Struct Timing 

pub struct Timing {
    pub time_0_low: u16,
    pub time_0_high: u16,
    pub time_1_low: u16,
    pub time_1_high: u16,
    pub reset_us: u16,
}

Defines the timing for a certain smart LED type.

All common smart LEDs are controlled by sending PWM-like pulses, in two different configurations for high and low. The required timings (and tolerances) can be found in the relevant datasheets.

Provided timings: SK68XX_TIMING, WS2812B_TIMING, WS2811_TIMING, WS2812_TIMING.

Fields

time_0_low: u16

Low time for zero pulse, in nanoseconds.

time_0_high: u16

High time for zero pulse, in nanoseconds.

time_1_low: u16

Low time for one pulse, in nanoseconds.

time_1_high: u16

High time for one pulse, in nanoseconds.

reset_us: u16

Time for the reset that is required in between transmissions, in microseconds. Depending on the rmt’s frequency, it can have a maximum of ~800us at 80mhz, ~2000us at 32mhz, etc.

The calculation is: max_reset_pulse_us = 0xfffe / rmt_freq_mhz. 0xfffe(= 0x7fff * 2) is the max amount of ticks in a single PulseCode.

Implementations

impl Timing

pub const fn with_reset_us(self, reset_us: u16) -> Self

Returns this timing configuration with the provided reset time. Different revisions of the same led might have different reset times, this is the reason behind this function.

Trait Implementations

impl Clone for Timing

fn clone(&self) -> Timing

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Timing
