Struct Voice 

#[repr(C, packed(1))]
pub struct Voice {
    pub frequency: WO<u16>,
    pub pulse_width: WO<u16>,

}

Registers for a single SID voice/channel

Fields

frequency: WO<u16>

FRELO/FRELO Frequency control (0x00-0x01)

pulse_width: WO<u16>

PWLO/PWHI Pulse waveform width (0x02-0x03)

control: WO<VoiceControlFlags>

VCREG Control register (0x04)

attack_decay: WO<u8>

ATDCY Attack/decay cycle duration (0x05)

sustain_release: WO<u8>

SUREL Sustain/Release Control (0x06)

Implementations

impl Voice

pub fn set_attack_decay(&self, attack_time: AttackTime, decay_time: DecayTime)

Sets the attack/decay cycle duration (ATDCY)

See e.g. Mapping the C64, page 162.

Example:

(*c64::SID).channel1.set_attack_decay(AttackTime::Ms38, DecayTime::Ms240);
