ST7567S Display Controller Driver
This crate provides a driver for the ST7567S display controller that can be used with Rust embedded projects.
Features
- Supports I2C and SPI communication protocols via the
display_interface
crate. - Provides two display modes:
- Direct Write Mode (by default): This mode allows you to write directly to the display memory by calling the
draw
method. - Buffered Mode: This mode allows you to modify an internal buffer by using methods like
set_pixel
,clear
, or by using theembedded-graphics
crate. Once you have made your changes, you can call theflush
method to write the buffer to the display.
- Direct Write Mode (by default): This mode allows you to write directly to the display memory by calling the
Notes
- This driver is designed to work with a more common 128x64 resolution, instead of the original 132x65 resolution of the ST7567S controller.
- SPI communication is not tested yet.
Examples
Direct write mode
use st7567s::{
display::{DirectWriteMode, ST7567S},
interface::{I2CDisplayInterface, I2CInterface},
};
struct I2CStub;
impl embedded_hal::blocking::i2c::Write for I2CStub {
type Error = ();
fn write(&mut self, _addr: u8, _buf: &[u8]) -> Result<(), ()> {
Ok(())
}
}
let i2c = I2CStub;
let interface = I2CDisplayInterface::new(i2c);
let mut display = ST7567S::new(interface);
display.init().unwrap();
// Set all pixels to enabled state
display
.draw([0xff; 128 * 64 / 8].as_slice())
.unwrap();
Buffered mode + embedded_graphics
use st7567s::{
display::{BufferedMode, ST7567S},
interface::{I2CDisplayInterface, I2CInterface},
};
use embedded_graphics::{
mono_font::{ascii::FONT_6X10, MonoTextStyleBuilder},
pixelcolor::BinaryColor,
prelude::*,
text::{Baseline, Text},
};
struct I2CStub;
impl embedded_hal::blocking::i2c::Write for I2CStub {
type Error = ();
fn write(&mut self, _addr: u8, _buf: &[u8]) -> Result<(), ()> {
Ok(())
}
}
let i2c = I2CStub;
let interface = I2CDisplayInterface::new(i2c);
let mut display = ST7567S::new(interface)
.into_buffered_graphics_mode();
display.init().unwrap();
let text_style = MonoTextStyleBuilder::new()
.font(&FONT_6X10)
.text_color(BinaryColor::On)
.build();
Text::with_baseline("Hello world!", Point::zero(), text_style, Baseline::Top)
.draw(&mut display)
.unwrap();
Text::with_baseline("Hello Rust!", Point::new(0, 16), text_style, Baseline::Top)
.draw(&mut display)
.unwrap();
display.flush().unwrap();
