Crate muses72323 

muses72323

A Rust driver library for the MUSES72323 electronic volume controller IC.

This crate provides type-safe command structures for controlling the MUSES72323, a high-quality 2-channel electronic volume controller with the following features:

• Volume control: 0dB to -111.75dB (0.25dB steps)
• Gain control: 0dB to +21dB (+3dB steps)
• Soft step function to reduce zipper noise
• Zero-cross detection
• Independent or linked L/R channel control

Usage

use muses72323::commands::{SetVolume, SetGain, SoftClock, Channel, Gain, ClockDiv, ZeroWindowVolt};

// Set volume to -20dB (80 steps of 0.25dB)
let volume_cmd = SetVolume::new()
    .with_chip_addr(0b00)
    .with_channel(Channel::LorBoth)
    .with_is_soft_step(true)
    .with_volume(80);

// Set gain to +12dB for both channels
let gain_cmd = SetGain::new()
    .with_chip_addr(0b00)
    .with_l_gain(Gain::Gain12db)
    .with_r_gain(Gain::Gain12db)
    .with_l_r_cont(true)
    .with_zero_cross_off(false);

// Configure soft clock with internal clock and 1/32 division
let clock_cmd = SoftClock::new()
    .with_chip_addr(0b00)
    .with_internal_clock(true)
    .with_clock_div(ClockDiv::Div32)
    .with_zero_window_volt(ZeroWindowVolt::Mul4);

// Convert to u16 for transmission
let volume_data: u16 = volume_cmd.into();
let gain_data: u16 = gain_cmd.into();
let clock_data: u16 = clock_cmd.into();

Commands

The crate provides three main command structures:

• SetVolume: Control volume level with soft step option
• SetGain: Control gain and L/R channel linking
• SoftClock: Configure clock settings and zero-cross detection

All commands are converted to 16-bit values for transmission to the MUSES72323 IC.
