Macros
#define	SPI_FLASH_CHIP_SIZE   0x80000
	SPI Flash chip size can not be determined by the chip and therefore must be explicitly set to 512 kbytes.

I2C configuration
#define	I2C0_SPEED   I2C_SPEED_FAST
	I2C bus speed of I2C_DEV(0)
#define	I2C0_SDA   GPIO4
	SDA signal of I2C_DEV(0)
#define	I2C0_SCL   GPIO5
	SCL signal of I2C_DEV(0)

PWM channel configuration
#define	PWM0_GPIOS   { GPIO0, GPIO4, GPIO5 }
	Declaration of the channels for device PWM_DEV(0), at maximum 8 channels.

Macro Definition Documentation

I2C0_SCL

#define I2C0_SCL   GPIO5

SCL signal of I2C_DEV(0)

Definition at line 34 of file periph_conf.h.

I2C0_SDA

#define I2C0_SDA   GPIO4

SDA signal of I2C_DEV(0)

Definition at line 31 of file periph_conf.h.

I2C0_SPEED

#define I2C0_SPEED   I2C_SPEED_FAST

I2C bus speed of I2C_DEV(0)

Definition at line 28 of file periph_conf.h.

PWM0_GPIOS

#define PWM0_GPIOS   { GPIO0, GPIO4, GPIO5 }

Declaration of the channels for device PWM_DEV(0), at maximum 8 channels.

Note

As long as PWM_DEV(0) is not initialized with pwm_init, the GPIOs declared as PWM channels can be used for other purposes.

Definition at line 52 of file periph_conf.h.

SPI_FLASH_CHIP_SIZE

#define SPI_FLASH_CHIP_SIZE   0x80000

SPI Flash chip size can not be determined by the chip and therefore must be explicitly set to 512 kbytes.
