Enum DecodeMode

#[repr(u8)]
pub enum DecodeMode {
    NoDecode = 0,
    Digit0 = 1,
    Digits0To3 = 15,
    AllDigits = 255,
}

Decode mode configuration for the MAX7219 display driver.

Code B decoding allows the driver to automatically convert certain values (such as 0-9, E, H, L, and others) into their corresponding 7-segment patterns. Digits not using Code B must be controlled manually using raw segment data.

Use this to configure which digits should use Code B decoding and which should remain in raw segment mode.

Variants

NoDecode = 0

Disable Code B decoding for all digits (DIG0 to DIG7).

In this mode, you must manually set each segment (A to G and DP) using raw segment data.

Digit0 = 1

Enable Code B decoding for only digit 0 (DIG0).

All other digits (DIG1 to DIG7) must be controlled manually.

Digits0To3 = 15

Enable Code B decoding for digits 0 through 3 (DIG0 to DIG3).

This is commonly used for 4-digit numeric displays.

AllDigits = 255

Enable Code B decoding for all digits (DIG0 to DIG7).

This is typically used for full 8-digit numeric displays.

Implementations

impl DecodeMode

pub const fn value(self) -> u8

Convert decode mode to u8 value

Trait Implementations

impl Clone for DecodeMode

fn clone(&self) -> DecodeMode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DecodeMode

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

Formats the value using the given formatter.

impl PartialEq for DecodeMode

fn eq(&self, other: &DecodeMode) -> 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.
