Detailed Description

API for configuring and manipulating ILI9341 Display Controller driver.

Function Documentation

ili9341_init()

void ili9341_init	(	ili9341_cfg_t *	cfg,
		gl_driver_t *__generic_ptr	driver,
		ili9341_t *	ctx
	)

This function initializes ILI9341 Display Controller context object to default values and allows driver interface object to be linked with ILI9341 Display Controller driver functions.

Parameters

[in]	cfg	: ILI9341 configuration object. See ili9341_cfg_t structure definition for detailed explanation.
[out]	driver	: Graphics Library driver interface object. See gl_driver_t structure definition and gl_set_driver function for detailed explanation.
[out]	ctx	Initialized ILI9341 context structure. See ili9341_t for more information about the context structure.

Returns

Nothing.

ili9341_default_cfg()

void ili9341_default_cfg

(

ili9341_cfg_t *

cfg

)

This function initializes PWM default configuration.

Parameters

[in]

cfg

: ILI9341 configuration object. See ili9341_cfg_t structure definition for detailed explanation.

Return values

Nothing.

ili9341_write_command()

void ili9341_write_command

(

uint8_t

command

)

This function sends command to ILI9341 Display Controller.

Parameters

[in]

command

: command to be sent. See ILI9341 Display Controller Commands for command list.

Returns

Nothing.

ili9341_write_param()

void ili9341_write_param

(

uint8_t

param

)

This function sends data to ILI9341 Display Controller.

Parameters

[in]

param

: data to be sent.

Returns

Nothing.

ili9341_get_display_width()

uint16_t ili9341_get_display_width

(

)

This function returns the width of the ILI9341 controller based display.

Returns

Display width.

ili9341_get_display_height()

uint16_t ili9341_get_display_height

(

)

This function returns the height of the ILI9341 controller based display.

Returns

Display height.

ili9341_backlight_control_init()

void ili9341_backlight_control_init	(	ili9341_cfg_t *	cfg,
		ili9341_t *	ctx
	)

Initialize PWM module for controlling display backlight intensity.

Returns

Nothing.

ili9341_set_backlight_intensity()

void ili9341_set_backlight_intensity	(	float	intensity,
		ili9341_t *	ctx
	)

Set active intensity of display controller.

Returns

Nothing.

ili9341_rotate()

void ili9341_rotate	(	ili9341_t *	ctx,
		tp_rotate_t *	rotate
	)

This function is necessary for interfacing with touch panel library as it's address is stored in tp_drv_t driver structure during the ILI9341 context initialization.

Parameters

[out]	ctx	Initialized ILI9341 context structure. See ili9341_t for more information about the context structure.
[in]	rotate	Structure with desired orientation set.

Returns

Nothing.
