Function Documentation

ili9341_fill()

void ili9341_fill	(	const ili9341_t *	dev,
		uint16_t	x1,
		uint16_t	x2,
		uint16_t	y1,
		uint16_t	y2,
		uint16_t	color
	)

Fill a rectangular area with a single pixel color.

the rectangular area is defined as x1 being the first column of pixels and x2 being the last column of pixels to fill. similar to that, y1 is the first row to fill and y2 is the last row to fill.

Parameters

[in]	dev	device descriptor
[in]	x1	x coordinate of the first corner
[in]	x2	x coordinate of the opposite corner
[in]	y1	y coordinate of the first corner
[in]	y2	y coordinate of the opposite corner
[in]	color	single color to fill the area with

ili9341_init()

int ili9341_init	(	ili9341_t *	dev,
		const ili9341_params_t *	params
	)

Setup an ili9341 display device.

Parameters

[out]	dev	device descriptor
[in]	params	parameters for device initialization

ili9341_invert_off()

void ili9341_invert_off

(

const ili9341_t *

dev

)

Disable color inversion.

Parameters

[in]

dev

device descriptor

ili9341_invert_on()

void ili9341_invert_on

(

const ili9341_t *

dev

)

Invert the display colors.

Parameters

[in]

dev

device descriptor

ili9341_pixmap()

void ili9341_pixmap	(	const ili9341_t *	dev,
		uint16_t	x1,
		uint16_t	x2,
		uint16_t	y1,
		uint16_t	y2,
		const uint16_t *	color
	)

Fill a rectangular area with an array of pixels.

the rectangular area is defined as x1 being the first column of pixels and x2 being the last column of pixels to fill. similar to that, y1 is the first row to fill and y2 is the last row to fill.

Note

color must have a length equal to (x2 - x1 + 1) * (y2 - y1 + 1)

Parameters

[in]	dev	device descriptor
[in]	x1	x coordinate of the first corner
[in]	x2	x coordinate of the opposite corner
[in]	y1	y coordinate of the first corner
[in]	y2	y coordinate of the opposite corner
[in]	color	array of colors to fill the area with

ili9341_read_cmd()

void ili9341_read_cmd	(	const ili9341_t *	dev,
		uint8_t	cmd,
		uint8_t *	data,
		size_t	len
	)

Raw read command.

Precondition

len > 0

Parameters

[in]	dev	device descriptor
[in]	cmd	command
[out]	data	data from the device
[in]	len	length of the returned data

ili9341_write_cmd()

void ili9341_write_cmd	(	const ili9341_t *	dev,
		uint8_t	cmd,
		const uint8_t *	data,
		size_t	len
	)

Raw write command.

Parameters
