WritePatternBuffer

WritePatternBuffer is a low-level command that writes a Pattern (the Emission of each transducer) to the specified bank and index.

API

Rust

WritePatternBuffer {
    bank,
    index,
    emissions,
};

Python

WritePatternBuffer(
    bank=bank,
    index=index,
    emissions=emissions,
)

C#

new WritePatternBuffer(
    bank: bank,
    index: index,
    emissions: emissions
);

Field	Type	Description
bank	PatternBank	Destination bank
index	u16	Destination index for writing within the bank
emissions	&[Vec<Emission>]	Per-device emission pattern

Example

Multiple low-level commands are sent together in a single datagram. The following is an example of playing a single Pattern via WritePatternBuffer → ConfigPattern → ChangePatternBank (equivalent to the high-level Pattern).

Rust

use core::num::NonZeroU16;

use autd3_rs::commands::{ChangePatternBank, ConfigPattern, WritePatternBuffer};
use autd3_rs::geometry::{Autd3, Geometry, offset};
use autd3_rs::units::{m, mm, s};
use autd3_rs::value::{LoopBehavior, PatternBank, SamplingConfig, TransitionMode};
use autd3_rs::{Client, ClientConfig};
use autd3_rs_link_nop::Nop;
use autd3_rs_pattern::{FocusOption, focus, wavelength};

let geometry = Geometry::new(vec![Autd3::default()]);
let client = Client::open(&geometry, Nop, ClientConfig::default()).await?;

let mut emissions = geometry.pattern_buffer();
focus(
    &geometry,
    geometry.center() + offset(0.0 * mm, 0.0 * mm, 150.0 * mm),
    wavelength(340.0 * m / s),
    &FocusOption::default(),
    &mut emissions,
);

let bank = PatternBank::B0;

let mut builder = client.datagram_builder();
builder.push(WritePatternBuffer {
    bank,
    index: 0,
    emissions: &emissions,
});
builder.push(ConfigPattern {
    bank,
    config: SamplingConfig::new(NonZeroU16::MAX),
    size: 1,
    loop_behavior: LoopBehavior::Infinite,
});
builder.push(ChangePatternBank {
    bank,
    transition_mode: TransitionMode::Immediate,
});
let frames = builder.build()?;
for frame in &frames {
    client.send_checked(frame).await?;
}

client.close().await?;
