Struct MaxMatrix

pub struct MaxMatrix<DataPin, LoadPin, ClockPin> { /* private fields */ }

The Struct to communicate with the MAX7219 LED Matrix

Implementations

impl<DataPin: OutputPin, LoadPin: OutputPin, ClockPin: OutputPin> MaxMatrix<DataPin, LoadPin, ClockPin>

pub fn reload(&mut self)

Reload the data from the buffer to the LED Matrix

pub fn new(data: DataPin, load: LoadPin, clock: ClockPin, num: u8) -> Self

Creates a new instance of the MaxMatrix struct
data - The data pin
load - The load pin
clock - The clock pin
num - The amount of LED Matrices connected

pub fn init(&mut self)

Initializes the LED Matrix with default values

pub fn clear(&mut self)

Clears the Buffer and the LED Matrix

pub fn set_intensity(&mut self, intensity: u8)

Sets the brightness of the LED Matrix

pub fn set_column(&mut self, col: u8, value: u8)

Sets an entire column of the LED Matrix
The value is a byte where each bit represents a pixel

pub fn set_column_all(&mut self, col: u8, value: u8)

Sets a colum of all connected LED Matrices

pub fn update_buffer_at(&mut self, col: u8, row: u8, value: bool)

Updates the buffer at a specified position
This does not automatically refresh the displays

pub fn set_dot(&mut self, col: u8, row: u8, value: bool)

Sets a pixel at a specified position and refreshes the displays

pub fn shift_left(&mut self, rotate: bool, fill_zero: bool)

Shifts the entire buffer to the left
rotate - If true, the last column will be moved to the first position
fill_zero - If true, the last column will be set to 0

pub fn shift_right(&mut self, rotate: bool, fill_zero: bool)

Shifts the entire buffer to the right
rotate - If true, the last column will be moved to the first position
fill_zero - If true, the last column will be set to 0

pub fn shift_up(&mut self, rotate: bool)

Shifts the entire buffer up
rotate - If true, the last row will be moved to the first position

pub fn shift_down(&mut self, rotate: bool)

Shifts the entire buffer down
rotate - If true, the last row will be moved to the first position
