i2c/spi ssd1306 library hardware abstraction layer

ssd1306 library hardware abstraction layer

Macro Definition Documentation

◆ LCDINT_TYPES_DEFINED

#define LCDINT_TYPES_DEFINED

Macro informs if lcdint_t type is defined

Definition at line 61 of file io.h.

◆ ssd1306_swap_data

#define ssd1306_swap_data	(	a,
		b,
		type
	)	{ type t = a; a = b; b = t; }

swaps content of a and b variables of type type

Definition at line 69 of file io.h.

Typedef Documentation

◆ lcdint_t

typedef int lcdint_t

internal int type, used by ssd1306 library. Important for uC with low SRAM

Definition at line 63 of file io.h.

◆ lcduint_t

typedef unsigned int lcduint_t

internal int type, used by ssd1306 library. Important for uC with low SRAM

Definition at line 65 of file io.h.

Function Documentation

◆ ssd1306_platform_i2cInit()

void ssd1306_platform_i2cInit	(	int8_t	busId,
		uint8_t	addr,
		ssd1306_platform_i2cConfig_t *	cfg
	)

Initializes i2c interface for platform being used.

Initializes i2c interface for platform being used. i2c implementation depends on platform.

Parameters

busId	i2c bus number. Some platforms have several i2c buses. so, this argument identifies bus to use. For several platforms busId is not used. If you want to use default i2c bus for specific platform, please pass -1.
addr	i2c address of oled driver, connected to i2c bus. If you want to use default i2c display address, please, pass 0.
cfg	Specify scl and sda for the platform. If you want to use default pin numbers, please pass -1 for both members.

◆ ssd1306_platform_spiInit()

void ssd1306_platform_spiInit	(	int8_t	busId,
		int8_t	cesPin,
		int8_t	dcPin
	)

Initializes spi interface for platform being used.

Initializes spi interface for platform being used. spi implementation depends on platform.
