Daisy

Rust no_std, embedded_hal board support package for the Electro-Smith Daisy platform.

• Documentation
• Crate (crates.io)
• Repository (github.com)

Supported boards

Currently this library supports following boards:

• Daisy Seed (codec AK4556), seed
• Daisy Seed 1.1 (codec WM8731), seed_1_1
• Daisy Seed 1.2 (codec PCM3060), seed_1_2
• Daisy Patch SM (codec PCM3060), patch_sm

Select the board by using its respective feature.

Flashing an example

Using DFU. Connect using a sigle USB cable, click BOOT+RESET before flashing:

make flash-dfu WHAT=blinky BOARD=seed_1_1

Using probe-rs. This requires ST-Link probe, but provides additional logs and panic messages:

make flash WHAT=blinky BOARD=seed_1_1

Using Daisy Bootloader. This extends the maximum firmware capacity. You can find a guide with an example under examples/bootloader.

Sampling rate

By default, the audio sampling rate is set to 48 kHz. This can be increased to 96 kHz by enabling the sampling_rate_96khz feature.

Block length

By default, the audio block length is 32 frames. This can be increased to 64 by enabling the block_length_64 feature.

API stability

I am still trying to figure out a good API for the project. Expect it to change. To mitigate breakage of your code on library update, use macros defined under board.rs to initialize resources whenever possible.

HAL compatibility

This library is closely tied to stm32h7xx-hal. Make sure to use compatible versions in your Cargo.toml.

Razor

• This library aims to abstract all peripherals that are available on Daisy.
• This library will not abstract anything that is not on Daisy, e.g. pots, SD cards, MIDI, ...
