Detailed Description

Class for Pervasive Displays iTC monochrome touch screens with embedded fast update.

Screen controllers

LCD: proprietary, SPI
touch: proprietary, I2C
fonts: no external Flash

Note: All commands work on the frame-buffer, to be displayed on screen with flush()

Constructor & Destructor Documentation

◆ Screen_EPD_EXT3_Fast()

Screen_EPD_EXT3_Fast::Screen_EPD_EXT3_Fast	(	uint32_t	eScreen_EPD_EXT3,
		pins_t	board )

Constructor with default pins.

Parameters

eScreen_EPD_EXT3	size and model of the e-screen
board	board configuration

Note: Frame-buffer generated by the class; To be used with begin() with no parameter

Member Function Documentation

◆ begin()

void Screen_EPD_EXT3_Fast::begin ( )

virtual

Initialisation.

Note: Frame-buffer generated internally, not suitable for FRAM

Warning: begin() initialises SPI and I2C

Reimplemented from hV_Screen_Buffer.

◆ clear()

void Screen_EPD_EXT3_Fast::clear ( uint16_t colour = myColours.white )

virtual

Clear the screen.

Parameters

colour default = white

Note: Clear next frame-buffer

Reimplemented from hV_Screen_Buffer.

◆ flush()

void Screen_EPD_EXT3_Fast::flush ( )

virtual

Update the display, global update.

Note

Send the frame-buffer to the screen
Refresh the screen
Copy next frame-buffer into old frame-buffer

Implements hV_Screen_Buffer.

◆ flushMode()

uint8_t Screen_EPD_EXT3_Fast::flushMode ( uint8_t updateMode = 0x02 )

Update the display.

Display next frame-buffer on screen and copy next frame-buffer into old frame-buffer

Parameters

updateMode expected update mode, default = UPDATE_FAST

Returns: uint8_t recommended mode

Note: Mode checked with checkTemperatureMode()

◆ regenerate()

void Screen_EPD_EXT3_Fast::regenerate ( uint8_t mode = 0x02 )

Regenerate the panel.

White-to-black-to-white cycle to reduce ghosting

Parameters

mode	default = UPDATE_FAST = fast mode

◆ resume()

void Screen_EPD_EXT3_Fast::resume ( )

Resume after suspend()

Turn SPI on and set all GPIOs levels

◆ suspend()

void Screen_EPD_EXT3_Fast::suspend ( uint8_t suspendScope = 0x01 )

Suspend.

Parameters

suspendScope default = POWER_SCOPE_GPIO_ONLY, otherwise POWER_SCOPE_NONE

Power off and set all GPIOs low

Note: If panelPower is NOT_CONNECTED, POWER_SCOPE_GPIO_ONLY defaults to POWER_SCOPE_NONE

◆ WhoAmI()

String Screen_EPD_EXT3_Fast::WhoAmI ( )

virtual

Who Am I.

Returns: Who Am I string

Implements hV_Screen_Buffer.
