Waveform mode
There are six Waveform mode for image update and short name as below table. This parameter will appear in update command variable.
| 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
Push image application
Follow steps and picture below to setup the hardware
1. Connected EPD FPC to mainboard
2. Connected micro USB cable to mainboard USB2(CN2) the other side connect to desktop/laptop usb port
3. Download and unzip EPD-132R_CLI_tool
4. unzip download package and 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
a. Load image >Load selected image file to image buffer. Only supports bmp and jpg type.
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, width, height is update range but it can not exceed the resolution
Note The panel resolution is 1600 x 1200
