SH1106 I2C OLED on linux embedded hal

[mhanusek]

Hello.
I trying run this code with OLED SH1106 Driver and linux embedded hal but not working.

I found similar example

use sh1106::{prelude::*, Builder};
use linux_embedded_hal::I2cdev;

use embedded_graphics::{
    mono_font::{ascii::FONT_6X10, MonoTextStyleBuilder},
    pixelcolor::BinaryColor,
    prelude::*,
    text::{Baseline, Text},
};

const SLAVE_ADDR: u16 = 0x3c;

fn main() 
{
    let mut i2c = I2cdev::new("/dev/i2c-1").unwrap();
    i2c.set_slave_address(SLAVE_ADDR).unwrap();

    let mut display: GraphicsMode<_> = Builder::new().connect_i2c(i2c).into();

    display.init().unwrap();
    display.flush().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();


    loop {}
}

but not working

What is not working?

[mhanusek]

Does not show text on the display.

Example in Python is working. I would like to do the same in Rust.

from luma.core.interface.serial import i2c
from luma.core.render import canvas
from luma.oled.device import sh1106

serial = i2c(port=1, address=0x3C)
device = sh1106(serial)

with canvas(device) as draw:
    draw.rectangle(device.bounding_box, outline="white", fill="black")
    draw.text((30, 40), "Hello World", fill="white")

while True:
    pass

It's working.

use sh1106::{prelude::*, Builder};
use linux_embedded_hal::I2cdev;

use embedded_graphics::{
    mono_font::{ascii::FONT_6X10, MonoTextStyleBuilder},
    pixelcolor::BinaryColor,
    prelude::*,
    text::{Baseline, Text},
};

const SLAVE_ADDR: u16 = 0x3c;

fn main() 
{
    let mut i2c = I2cdev::new("/dev/i2c-1").unwrap();
    i2c.set_slave_address(SLAVE_ADDR).unwrap();

    let mut display: GraphicsMode<_> = Builder::new().connect_i2c(i2c).into();

    display.init().unwrap();
    display.flush().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();

    loop {}
}
