1. Introduction
1.1 Overview
Thank you for purchasing the EPD Extension Kit/Board Generation 2 (EXT Gen2, EXT2) for
low-power electrophoretic paper display (EPD) solutions. This document provides an
overview of the kit and is organized into four main sections.
1. The EXT2 introduction and supported EPD, material and drivers
2. Getting started with the EXT2 to drive EPD
3. Hardware instruction of EXT2 kit
4. Working with Cypress PSoC Creator code
The 1st and 2nd sections are most of the user guide to instruct how to use the EXT2 kit and
get the EPD working. The 3rd and section are more details of developing EPDs with EXT2 kit
and provided project code.
The EXT2 is a new EPD Extension board supports driving all of Pervasive Displays Inc. (PDI)’s
EPD panels lineup. It has 20 flying leads can bridge with your project/product or other
development kit.
The project of EXT2 is open source code provides driving waveform and command interface
to update content on EPD panel for developer to start working with EPD application easily.

The EXT2 board supports driving most of the PDI’s EPD panels with the 40 and 24/34 pins
FPC connector. The EXT2 board has embedded EPD driving circuit which are soldered at the
backside.
eTC and iTC will be explained later.

1.3 EPD Displays
Figure 1-3 Structure layer of EPD
1.3.1 FPL (E ink Imaging film):
Made by E-ink which is embedded in PDI’s EPD panels. The EXT2 board supports driving the
following films:
-Aurora Ma: also call V230. The display color is black and white. It supports
operating at wide temperature from -20°C to +50°C. It has to load special driving
waveform to get the display works. This film type display is suggested for lower
temperature operation is the major criteria only.
-Aurora Mb: also call V231. The display color is black and white. Most of the cases,
The Aurora Mb film type display provides the best performance, faster update
speed and lower power consumption. It supports operating at room temperature
from 0°C to +50°C.
-Spectra: also call E4. The display color is red, black and white, three colors. It
supports operating at room temperature from +0°C to +40°C
-Spectra Yellow: The display color is yellow, black and white, three colors. It
supports operating at room temperature from +10°C to +40°C
-Aurora -25: also call V430. The display color is black and white. It supports
operating at a freezer temperature from -25°C to +10°C. This film type display is
suggested for lower temperature operation is the major criteria only.
1.3.2 COG (Chip on Glass):
also call Tcon (TC, Timing controller) or Driver IC which is mounted on TFT glass of EPD display.
-eTC: external Tcon, the driving waveform and flow are controlled by the host MCU
(microcontroller). Developer needs to manage most of the driving stages, frame
time and data flow by the MCU of host control board.
The eTC includes PDI’s G1, G1b and G2 COG (where G1/G1b are EOL (end of life)).
The pin number of FPC (flexible printed circuit) of eTC is 40 pins.

EPD EXT2 with Cypress PSoC 4 BLE module 7 [User’s Guide] Rev.01
-iTC: internal Tcon, the driving waveform and settings are managed by Lookup Table
(LUT). The LUT is serial hex array includes the waveform parameters. User will need
to send defined LUT and image data to COG. The COG will extract the waveform
settings from the LUT to update display by following image data.
The pin number of FPC of iTC is 24 or 34.

1.4 Cypress PSoC 4 Bluetooth® Low Energy (BLE) 4.1 Compliant Pioneer Kit
The Cypress PSoC 4 Bluetooth® Low Energy (BLE) 4.1 Compliant Pioneer Kit is excluded in
the EXT2 kit, so user and developer has to purchase the PSoC 4 BLE kit on Cypress official
website or other online webshop.
The BLE Pioneer Kit supports system-level designs by using PSoC Creator

2. Getting Started
This section provides instructions to set up the EXT2 kit with Cypress PSoC 4 BLE kit and use
the PSoC Creator to update image on EPD display.
There are two steps to prepare the kit:
(1) Assembling the EXT2 board with Cypress PSoC 4 BLE kit
(2) Programming firmware to PSoC 4 BLE kit
2.1 Assembling the EXT2 board with Cypress PSoC 4 BLE kit
We will need to set the jumpers of Cypress PSoC 4 BLE kit in order to get works at a proper
system voltage and programmable.
2.1.1 Adjust the Jumpers of Cypress PSoC 4 BLE kit
Cypress PSoC 4 BLE kit

When connecting with any EPD, please always check with this table and switch each shift
register from S1 to S8 accordingly. The 0 means Off and set the shift register at the bottom.
The 1 means On and set the shift register to the top. The dash means (don’t care) either 0 or
1 is fine.

2.1.4 How to bridge EXT2 with other development kit
If you will use our EXT2 board to bridge with your product or other development kit, there is
Bridging header (J5) which is pin-to-pin to J4 and J6. The pin assignment is listed on the front
side of PCB. Please use the 90 degree 20-pins header to solder on the backside of PCB like
the picture below.
We highly recommend cutting the protruding portion of the pin header in order to avoid
breaking the EPD.
After soldering the header on the EXT2 board, you are able to connect the bridging cable
with the pin headers of other development kit or your product.
Please note there is a white dot on the connector of bridging cable indicates the pin 1.

2.1.5 Bridge EXT2 board and Cypress PSoC 4 BLE kit
After adjusting the jumpers of Cypress PSoC 4 BLE kit and soldered the 90 degree 20-pins
header on J5 of EXT2 board, please use the bridging cable to connect the EXT2 board with
Cypress PSoC 4 BLE kit. This are two 20 pins header(J5) at the EXT2 board allows user to
connect any development board. Please make sure the assembly signal headers of EXT2
board is aligned with Cypress PSoC BLE kit ports.

3. Working with Cypress PSoC Creator Project Code
The Single driver will toggle between two images right away after programming the project.
It helps you to simply test the basic global update function with your connected EPD. It’s also
the driving waveform that you will migrate to your product using the chosen EPD.
The descriptions in this section will focus on the single driver.
3.1 EPD_drivers Project
All of the driving waveform source code of supported EPDs with different FPL and driver are
placed in this project
FPL_drivers folder:
You can find all the driving code under this folder for your chosen EPD. If you cannot find
the model in this folder, please contact us to request the driving source code.
The more advanced version of the project, the more driving code of EPDs will be
supported under this folder. You will find the file format is like the configuration that we
describe before:
DriverType_(DriverID if eTC)_Size_FPL
The captured picture below is for example. Your project code may be listed less or more
than the example.

EPD EXT2 with Cypress PSoC 4 BLE module 18 [User’s Guide] Rev.01
-EPD_drivers.h:
This file defines the main structures of EPD and COG type, the enumerations and
the constants.
-DriverType_Size_FPL.*:
The most of driving source code for each supported EPD including the power on,
initialization, update and power off stages. This is the waveform code you will
migrate into your project for driving your chosen EPD..
-iTC_Engine.*:
This file is used for iTC EPDs. In each of iTC_Size_FPL.c file, the code will always call
functions from this iTC_Engine.c to extract the arrays (LUT) to get the corresponding
data and set to each of predefined constant for later use.

EPD EXT2 with Cypress PSoC 4 BLE module 19 [User’s Guide] Rev.01
3.2 Change the different size EPD and image
In main c, you have to set both of dr_eTC_BWb and sz_eTC_epd-size to use the proper driving
waveform
For example, if you attached 2.71” eTC EPD, the code is as follows,
#define USE_EPD_Type dr_eTC_BWb
#define USE_EPD_Size sz_eTC_271
If you attached 2.15” iTC epd, the code should be modified as follows,
#define USE_EPD_Type dr_iTC_BWb
#define USE_EPD_Size sz_iTC_215
images folder:
You can convert any image file to a binary data and put it in this folder.
