LED Lattice

begin()

Function:

Initialize the LED matrix

Syntax:

void begin()

Pay attention:
1.If you do not want to initialize LED with M5.begin (), call this Function before using LED

Example:

#include <M5Atom.h>

void setup() {
  M5.Lcd.begin();  //Initialize Atom LED latticeM5.Lcd.begin (); / / Initialize Atom LED lattice. 
}

void loop() {
}

setBrightness()

Function:

Set the brightness of the illuminated LED.

Syntax:

void setBrightness(uint8_t brightness)

Example:

#include "M5Atom.h"
void setup(){
  M5.begin(true, false, true); //Initialize M5Atom. 
}

void loop(){
  M5.dis.fillpix(0xffffff); //Illuminate the entire LED lattice with RBG color 0xffffff. 
  M5.dis.setBrightness(10); //Set the brightness of the illuminated LED
  delay(1000);

  M5.dis.fillpix(0xFFFF00);
  M5.dis.setBrightness(100);
  delay(1000);
}

setWidthHeight()

Function:

Set the width and height of the pattern

Syntax:

void setBrightness(uint8_t brightness)

run()

Function:

Start playing LED display

Syntax:

void run()

Pay attention:
1.If you do not want to initialize LED with M5.begin () and you want to use animation (), call this Function before using animation ()

Example:

#include <M5Atom.h>

void setup() {
  M5.Lcd.begin();  //Initialize Atom LED lattice.
  M5.Lcd.run();
}

void loop() {
}

animation()

Function:

Move a pattern in a specified direction at a specified speed

Syntax:

void animation(uint8_t *buffptr, uint8_t amspeed, uint8_t ammode, int64_t amcount)

Move direction:

Example:

#include "M5Atom.h"
extern const unsigned char AtomImageData[375 + 2];  //External reference stores the array of images shown (click image.c below to download and save to the same directory as .ino). 

void setup(){
    M5.begin(true, false, true);   //Clear the serial buffer and set the serial baud rate to 115200; initialize the LED matrix. 
    delay(50);
}

void loop(){
    //Move a pattern AtomImageData 25 steps in the specified direction kMoveLeft at a specified speed of 200
    M5.dis.animation((uint8_t *)AtomImageData, 200, LED_DisPlay::kMoveLeft, 25);
    delay(5250);
}

Pay attention:
1. image.c Picture download

animationrunning()

Function:

Get whether the pattern is in motion

Syntax:

boolean animationrunning()

Function return value

displaybuff()

Function:

Move the displayed content in a certain direction.

Syntax:

void displaybuff(uint8_t *buffptr, int8_t offsetx = 0, int8_t offsety = 0)

Pay attention:
1.x > 0 move to the right, y > 0 move down

Example:

#include "M5Atom.h"

extern const unsigned char AtomImageData[375 + 2];  //Click on the top image.c to download the array
void setup(){
  M5.begin(true, false, true);
  delay(50);
}

void loop(){
  M5.dis.displaybuff((uint8_t *)AtomImageData,-2, 0);    //Move the pattern 2 squares to the left
  delay(100);
}

drawpix()

Function:

Lights a LED (Number: 0mm 24) (Atom-Lite has only one light) in a specified RGB color.

Light the lamp LED at the coordinates of (xpene y) with the specified RGB color

Syntax:

void drawpix(uint8_t xpos, uint8_t ypos, CRGB Color)

void drawpix(uint8_t Number, CRGB Color)

Example:

#include "M5Atom.h"
void setup(){
    M5.begin(true, false, true);    //Initialize M5Atom. 
    delay(50);   //Delayed 50ms. 
    M5.dis.drawpix(0, 0xBBFFFF);  //Light the 0th LED with RBG color 0xBBFFFF. 
    //M5.dis.drawpix(0,0, 0xBBFFFF);  //Illuminate the LED at (0meme0) with RBG color 0xBBFFFF
}

void loop(){
}

Pay attention:
1. Download RGB conversion tool

fillpix()

Function:

Fill a RBG color into the entire LED lattice.

Syntax:

void fillpix(CRGB Color)

Example:

#include "M5Atom.h"
void setup(){
  M5.begin(true, false, true); //Initialize M5Atom. 
}

void loop(){
  M5.dis.fillpix(0xffffff);  //Illuminate the entire LED lattice with RBG color 0xffffff
}

clear()

Function:

Extinguish all lit LED

Syntax:

void clear()

Example:

#include "M5Atom.h"
void setup(){
    M5.begin(true, false, true);    //Initialize M5Stack. 
    delay(50);   //Delayed 50ms. 
    M5.dis.drawpix(0, 0xBBFFFF);
  //M5.dis.drawpix(0,0, 0xBBFFFF);
}

void loop(){
  M5.update();  //Read button press state. 
  if (M5.Btn.wasPressed()){
    M5.dis.clear();  //Extinguish all lit LED. 
  }
}
