Introduction

• This library code implements the driving code of Aurora(V231) EPD 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: 5.81"
• 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
    
 // Using EXT2
    SCK = 7    
    BUSY = 8  
    D/C = 9
    RST = 10
    MOSI = 15
    ECSM = 19
    PNLON = 11
    BS = 17

• 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 the User Manual EXT3.

EPD_Driver Demo

• The sample code implements both global and fast update functionality for a 5.81" Monochrome+Fast EPD (E2581PS0B1).

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: 581
#define SCREEN 581
#include "globalupdate_src/demoImageData.h"
#include "fastupdate_src/FuPu_Data_581.h"

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

#define EPD_SIZE eScreen_EPD_581
#define BOARD_TYPE boardRaspberryPiPico_RP2040_EXT3
