MOS Technology Sound Interface Device (SID)

Fields§

§channel1: Voice§channel2: Voice§channel3: Voice§filter_cutoff: WO<u16>§resonance_and_filter_setup: WO<u8>

RESON Filter resonance control (0x17)

§volume_filter_mode: WO<u8>

SIGVOL Volume and filter select (0x18)

Implementations§

Source §

impl MOSSoundInterfaceDevice

Source

pub fn start_random_generator(&self)

Start noise generation on SID channel 3.

Example:

c64::sid().start_random_generator();
let random_byte = c64::sid().rand8(20);

More information here.

Source

pub fn rand8(&self, max_value: u8) -> u8

Random byte in the interval (0, max_value)

Source

pub fn random_byte(&self) -> u8

Random byte in the interval (0, 255)

§Examples

c64::sid().start_random_generator();
let value = c64::sid().random_byte();

More information here. Currently there’s no way to select the subsong as this requires that the accumulator is set. Possibly this can be done wrapping function pointers to raw assembler code.
