Member Function Documentation

check_display_device_compatibility()

void ST7735::check_display_device_compatibility ( struct_ConfigGraphicWidget framebuffer_cfg )

virtual

A pure virtual member function. Each device must implement this method and check the compatibility of the widget parameter with the its physical limitations.

Parameters

framebuffer_cfg

the widget configuration data

Implements GraphicDisplayDevice.

clear_device_screen_buffer()

void ST7735::clear_device_screen_buffer

(

ColorIndex

color_index = ColorIndex::BLACK

)

fill the internal ST7735 screen buffer with the given color. Default to BLACK, clear the internal buffer

Parameters

color_index

Here is the call graph for this function:

enable_sleep()

void ST7735::enable_sleep

(

bool

enable

)

turn the display in sleep mode on/off

Parameters

enable

set_rotation_and_color()

void ST7735::set_rotation_and_color

(

struct_ConfigST7735

device_config

)

set the actual position of the display

set rotation and color

Parameters

device_config

the device configuration file

Here is the caller graph for this function:

show()

void ST7735::show ( Canvas * canvas, const uint8_t anchor_x, const uint8_t anchor_y )

virtual

A pure virtual member function. It transfers the pixel buffer to the a part of display screen buffer starting at the (anchor_x, anchor_y) coordinates of the screen , expressed in pixel. This method takes into account the specific addressing scheme and memory structure of the actual display device.

Parameters

canvas	a pointer to the canvas that contains the buffer to be displayed
anchor_x	the x(horizontal) starting position of the frame within the display screen,(in pixel)
anchor_y	the y(vertical) starting position of the frame within the display screen,(in pixel)

Implements GraphicDisplayDevice.
