Implementations

impl DAC

pub fn get_state(&mut self) -> u8

(VGA) DAC state register (0x03C7)

pub fn set_pel_mask(&mut self, val: u8)

(VGA, MCGA) PEL mask register (0x03C6)

pub fn set_pel_read_index(&mut self, val: u8)

(VGA,MCGA,CEG-VGA) PEL address register (read mode) (0x03C7) Sets DAC in read mode and assign start of color register index (0..255) for following read accesses to 3C9h. Don’t write to 3C9h while in read mode. Next access to 03C8h will stop pending mode immediatly.

pub fn get_pel_write_index(&mut self) -> u8

(VGA,MCGA) PEL address register (0x03C8)

pub fn set_pel_write_index(&mut self, val: u8)

(VGA,MCGA) PEL address register (write mode) (0x03C8) Sets DAC in write mode and assign start of color register index (0..255) for following write accesses to 3C9h. Next access to 03C8h will stop pending mode immediately.

pub fn get_pel_data(&mut self) -> u8

(VGA,MCGA) PEL data register (0x03C9) Three consequtive reads (in read mode) in the order: red, green, blue. The internal DAC index is incremented each 3rd access.

pub fn set_pel_data(&mut self, val: u8)

(VGA,MCGA) PEL data register (0x03C9) Three consecutive writes (in write mode) in the order: red, green, blue. The internal DAC index is incremented on every 3rd access.

Trait Implementations

impl Clone for DAC

fn clone(&self) -> DAC

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Default for DAC

fn default() -> Self

Returns the “default value” for a type.
