Introduction
This document will teach you how to use EPD-EVK.
Preparation
EVK Components
| Item | Description |
|---|---|
| 1 | EPD |
| 2 | EVK mainboard |
| 3 | Power adapter and cable |
| 4 | ED22 board |
| 5 | ED22 micro USB cable |
| 6 | 10 pin FFC cable |
| 7 | 2.4G Wi-Fi antenna |
2.4G Wi-Fi AP
Prepare a 2.4G Wi-Fi AP.
Win7 PC
Prepare a win7 PC.
Setup TFTP server
- Make sure PC connect to 2.4G Wi-Fi AP and get IP address
- Recommend used tftpd64
- Set the process reference link https://www.youtube.com/watch?v=YdVEonLMWYs
Python Environment Setup
- Download and install Python (must use Python version 2.7.x)
- Set the variables of Widows environment path: add “C:\Python27;C:\Python27\Scripts” to path
- Download and install python PIL package
- Download and unzip picture transformation tool "BmpToPixel_D73.py"
Bmp Image To EPD Format
- Run BmpToPixel_D73.py <source BMP image filename> <output filename> in cmd window
- source BMP image filename: the image file to be converted
- output filename: converted file name(recommend to use "esl" as the extension)
- Bmp size must comply with EPD resolution 1600 x 1200
- Bmp file: mono color/16 color/256 color/24bits bitmap format
- Ex: BmpToPixel_D73.py EVK_03.bmp EVK_03.esl
- Copy output files to tftp Base Directory
WISE-ED22 Setup
- Download and install WISE-ED22 driver
- Connected to PC via a micro USB cable, the Device Manager will appear mbed Serial Port
EVK Setup
Hardware Setup
Follow steps and picture below to setup the hardware
- Connected EPD FPC to mainboard
- Connected Wi-Fi antenna to mainboard
- Connected ED22 board to mainboard via FFC cable
- Connected ED22 board to PC via micro USB cable
- Connected power cable to mainboard
Command Console Setting
Start a serial tool(use tera term in this), and make the communication setting as shown below.
EVK Start
Press “RST” button, the screen will show as below
Example : Download and Refresh Image
Example Architecture
The example architecture is as below
Launch TFTP Service
- PC join to Wi-Fi AP
- Lunch tftpd64.exe and select "Tftp Server" tab
- Check image folder, image file size must be 960000 byte
- Select tftp server IP
EVK Join to Wi-Fi AP
- EVK operates in command mode, you must start a serial tool.
- type join <SSID> <encryption> [key]
- SSID, encryption protocol and key consistent with Wi-Fi AP setting
- Ex: join RT66 wpa2_aes 12345678
- Get IPv4 IP if join successful
Download Images to Flash
tftp <ip> <filename> <flash index> [-r]
- ip: tftp server ip
- filename: image file name
- flash index: range 0~3, that have maximum 4 images(0~3) be saved in flash
- -r : immediate refresh after download complete
- Ex: tftp 192.168.8.178 example_2.esl 1 -r
Refresh Image
epd_disp <-f flash index | -i internal image index>
- -f: display image that read from flash, range 0~3
- -i: display internally generated image, range 0~4
0: fully black
1: full white
2: full red
3: black/white/red vertical stripes
4: black/white/red horizontal stripes - Ex: epd_disp -f 1
- Ex: epd_disp -i 4

BLE-WiFi Introducer Service
Ble-WiFi introducer service is a demonstration that set SSID and password to join network by phone. EVK will launch a BLE GATT server and advertise itself.
Then you need to manipulate on your phone.
Step 1: Install and launch the BLE Scanner app on iOS or Android.
Step 2: Pull down the screen to rescan devices and it will list nearby BLE devices. Find the “WiFiInt” device and press CONNECT button.
Step 3: If the connection is successful, you can see the picture below. Press the "CUSTOM SERVICE" button.
Step 4: Find the UUID: ACA0EF7C-EEAA-48AD-9508-19A6F6B356 for SSID characteristic.
Step 5: Find the UUID: 40B7DE33-93E4-4C8B-A876-D833B415A6CE for Password characteristic then procedure as Step4.
