EPD-130 Application guide
This application provide user a way that image full/partial update for EPD-130 panel. user should follow the different command parameter to load or display image or using .bat script combined with load and display command. Application only support on Windows platform(Windows 7、Windows 10)。

SYSTEM ARCHITECURE
Panel type
- EPD-130R : The panel has black and white color.
- EPD-130B : The panel has black、white and red color.
Waveform mode
There are six Waveform mode for image update and short name as below table. Waveform mode suit to EPD-130B panel type and mode parameter will use in display command.
EPD-130B waveform mode table
| mode 0 | mode 1 | mode 2 | mode 3 | mode 4 | mode 5 |
| INIT | DU | GC16 | GL16 | A2 | DU4 |
INIT(Global update WF) :
- Initialize is used to completely clear the display, if it's left in an unknown state (i.e. if the previous image has been lost by a re-boot)
DU(Local update WF) :
- Direct update Non-flashing waveform that can be used to update. it can update any changed graytone pixel to black or white only.
GC16(Global update WF) :
- Grayscale clear, 16 levels A "flashy" waveform used for 16 level grayscale images. All the pixels are updated or cleared
GL16(Local update WF when white to white , Global update when 16 gray levels) :
- The GL16 waveform is used to update anti-aliased text with reduced flash. GL16 should bed used only with Full Display Update.
- The entire display except pixels staying in white will update as the new image is written. The GL16 waveform has 16 unique gray levels.
A2(Local update WF) :
- animation, 2 Levels is a non-flashing waveform that can be used for fast updates and simple animation.
- This wave form support black & white updates only.
- image quality and ghosting is reduced in exchange for the response time.
DU4(Local update WF) :
- A fast update time(simlar to DU), non-flashy waveform.
- This mode supports transitions from any graytone to graytone 0(Black),5,10.15(White).
- The combination of fast update time and four graytone make it useful for anti-aliased text in menus
EPD-130R waveform mode
It's only supported mode 0 and 1
Mode 0 :Showing black and white elements
Mode 1 :Showing red element in picture.
Push image application
Hardware and software prepare
Follow steps and picture below to setup the hardware
1. Turn to back of mainboard and Connected EPD FPC to mainboard
2. Connected micro USB cable to mainboard USB2(CN5) the other side connect to desktop/laptop usb port
3. Download and unzip EPD-132R_CLIv4_tool
4. Open windows command line
5. Change current directory to user's Adv_CLI_v4 tool directory on command line window
6. User can find IT8951_USB_Cmd.exe application in Adv_CLI_v4
The command parameter in detail as below
Load image
a. Load image :Load selected image file to image buffer. Only supports bmp and jpg type.
Command format: IT8951_USB_Cmd.exe -load [file name]
b. Display : Refresh the assigned range of EPD (according to the image buffer and chosen mode)
IT8951_USB_Cmd.exe -display -nowait [x] [y] [width] [height] [mode]
The x, y is the start coordinates and width, height is update range but it can not exceed the resolution. mode see Section 1.3 waveform mode
Full update
x、y start coordinates is given in (0, 0) , width 、height is given in (1600 , 1200).
In EPD-130B panel type. The usually full update command as below.
IT8951_USB_Cmd.exe -display -nowait 0 0 1600 1200 2
In EPD-130R panel type. The usually full update command as below.
IT8951_USB_Cmd.exe -display -nowait 0 0 1600 1200 0
IT8951_USB_Cmd.exe -display -nowait 0 0 1600 1200 1
Partial update
x, y start coordinate and the width、height depends on user's defined.
In EPD-130B panel type.
Below command is defined start coordinate in (0, 800) and width、height is defined in (1600 , 400).
IT8951_USB_Cmd.exe -display -nowait 0 800 1600 400 2
In EPD-130R panel type
Below command is defined start coordinate in (0, 200) and width、height is defined in (800 , 600).
IT8951_USB_Cmd.exe -display -nowait 0 200 800 600 0
IT8951_USB_Cmd.exe -display -nowait 0 200 800 600 1
Note Panel resolution is 1600 x 1200
