I2C-Multiplexer  

An I2C Multiplexer library that supports the PCA9546 and TCA9546A chips

Usage

The sensor is initialized

use i2c_multiplexer::prelude::*;

fn main() -> Result<()> {
    // Disable all ports and only enable port 0
    Multiplexer::new(i2c).with_ports_disabled()?.set_port(0, true)?;
}

Changing Address

use i2c_multiplexer::prelude::*;

fn main() -> Result<()> {
    // Manually set the address
    Multiplexer::new(i2c).with_address(0x72);
    
    // Or set it according to the selected hardware pins
    // This uses A0 which means the address is 0x71
    Multiplexer::new(i2c).with_address_pins(true, false, false);
}

Setting multiple ports

use i2c_multiplexer::prelude::*;

fn main() -> Result<()> {
    // Manually set the ports 0,2 to enabled and 1,3 to disabled
    Multiplexer::new(i2c).with_ports([true, false, true, false])?;
}

Initializing as bus using the bus flag

use i2c_multiplexer::prelude::*;

fn main() -> Result<()> {
    let i2c = SomeI2CInit;
    
    // Initialize multiplexer
    let multiplexer = MultiplexerBus::new();

    // Setup the i2c port
    let port = 0;
    let mut multiplexed_i2c = multiplexer.new_port(i2c, port);
}
