Macro Definition Documentation



System core clock in Hz.

1GHz is an arbitrary value used for compatibility with other platforms.

#define NATIVE_TIMER_MIN_RES   200

Definition at line 38 of file periph_conf.h.


#define QDEC_NUMOF   (8U)

UART configuration.

PWM configuration

QDEC configuration

#define RANDOM_NUMOF   (1U)

Definition at line 45 of file periph_conf.h.


#define SPI_HWCS (   x)    (UINT_MAX - SPI_MAXCS + x)

Hardware chip select access macro.

The amount of available hardware chip select lines depends on the SPI_MAXCS parameter. If the line is actually available at runtime depends of whether a --spi startup parameter with the corresponding SPI device and HWCS-line parameter has been given.

Definition at line 125 of file periph_conf.h.


#define SPI_MAXCS   (4U)

Maximum amount of chip select lines per bus.

Allows up to SPI_MAXCS hardware cable select lines per SPI device. The n-th hardware select line can be used with the SPI_HWCS macro.

Definition at line 114 of file periph_conf.h.


#define SPI_NUMOF   (1U)

Amount of SPI devices.

Allows up to SPI_NUMOF SPI devices with each having up to SPI_MAXCS hardware cable select lines. Assignment to hardware devices can be configured at runtime using the --spi startup parameter.

Can be overridden during compile time with a -DSPI_NUMOF=n flag.
