Struct Pixels 

pub struct Pixels<I2C> { /* private fields */ }

Driver for the Modulino Pixels module.

Example

use modulino::{Pixels, Color};

let mut pixels = Pixels::new(i2c)?;

// Set individual LED
pixels.set_color(0, Color::RED, 50)?;

// Set all LEDs to the same color
pixels.set_all_color(Color::BLUE, 25)?;

// Apply changes
pixels.show()?;

// Clear all LEDs
pixels.clear_all()?;
pixels.show()?;

Implementations

impl<I2C, E> Pixels<I2C>

where I2C: I2c<Error = E>,

pub fn new(i2c: I2C) -> Result<Self, E>

Create a new Pixels instance with the default address.

pub fn new_with_address(i2c: I2C, address: u8) -> Result<Self, E>

Create a new Pixels instance with a custom address.

pub fn address(&self) -> u8

Get the I2C address.

pub fn set_color( &mut self, index: usize, color: Color, brightness: u8, ) -> Result<&mut Self, E>

Set the color of a specific LED.

Arguments

• index - LED index (0-7)
• color - The color to set
• brightness - Brightness level (0-100)

pub fn set_rgb( &mut self, index: usize, r: u8, g: u8, b: u8, brightness: u8, ) -> Result<&mut Self, E>

Set the color of a specific LED using RGB values.

Arguments

• index - LED index (0-7)
• r - Red component (0-255)
• g - Green component (0-255)
• b - Blue component (0-255)
• brightness - Brightness level (0-100)

pub fn set_brightness( &mut self, index: usize, brightness: u8, ) -> Result<&mut Self, E>

Set the brightness of a specific LED without changing its color.

Arguments

• index - LED index (0-7)
• brightness - Brightness level (0-100)

pub fn set_all_color(&mut self, color: Color, brightness: u8) -> &mut Self

Set the color of all LEDs.

pub fn set_all_rgb(&mut self, r: u8, g: u8, b: u8, brightness: u8) -> &mut Self

Set all LEDs to the same RGB color.

pub fn set_range_color( &mut self, from: usize, to: usize, color: Color, brightness: u8, ) -> &mut Self

Set the color of a range of LEDs.

Arguments

• from - Starting index (inclusive)
• to - Ending index (inclusive)
• color - The color to set
• brightness - Brightness level (0-100)

pub fn set_all_brightness(&mut self, brightness: u8) -> &mut Self

Set the brightness of all LEDs without changing their colors.

pub fn clear(&mut self, index: usize) -> Result<&mut Self, E>

Clear (turn off) a specific LED.

pub fn clear_range(&mut self, from: usize, to: usize) -> &mut Self

Clear a range of LEDs.

pub fn clear_all(&mut self) -> &mut Self

Clear all LEDs.

pub fn show(&mut self) -> Result<(), E>

Apply the current LED states to the hardware.

This must be called after setting colors for changes to take effect.

pub fn set_color_show( &mut self, index: usize, color: Color, brightness: u8, ) -> Result<(), E>

Set a color and immediately show it.

pub fn release(self) -> I2C

Release the I2C bus.
