WriteModulationBuffer

WriteModulationBuffer は, 指定したバンク・オフセットへ AM 波形 (&[u8]) を書き込む低レベルコマンド.

API

Rust

WriteModulationBuffer { bank, offset, data };

Python

WriteModulationBuffer(bank=bank, offset=offset, data=data)

C#

new WriteModulationBuffer(bank: bank, offset: offset, data: data);

フィールド	型	説明
bank	ModulationBank	書き込み先バンク
offset	usize	バンク内の書き込み開始オフセット
data	&[u8]	AM 波形サンプル列

WriteModulationBuffer は 1 フレームに収まる分しか書けない. 上限は WriteModulationBuffer::MAX_LEN で, 超えると送信時にエラーになる.

Example

WriteModulationBuffer → ConfigModulation → ActivateModulationBank で AM 波形を再生する例 (高レベルの Modulation と等価).

Rust

use autd3_rs::commands::{
    ActivateModulationBank, Clear, ConfigModulation, Synchronize, WriteModulationBuffer,
};
use autd3_rs::geometry::{Autd3, Geometry};
use autd3_rs::units::Hz;
use autd3_rs::value::{LoopBehavior, ModulationBank, SamplingConfig, TransitionMode};
use autd3_rs::Client;
use autd3_rs::udp::TransportOption;
use autd3_rs_modulation::{SineOption, modulation_buffer, sine};

let geometry = Geometry::new(vec![Autd3::default()]);
let option = TransportOption::default();
let mut client = Client::open(&geometry, &option).await?;
client.send(Clear).await?;
client.send(Synchronize).await?;

let mut data = modulation_buffer();
sine(150 * Hz, &SineOption::default(), SamplingConfig::FREQ_4K, &mut data)?;

let bank = ModulationBank::B0;

client.send(WriteModulationBuffer {
    bank,
    offset: 0,
    data: &data,
}).await?;
client.send(ConfigModulation {
    bank,
    config: SamplingConfig::FREQ_4K,
    size: data.len(),
    loop_behavior: LoopBehavior::Infinite,
}).await?;
client.send(ActivateModulationBank {
    bank,
    transition_mode: TransitionMode::Immediate,
}).await?;
