Operation Description

Sample Code

Initialize IL3895 e-paper and display 4 different black strings.

#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); //Select the corresponding pins
    epaper.begin(EPAPER_CS, Font_CS, EPAPER_DC, EPAPER_BUSY);

    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);

    /*Displays a string, black font*/
    epaper.disString(41,12,1,"DFRobot Black&White Ink Screen",BLACK);
    epaper.flush(PART);

    /*Displays a string, black font*/
    epaper.disString(57,40,1,"《+-*/=!@#$%&*(》",BLACK);
    epaper.flush(PART);

    /*Display large font*/
    epaper.disString(61,65,2,"Large Font",BLACK);
    epaper.flush(PART);
}

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

Result

The display includes Chinese characters, ASCII code characters, punctuation.
