Implementations§

Source §

impl Display

Source

pub fn write_command(&mut self, byte: &[u8]) -> Result<()>

Write a command byte to the device. The byte should be of the type &[u8]. The DC pin is set low to indicate that the byte being written is a command byte.

Source

pub fn write_data(&mut self, byte: &[u8]) -> Result<()>

Write a data byte to the device. The byte should be of the type &[u8]. The DC pin is set high to indicate that the byte being written is a data byte

Source

pub fn spi_write_byte(&mut self, byte: &[u8]) -> Result<()>

Raw SPI write byte function. DO NOT USE. use write_command or write_data instead.

Source

pub fn i2c_write_byte(&self, _byte: &[u8]) -> Result<()>

TODO: Add Support for I2C

Source

pub fn reset(&mut self) -> Result<()>

Reset the display.

Source

pub fn render(&mut self) -> Result<()>

The Graphics buffer is stored in the Display { memory: Vec<u8> } field. The ws_oled_driver::gfx library functions work on the memory field. It writes the pixes onto the memory field. The render function dumps the memory field onto the display.
