Introduction

• This library code implements the driving code of Aurora(V231) or Wide-temperature EPDs with iTC driver and embedded OTP LUT made by Pervasive Displays Inc (PDi). This is compatible with EPD Extension Kit Gen 3 (EXT3).
• It implements the global (GU) and fast update modes (FU).
• The library supports the following EPD sizes: 1.52", 1.54", 2.06", 2.13", 2.66", 2.71", 2.71"(A), 2.92", 3.70", 4.20", 4.37"
• This library was tested with Launchpad (Tiva-C) with TM4C123, MSP432P401R, Arduino M0 Pro, and Raspberry Pi Pico.

Installation

Download the ZIP file of this library and install as instructed in Arduino or Energia.

Hardware Setup

• If using Launchpad (Tiva-C) with TM4C123 or MSP432P401R, the SPI pins are by default:

// Using EXT3
    SCK = 7     // BROWN
    BUSY = 11   // RED
    D/C = 12    // ORANGE
    RST = 13    // YELLOW
    MOSI = 15   // BLUE
    ECSM = 19   // GRAY
    

• If using Arduino M0 Pro,

  SCK = 13 
  BUSY = 4  
  D/C = 5
  RST = 6
  MOSI = 12
  ECSM = 8

• If using Raspberry Pi Pico,

  SCK = 18 
  BUSY = 13  
  D/C = 12
  RST = 11
  MOSI = 19
  ECSM = 17

For further wiring guidance, check out our Wiki: EXT3.

EPD_Driver Demo

• The sample code implements both global and fast update functionality for a 1.52" Wide Temperature+Fast Update EPD (E2152KS0J1).

First, a BW(black and white) image is flashed.
Then, after a two-second delay, a sequence of BW fast images are flashed.

• The demo currently includes sample images for all the supported EPD sizes mentioned above. To implement the demo on these other sizes, update the following lines

//------------------------------------------------------------
// DEMO Image Set <Comment out when in User Mode>
// Screen Size: 152, 154, 206, 213, 266, 271, 292, 370, 417, 437
#define SCREEN 152
#include "globalupdate_src/demoImageData.h"
#include "fastupdate_src/demoImageData.h"

• Then select the appropriate EPD size, development board and extension kit:

#define EPD_SIZE eScreen_EPD_152
#define BOARD_TYPE boardRaspberryPiPico_RP2040_EXT3
