Detailed Description

template<typename I>
class InterfaceILI9341< I >

Class implements interface functions to ILI9341 displays.

Definition at line 43 of file lcd_ili9341.h.

Constructor & Destructor Documentation

InterfaceILI9341()

template<typename I>

template<typename... Args>

InterfaceILI9341< I >::InterfaceILI9341 ( NanoDisplayBase< InterfaceILI9341< I >> &  base, int8_t  dc, Args &&...  data  )

inline

Creates instance of interface to LCD display.

Parameters

base	Reference to base class, which represents Display
dc	Data/command control pin number, for i2c communication should be -1
data	variable argument list, accepted by platform interface (PlatformI2c, PlatformSpi)

Definition at line 54 of file lcd_ili9341.h.

Member Function Documentation

commandStart()

template<class I >

void InterfaceILI9341< I >::commandStart

(

)

Starts communication with LCD display in command mode.

To stop communication use m_intf.end().

Definition at line 77 of file lcd_ili9341.inl.

invertMode()

template<class I >

void InterfaceILI9341< I >::invertMode

(

)

Switches display to inverted mode (sends INVON command).

Use this to re-enable inversion if normalMode() was called.

See also

normalMode()

Definition at line 134 of file lcd_ili9341.inl.

nextBlock()

template<class I >

void InterfaceILI9341< I >::nextBlock

(

)

Switches to the start of next RAM page for the block, specified by startBlock().

For ILI9341 it does nothing, while for sh1106 the function moves cursor to next page.

Definition at line 59 of file lcd_ili9341.inl.

normalMode()

template<class I >

void InterfaceILI9341< I >::normalMode

(

)

Switches display to normal (non-inverted) mode (sends INVOFF command).

See also

invertMode()

Definition at line 126 of file lcd_ili9341.inl.

rotateOutput()

template<class I >

void InterfaceILI9341< I >::rotateOutput

(

uint8_t

rotate

)

Sets rotation of all output functions.

Sets rotation of all output functions. 0 - no rotation, 1 - change by 90 degrees Actually doesn't change screen orientation, only rotates primitives being output

Parameters

rotate

enable (1) of disable (0)

Warning

experimental feature, may work incorrectly

Definition at line 120 of file lcd_ili9341.inl.

setDataMode()

template<class I >

void InterfaceILI9341< I >::setDataMode

(

uint8_t

mode

)

Enables either data or command mode on SPI bus.

Parameters

mode	1 to enable data mode, or 0 to enable command mode

Definition at line 69 of file lcd_ili9341.inl.

setRotation()

template<class I >

void InterfaceILI9341< I >::setRotation

(

uint8_t

rotation

)

Sets screen orientation (rotation)

Sets screen orientation (rotation):

• 0 — normal (portrait)
• 1 — 90° CW (landscape)
• 2 — 180° CW (portrait inverted)
• 3 — 270° CW (landscape inverted)

Parameters

rotation

screen rotation (0–3)

Definition at line 86 of file lcd_ili9341.inl.

startBlock()

template<class I >

void InterfaceILI9341< I >::startBlock	(	lcduint_t	x,
		lcduint_t	y,
		lcduint_t	w
	)

Sets block in RAM of lcd display controller to write data to.

Sets block in RAM of lcd display controller to write data to. For ILI9341 it uses horizontal addressing mode, while for sh1106 the function uses page addressing mode. Width can be specified as 0, thus the library will set the right boundary to region of RAM block to the right column of the display.

Parameters

x	- column (left region)
y	- row (top region)
w	- width of the block in pixels to control

Warning

- this function initiates session (i2c or spi) and does not close it. To close session, please, call endBlock().
