USB Audio Class 2.0
|
||||||
|
|
||||||
|
This crate provides a USB Audio Class 2.0 implementation for
|
||||||
|
[usb-device](https://crates.io/crates/usb-device). It implements all
|
||||||
|
required elements of the specification, however many controls are not
|
||||||
|
implemented (e.g. mixers, effects).
|
||||||
|
|
||||||
|
Device behaviour is driven by implementing the `ClockSource` and
|
||||||
|
`AudioHandler` traits to configure the audio pipeline and source/sink data
|
||||||
|
to/from USB.
|
||||||
|
|
||||||
|
Example (creates a UAC2 device with in and out streams):
|
||||||
|
|
||||||
|
```rust
|
||||||
|
let mut audio = YourTraitImpl {...};
|
||||||
|
|
||||||
|
let config = UsbAudioClassConfig::new(usb_speed, FunctionCode::IoBox, &mut audio)
|
||||||
|
// base_id is USB entity ID, id 1 is always taken by the clock source, and each stream builds 2 entities
|
||||||
|
.with_output_config(TerminalConfig::builder().base_id(2).build())
|
||||||
|
.with_input_config(TerminalConfig::builder().base_id(4).build());
|
||||||
|
|
||||||
|
let mut uac2 = config.build(&usb_bus).unwrap();
|
||||||
|
|
||||||
|
let mut usb_dev = usbd_uac2::builder(&usb_bus, UsbVidPid(0x1209, 0x0001))
|
||||||
|
.strings(&[StringDescriptors::default()
|
||||||
|
.manufacturer("usbd_uac2")
|
||||||
|
.product("example")])
|
||||||
|
.unwrap()
|
||||||
|
.max_packet_size_0(64) // Required to be 64 on HS
|
||||||
|
.unwrap()
|
||||||
|
.build();
|
||||||
|
```
|
||||||
|
|
||||||
|
No work needs to be done in the poll loop, the class implementation will
|
||||||
|
call your trait callbacks as required, just call the usb poll as usual:
|
||||||
|
|
||||||
|
```rust
|
||||||
|
loop {
|
||||||
|
usb_dev.poll(&mut [&mut uac2]);
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|

Two example backends are provided, both based on the LPCXpresso55S28 demo board, using the onboard WM8904 DAC.
|
||||||
|
|
||||||
|
## LPC55S28 (LPCXpresso55S28)
|
||||||
|
|
||||||
|
These examples work on the
|
||||||
|
[LPCXpresso55S28](https://www.nxp.com/design/design-center/software/development-software/mcuxpresso-software-and-tools-/lpcxpresso-boards/lpcxpresso55s28-development-board:LPC55S28-EVK)
|
||||||
|
development board. They use the onboard WM8904 codec, so don't require any
|
||||||
|
additional hardware for audio I/O.
|
||||||
|
|
||||||
|
They can be programmed and debugged using the CMSIS-DAP that's on the board,
|
||||||
|
though due to the security features you may need to reset into the DFU
|
||||||
|
bootloader first.
|
||||||
|
|
||||||
|
```
|
||||||
|
cargo embed --release
|
||||||
|
```
|
||||||
|
|
||||||
|
Enable logging with `DEFMT_LOG` when building, but beware that enabling defmt
|
||||||
|
logs can cause timing failures, and _must_ be drained by the host, as it is
|
||||||
|
blocking.
|
||||||
|
|
||||||
|
They work on either USBFS or USBHS, but not both at the same time. The default
|
||||||
|
is USBHS. If you would like to run the example on USBFS, disable default
|
||||||
|
features and select USBFS:
|
||||||
|
|
||||||
|
```
|
||||||
|
cargo embed --release --no-default-features --features usbfs
|
||||||
|
```
|
||||||
|
|
||||||
|
### Interrupt-driven (`lpc55s28-evk`)
|
||||||
|
|
||||||
|
Running at 32bit/48khz. Simultaneous input and output. Works on USBFS and USBHS.
|
||||||
|
|
||||||
|
This is a minimal implementation intended to demonstrate the fundamental
|
||||||
|
structure of the class driver. The architecture is not recommended for a production
|
||||||
|
device, but it does work reliably on the happy path.
|
||||||
|
|
||||||
|
This is intended primarily as a reference implementation to aid understanding of
|
||||||
|
the class driver.
|
||||||
|
|
||||||
|
### DMA-based (`lpc55s28-evk-dma`)
|
||||||
|
|
||||||
|
Running at 32bit/96khz. Output only. Works on USBFS and USBHS.
|
||||||
|
|
||||||
|
A more realistic and robust implementation using DMA. It fills a static ring
|
||||||
|
buffer as data comes in from USB, while the DMA chases it around the ring,
|
||||||
|
draining into the TX FIFO. This is efficient and decouples interrupt latency
|
||||||
|
from data delivery. It uses the DMA interrupt to track consumed slots, but as
|
||||||
|
long as the USB doesn't catch up to the read slot before this happens, there is
|
||||||
|
a lot of slack for other things to be happening.
|
||||||
|
|
||||||
|
This is a more useful demonstration, but is still lacking correct handling of
|
||||||
|
edge cases, error conditions and so on you would want in a fully fleshed out
|
||||||
|
implementation. Particularly, it behaves poorly in underrun, since the DMA will
|
||||||
|
keep emitting from the ring regardless of whether the data is valid, which
|
||||||
|
sounds terrible.

//! DMA based audio output example for the LPCXpresso55S28 demo board

//!

//! Uses the onboard WM8904 DAC at 96KHz. Clock is generated by PLL0. Simple proportional feedback is implemented.
|
||||||
|
//!
|
||||||
|
//! USB walks around a static ring of slots, filling them as data comes in from
|
||||||
|
//! the host. DMA chases it, filling the I2S FIFO as it drains to the DAC.
|
||||||
|
//! Feedback ensures that the host doesn't overrun or underrun the ring.
|
||||||
|
//!
|
||||||
|
//! This implementation is more suitable for real use than the interrupt-based
|
||||||
|
//! example, but it is still missing many niceties and behaves worse in
|
||||||
|
//! anomalous situations since the DMA just keeps trucking over the ring
|

|
//! regardless of the data validity.
