Introduction

• This library code implements the driving code of Aurora(V231) or Spectra EPDs with iTC driver made by Pervasive Displays Inc (PDi). This is compatible with either EPD Extension Kit Gen 2 (EXT2) and EPD Extension Kit Gen 3 (EXT3).
• It implements the global update mode (GU). However, the same code for fast and partial update are shared upon request. Contact PDi for further details.
• The library supports the following EPD sizes: 5.81", 7.41"
• This library was tested with Launchpad (Tiva-C) with TM4C123, MSP432P401R, Arduino M0 Pro, and Raspberry Pi Pico.
• Driving code for Large-sized EPD (9" and greater) will soon be included in a later release.

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
  PNLON = 11	only for EXT2
  BS = 9	only for EXT2

• If using Raspberry Pi Pico,

  SCK = 18 
  BUSY = 13  
  D/C = 12
  RST = 11
  MOSI = 19
  ECSM = 17
  PNLON = 8	only for EXT2
  BS = 7	only for EXT2

For further wiring guidance, check out the User Manuals of EXT2 and EXT3.

EPD_Driver Demo

• The sample code implements a global update functionality for a 5.81" Aurora Mb (V231) EPD (E2581CS0B1).

First, a BW(black and white) image is flashed.

After a second, a BWR (black, white, red) image follows.

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

//------------------------------------------------------------
// DEMO Image Set <Comment out when in User Mode>
// Screen Size: 581, 741
#define SCREEN 581
#include "globalupdate_src/demoImageData.h"
// User Mode Image Set
//#include "globalupdate_src/userImageData.h"

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

  // EPD_Driver epdtest(eScreen_EPD_581, boardLaunchPad_EXT3);
  // EPD_Driver epdtest(eScreen_EPD_581, boardArduinoM0Pro_EXT2);
  EPD_Driver epdtest(eScreen_EPD_581, boardRaspberryPiPico_RP2040_EXT3);
  // EPD_Driver epdtest(eScreen_EPD_581, boardRaspberryPiPico_RP2040_EXT2);
