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);

}
