Operation Description

Sample Code

Initialize IL3895 e-paper screen, display string and draw various black shapes.

#include "Arduino.h"
#include "DFRobot_IL3895_SPI.h"

DFRobot_IL3895_SPI epaper;

#define EPAPER_CS  D3
#define Font_CS  D6
#define EPAPER_DC  D8
#define EPAPER_BUSY     D7

void setup(void)
{
    Serial.begin(115200);
    epaper.begin(EPAPER_CS, Font_CS, EPAPER_DC, EPAPER_BUSY); //Select the corresponding pins
    epaper.fillScreen(WHITE);//Clear the screen and display white
    epaper.flush(FULL);  //Refresh screen display
    /*Displays a string, black font*/
    epaper.disString(0,0,1,"SPI",BLACK);
    epaper.flush(PART);

    /*Let me draw a red dot*/
    for(uint8_t x=12,y=12; y<110; y+=3)
    {
        epaper.drawPixel(x,y,BLACK);
    }
    epaper.flush(PART);

    /*Draw two lines*/
    epaper.drawLine(24,12, 36,110,BLACK);
    epaper.drawLine(36,12, 24,110,BLACK);
    epaper.flush(PART);

    /*Draw a red rectangle*/
    epaper.drawRect(48,12, 40,98,BLACK);
    epaper.flush(PART);

    /*Fill a rectangle with black*/
    epaper.fillRect(55,19, 26,84,BLACK);
    epaper.flush(PART);

    /*Draw a hollow circle*/
    epaper.drawCircle(122,37, 25,BLACK);
    epaper.flush(PART);

    /*Draw a solid circle*/
    epaper.fillCircle(122,37, 18,BLACK);
    epaper.flush(PART);

    /*Draw a rounded rectangle*/
    epaper.drawRoundRect(97,67, 50,43, 10,BLACK);
    epaper.flush(PART);

    /*Fill in a rounded rectangle*/
    epaper.fillRoundRect(102,72, 40,33, 8,BLACK);
    epaper.flush(PART);

    /*Draw a triangle*/
    epaper.drawTriangle(180,12, 155,110, 205,110,BLACK);
    epaper.flush(PART);

    /*Fill in a triangle*/
    epaper.fillTriangle(180,23, 162,105, 198,105,BLACK);
    epaper.flush(PART);

    /*Prompt characters*/
    epaper.disString(215,12, 2,"pic",BLACK);
    epaper.disString(215,78, 2,"shape",BLACK);
    epaper.flush(PART);
}

void loop(void)
{
    delay(8000);
}

Result

The display includes drawing points, drawing lines, drawing rectangular boxes，drawing filled rectangles, drawing circles, drawing filled circles, drawing rounded rectangles, drawing filled rounded rectangles, and displaying characters (including letters and Chinese characters).
