Rust Drivers for the ACS37800 Energy Metering IC

[!IMPORTANT] This driver is a work in progress. Only the I²C variants of the IC are currently supported. Reading the EEPROM registers is the only currently supported operation.

Example

The following is an example of using the driver. Async support for embedded-hal is provided when the async feature is enabled.

// Instantiate the I2C bus device
let i2c = I2cdev::new("/dev/i2c-1").unwrap();

// Instantiate the ACS37800 driver
let mut acs37800 = Acs37800::builder().i2c(i2c).build();

// Read the EEPROM data
match acs37800.read_eeprom() {
    Ok(eeprom) => {
        println!("{eeprom:#?}");
    }
    Err(cause) => {
        eprintln!("Reading EEPROM failed: {cause}");
    }
}

The code above will print out:
