Detailed Description

template<typename I>
class InterfacePCD8544< I >

Class implements interface functions to PCD8544 displays.

Definition at line 43 of file lcd_pcd8544.h.

Constructor & Destructor Documentation

InterfacePCD8544()

template<typename I>

template<typename... Args>

InterfacePCD8544< I >::InterfacePCD8544 ( NanoDisplayBase< InterfacePCD8544< 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)

Member Function Documentation

commandStart()

template<class I >

void InterfacePCD8544< I >::commandStart

(

)

Starts communication with LCD display in command mode.

To stop communication use m_intf.end().

Definition at line 73 of file lcd_pcd8544.inl.

nextBlock()

template<class I >

void InterfacePCD8544< I >::nextBlock

(

)

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

For PCD8544 it does nothing, while for sh1106 the function moves cursor to next page.

Definition at line 48 of file lcd_pcd8544.inl.

setDataMode()

template<class I >

void InterfacePCD8544< 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 65 of file lcd_pcd8544.inl.

startBlock()

template<class I >

void InterfacePCD8544< 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 PCD8544 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().
