Macro Definition Documentation

◆ BLADERF_TRIGGER_REG_ARM

#define BLADERF_TRIGGER_REG_ARM ((uint8_t)(1 << 0))

Trigger control register "Arm" bit

This bit arms (i.e., enables) the trigger controller when set to 1. Samples will be gated until the "Fire" bit has been asserted.

A 0 in this bit disables the trigger controller. Samples will continue to flow as they normally do in this state.

Definition at line 3669 of file libbladeRF.h.

◆ BLADERF_TRIGGER_REG_FIRE

#define BLADERF_TRIGGER_REG_FIRE ((uint8_t)(1 << 1))

Trigger control register "Fire" bit

For a master, this bit causes a trigger to be sent to all slave devices. Once this trigger is received (the master "receives" it immediately as well), devices begin streaming samples.

This bit has no effect on slave devices.

Definition at line 3680 of file libbladeRF.h.

◆ BLADERF_TRIGGER_REG_LINE

#define BLADERF_TRIGGER_REG_LINE ((uint8_t)(1 << 3))

Trigger control registers "line" bit

This is a read-only register bit that denotes the current state of the the trigger signal.

Definition at line 3698 of file libbladeRF.h.

◆ BLADERF_TRIGGER_REG_MASTER

#define BLADERF_TRIGGER_REG_MASTER ((uint8_t)(1 << 2))

Trigger control register "Master" bit

Selects whether the device is a trigger master (1) or trigger slave (0). The trigger master drives the trigger signal as an output.

Slave devices configure the trigger signal as an input.

	)

Read trigger control register

Parameters
