Detailed Description

LCD driver interface.

This defines the functions to access a LCD.

Definition at line 196 of file lcd.h.

#include <lcd.h>

Data Fields
int(*	init )(lcd_t *dev, const lcd_params_t *params)
	Initialize LCD controller.
void(*	set_area )(lcd_t *dev, uint16_t x1, uint16_t x2, uint16_t y1, uint16_t y2)
	Set the LCD work area.

Field Documentation

init

int(* lcd_driver::init) (lcd_t *dev, const lcd_params_t *params)

Initialize LCD controller.

Parameters

[in]

dev

Pointer to the selected driver

Returns

0 on success

< 0 value in error

Definition at line 205 of file lcd.h.

set_area

void(* lcd_driver::set_area) (lcd_t *dev, uint16_t x1, uint16_t x2, uint16_t y1, uint16_t y2)

Set the LCD work area.

This function pointer can be NULL if the controller specific driver does not require anything special. In this case the default implementation is used which sets the column addresses and the row addresses of the area including the coordinates of the opposite corner.

Parameters

[in]	dev	Pointer to the selected driver
[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
