SYSTEM ARCHITECURE

System support

Host operating system: linux(ubuntu)、OpenWrt、windows(windows 7 or windows 10)

Waveform mode

There are six Waveform mode for image update and short name as below table. The mode parameter will use in update command.

mode 0 mode 1 mode 2 mode 3 mode 4 mode 5
INIT DU GC16 GCC16 A2 GL16

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

GCC16( Global clear update WF) :

Grayscale Clear, 16 Levels A "more flashy" waveform used for 16 level grayscale images. All the pixels are updated or cleared.
This provides the best image appearance.

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.

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.

Push image application
