public enum Command : byte

Fields

DataStartTransmission1 = 16

Start a data pixel value writing.

The command define as follows: The register is indicates that user start to transmit data, then write to SRAM. While data transmission complete, user must send command 11H. Then chip will start to send data/VCOM for panel. In BW mode, this command writes “OLD” data to SRAM. In BWR mode, this command writes “B/W” data to SRAM. In Program mode, this command writes “OTP” data to SRAM for programming.

DataStartTransmission2 = 19

Start a data pixel value writing.

The command define as follows: The register is indicates that user start to transmit data, then write to SRAM. While data transmission complete, user must send command 11H. Then chip will start to send data/VCOM for panel. In B/W mode, this command writes “NEW” data to SRAM. In B/W/Red mode, this command writes “RED” data to SRAM.

DeepSleepMode = 7

Sets the screen in deep sleep mode.

The command define as follows: After this command is transmitted, the chip would enter the deep-sleep mode to save power. The deep sleep mode would return to standby by hardware reset.

DisplayRefresh = 18

Sets the settings for the screen.

The command defines as : While users send this command, driver will refresh display (data/VCOM) base on SRAM data and LUT. After display refresh command, BUSY_N signal will become “0”.

IntervalSetting = 80

VCOM and DATA interval setting.

Refer to the datasheet for detailed information about the command and its parameters.

PanelSetting = 0

Sets the settings for the screen.

Refer to the datasheet for detailed information about the command and its parameters.

PowerOff = 2

Power off command.

After power off command, driver will power off base on power off sequence. After power off command, BUSY_N signal will drop from high to low. When finish the power off sequence, BUSY_N singal will rise from low to high. Power off command will turn off charge pump, T-con, source driver, gate driver, VCOM, temperature sensor, but register and SRAM data will keep until VDD off.

PowerOn = 4

Power on command.

After power on command, driver will power on base on power on sequence. After power on command, BUSY_N signal will drop from high to low. When finishing the power on sequence, BUSY_N signal will rise from low to high.

PowerSaving = 227

Defines power saving settings.

This command is set for saving power during fresh period. If the output voltage of VCOM / Source is from negative to positive or from positive to negative, the power saving mechanism will be activated. The active period width is defined by the following two parameters. - VCOM_W[3:0]: VCOM power saving width (unit = line period) - SD_W[3:0]: Source power saving width (unit = 660nS).

ResolutionSetting = 97

Define screen resolution setting.

This command defines as follow: HRES[7:3]: Horizontal Display Resolution (first data) VRES[8:0]: Vertical Display Resolution (second and third data) Active channel calculation: - GD: First active gate = G0(Fixed); LAST active gate = first active + VRES[8:0] – 1 - SD: First active source = S0(Fixed); LAST active source = first active+HRES[7:3] * 8 – 1.

TCONSetting = 96

Defines non-overlap period of Gate and Source.

Refer to the datasheet for detailed information about the command and its parameters.
