Struct display_interface_parallel_gpio::PGPIO8BitInterface

pub struct PGPIO8BitInterface<BUS, DC, WR> { /* fields omitted */ }

Parallel 8 Bit communication interface

This interface implements an 8-Bit “8080” style write-only display interface using any 8-bit OutputBus implementation as well as one OutputPin for the data/command selection and one OutputPin for the write-enable flag.

All pins are supposed to be high-active, high for the D/C pin meaning “data” and the write-enable being pulled low before the setting of the bits and supposed to be sampled at a low to high edge.

Implementations

impl<BUS, DC, WR> PGPIO8BitInterface<BUS, DC, WR> where
    BUS: OutputBus<Word = u8>,
    DC: OutputPin,
    WR: OutputPin, 

pub fn new(bus: BUS, dc: DC, wr: WR) -> Self

Create new parallel GPIO interface for communication with a display driver

pub fn release(self) -> (BUS, DC, WR)

Consume the display interface and return the bus and GPIO pins used by it
