Catalina

Catalina is an audio and music processing ecosystem designed for embedded ARM Cortex devices. This includes the core DSP and instrument framework, example instruments, and a board support framework for the Catalina hardware modules, carriers and kits.

Features

Firstly, there are some core features that enable shadowing of the other catalina- crates from the mono-repo into this base crate:

• engine - The core DSP and instrument framework build building audio processing chains, sequencers, synths, etc. Enabled by default.
• instruments - Basic instruments to serve as the base or examples for building custom instruments.
• bsp - The board support packages for Catalina hardware. Requires other board-specific features such as mini-v1 to enable board support for a specific hardware platform.

These become available as shadowed imports via catalina::<name>.

One of these base features needs to be enabled for the catalina crate to provide anything.

And then there are several fairly standard features that are common across embedded Rust packages:

• std - Disabled by default, enables std library support instead of no_std core.
• alloc - Enables use of datastructures that require allocation. When disabled, heapless datastructures are used instead.
• defmt or log to support either as the logging framework for instrumentation. Also adds the defmt::Format macro to structs for logging.
• serde - Enables serde serializing and deserializing on structs and enums.
