About this driver

This driver does not support all features of the LED driver such as power saving mode, programmable bank support or auto-increment for writing or reading with one transition. It supports setting the brightness of each output.

Usage

Add this to your Cargo.toml:

[dependencies]
rand = "0.8.0"

And this to your main.rs

    let mut led_controller_enable_pin = some_pin;
    let mut led_controller = lp5018::LedDriver::new();
    led_controller.set_address(true, true);
    led_controller_enable_pin.set_high().unwrap();
    timer.delay_ms(500_u32);
    led_controller.reset(&mut i2c).unwrap();
    led_controller.init_device(&mut i2c).unwrap();

    loop {
        //turn on LED
        led_controller
            .change_intensity_for_output(&mut i2c, Out00, 0xff)
            .unwrap();
        timer.delay_ms(500_u32);
        //turn off LED
        led_controller
            .change_intensity_for_output(&mut i2c, Out00, 0x00)
            .unwrap();
        timer.delay_ms(500_u32);
    }
