inspired by Propellerhead ReBirth.

Status

The current code produces a working executable which can be loaded onto a NeoTrellis M4 device, however no functionality is yet in place (unless you like blinking LEDs).

Requirements

• NeoTrellis M4 Express device
• Rustup and Rust 1.31+: https://rustup.rs/
• rustup target add thumbv7em-none-eabihf
• GNU ARM Embedded Toolchain
• BOSSA (flash programming utility for Atmel's SAM microcntrollers)

Compiling

$ CARGO_INCREMENTAL=0 cargo build --release
$ cd target/thumbv7em-none-eabihf/release/
$ arm-none-eabi-objcopy -O binary neobirth neobirth.bin

Flashing the NeoTrellis M4

Press the RESET button on the back of the NeoTrellis M4 twice in rapid succession. The LED on the back will turn green.

Then run:

$ bossac -e -w -v -b -R -o 0x4000 --port=/dev/<your platform dev> neobirth.bin

Note that the --port flag for bossac varies by OS:

• Linux: /dev/ttyACM0
• macOS: /dev/tty.usbmodemNNNNNN (try ls /dev/tty.usbmodem*)

Where to start for contribution

Hi! I'd like to continue developing this project. Could you point me where to start and what's the state of it? Also, could you share your (unfinished) ideas related to the implementation of this crate? Though, I'm not sure about no-std as it's out of scope for my requirements... But I'd make a fork or something and I'd maybe continue it with no-std. Not sure until I didn't dive into the code. Anyway, I'd started from bindings for ZenGarden, but now I can spend more time on this project and would rather continue Rust implementation.

Depends on broken generic_array

This is a heads-up that this crate depends on a buggy version of generic_array that does not contain fizyk20/generic-array#89, and rust-lang/rust#71274 means that in future rustc versions this can lead to panics when using old generic_array. Would be great if you could update the dependency. :)
