Function width_encode

custom_components/flipper_rc/pulse.py:163–202

Encode a list of bytes into pulses and gaps based on given timings. Args: values (list of int): List of byte values to encode. leading_pulse (int): Duration of the leading pulse. leading_gap (int): Duration of the gap following the leading pulse. gap (int):

(values, leading_pulse, leading_gap, gap, pulse_0, pulse_1, bit_length=None, msb_first=False)

    return pulses

    Encode a list of bytes into pulses and gaps based on given timings.

    Args:
        values (list of int): List of byte values to encode.
        leading_pulse (int): Duration of the leading pulse.
        leading_gap (int): Duration of the gap following the leading pulse.
        gap (int): Duration of the gap between pulses.
        pulse_0 (int): Duration of the pulse representing a '0' bit.
        pulse_1 (int): Duration of the pulse representing a '1' bit.
        bit_length (int, optional): Total number of bits to encode. If None, encode all bits in `values`. Defaults to None.
        msb_first (bool, optional): If True, encode the most significant bit first. If False, encode the least significant bit first. Defaults to False.

    Returns:
        list of int: List of pulse and gap durations representing the encoded values.

    Raises:
        ValueError: If `bit_length` is greater than the number of bits in `values`.
