Macro Definition Documentation

◆ GPIO_PIN

#define GPIO_PIN	(		x,
			y )

Value:

((gpio_t)((x<<4) | y))

Definition at line 32 of file periph_cpu.h.

◆ HAVE_GPIO_DIR_T

#define HAVE_GPIO_DIR_T

Override values for pin direction configuration.

Definition at line 56 of file periph_cpu.h.

◆ HAVE_GPIO_T

#define HAVE_GPIO_T

Overwrite the default gpio_t type definition.

Definition at line 30 of file periph_cpu.h.

◆ PERIPH_SPI_NEEDS_INIT_CS

#define PERIPH_SPI_NEEDS_INIT_CS 1

Definition at line 149 of file periph_cpu.h.

◆ PERIPH_SPI_NEEDS_TRANSFER_BYTE

#define PERIPH_SPI_NEEDS_TRANSFER_BYTE 1

declare needed generic SPI functions

Definition at line 146 of file periph_cpu.h.

◆ PERIPH_SPI_NEEDS_TRANSFER_REG

#define PERIPH_SPI_NEEDS_TRANSFER_REG 1

Definition at line 147 of file periph_cpu.h.

◆ PERIPH_SPI_NEEDS_TRANSFER_REGS

#define PERIPH_SPI_NEEDS_TRANSFER_REGS 1

Definition at line 148 of file periph_cpu.h.

◆ SPI_HWCS

#define SPI_HWCS ( x )

Value:

(UINT_MAX - 1)

Override SPI hardware chip select macro.

As of now, we do not support HW CS, so we always set it to a fixed value

Definition at line 121 of file periph_cpu.h.
