EPD EXT2 with Cypress PSoC 4 BLE module 3 [User’s Guide] Rev.01
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.

1.2.2 EPD Extension Board Gen2 (EXT2 board)
Figure 1-1 EPD Extension Board Gen2 (front view)
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.

-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

2.1.3 Getting started with EXT2 kit
Please check with the backside of EXT2 board. You will find a table for adjusting the J7 of 8
positions of DIP switch.

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.
