Struct Config 

pub struct Config {
    pub i2c_addr: I2cAddr,
    pub mode: ControlRegisterMode,
}

Configuration of the DS3502 for set-up.

Differences from default behavior

According to the datasheet, by default, the control register (CR) is initialized in Mode 0 (0x00), so I2C writes to both the Wiper Register (WR) and initial value register (IVR), which saves the WR value to the EEPROM.

The EEPROM has a limited number of write cycles, so the default configuration initializes the driver with CR in Mode 1 (0x80) the factory behavior by setting the control register mode to be wiper register only.

To restore factory behavior set the mode to ControlRegisterMode::WiperAndInitialValue

Fields

i2c_addr: I2cAddr

The default I2C address is 0x28

mode: ControlRegisterMode

By default, EEPROM saves are disabled, see ControlRegisterMode for more details.

Trait Implementations

impl Clone for Config

fn clone(&self) -> Config

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Config

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for Config

fn default() -> Self

Returns the “default value” for a type.

impl Hash for Config

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Config

fn eq(&self, other: &Config) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Copy for Config

impl Eq for Config

impl StructuralPartialEq for Config
