In a most cases, higher-level routines should be used. These routines are only intended to support development and testing.
Use these routines with great care, and be sure to reference the relevant schematics, data sheets, and source code (i.e., firmware and hdl).
Be careful when mixing these calls with higher-level routines that manipulate the same registers/settings.
These functions are thread-safe.

#define BLADERF_GPIO_8BIT_MODE (1 << 20) |
Enable 8bit sample mode
Definition at line 1377 of file bladeRF1.h.
#define BLADERF_GPIO_AGC_ENABLE (1 << 18) |
AGC enable control bit
Definition at line 1384 of file bladeRF1.h.
#define BLADERF_GPIO_COUNTER_ENABLE (1 << 9) |
Counter mode enable
Setting this bit to 1 instructs the FPGA to replace the (I, Q) pair in sample data with an incrementing, little-endian, 32-bit counter value. A 0 in bit specifies that sample data should be sent (as normally done).
This feature is useful when debugging issues involving dropped samples.
Definition at line 1330 of file bladeRF1.h.
#define BLADERF_GPIO_FEATURE_SMALL_DMA_XFER (1 << 7) |
This GPIO bit configures the FPGA to use smaller DMA transfers (256 cycles instead of 512). This is required when the device is not connected at Super Speed (i.e., when it is connected at High Speed).
However, the caller need not set this in bladerf_config_gpio_write() calls. The library will set this as needed; callers generally do not need to be concerned with setting/clearing this bit.

#define BLADERF_GPIO_LMS_RX_ENABLE (1 << 1) |
Enable LMS receive
Definition at line 1298 of file bladeRF1.h.
#define BLADERF_GPIO_LMS_TX_ENABLE (1 << 2) |
Enable LMS transmit
Definition at line 1305 of file bladeRF1.h.
#define BLADERF_GPIO_PACKET (1 << 19) |
Enable Packet mode
Definition at line 1372 of file bladeRF1.h.
#define BLADERF_GPIO_PACKET_CORE_PRESENT (1 << 28) |
Packet capable core present bit.
Definition at line 1414 of file bladeRF1.h.
#define BLADERF_GPIO_RX_HB_ENABLE (1 << 5) |
Switch to use RX high band (1.5GHz - 3.8GHz)
Definition at line 1356 of file bladeRF1.h.
#define BLADERF_GPIO_RX_LB_ENABLE (2 << 5) |
Switch to use RX low band (300M - 1.5GHz)
Definition at line 1349 of file bladeRF1.h.
#define BLADERF_GPIO_RX_MUX_MASK (0x7 << BLADERF_GPIO_RX_MUX_SHIFT) |
Bit mask representing the rx mux selection
Definition at line 1337 of file bladeRF1.h.
#define BLADERF_GPIO_RX_MUX_SHIFT 8 |
Starting bit index of the RX mux values in FX3 <-> FPGA GPIO bank
Definition at line 1342 of file bladeRF1.h.
#define BLADERF_GPIO_TIMESTAMP (1 << 16) |
Enable-bit for timestamp counter in the FPGA
Definition at line 1389 of file bladeRF1.h.
#define BLADERF_GPIO_TIMESTAMP_DIV2 (1 << 17) |
Timestamp 2x divider control.
By default (value = 0), the sample counter is incremented with I and Q, yielding two counts per sample.
Set this bit to 1 to enable a 2x timestamp divider, effectively achieving 1 timestamp count per sample.
Definition at line 1406 of file bladeRF1.h.
#define BLADERF_GPIO_TX_HB_ENABLE (1 << 3) |
Switch to use TX high band (1.5GHz - 3.8GHz)
Definition at line 1319 of file bladeRF1.h.
#define BLADERF_GPIO_TX_LB_ENABLE (2 << 3) |
Switch to use TX low band (300MHz - 1.5GHz)
Definition at line 1312 of file bladeRF1.h.
API_EXPORT int CALL_CONV bladerf_dac_read | ( | struct bladerf * | dev, |
uint16_t * | val | ||
) |
Read value from VCTCXO trim DAC.
This is similar to bladerf_get_vctcxo_trim(), except that it returns the current trim DAC value, as opposed to the calibration value read from flash.
Use this if you are trying to query the value after having previously made calls to bladerf_dac_write().
dev | Device handle | |
[out] | val | Value to read from VCTCXO trim DAC |
API_EXPORT int CALL_CONV bladerf_dac_write | ( | struct bladerf * | dev, |
uint16_t | val | ||
) |
Write value to VCTCXO trim DAC.
This should not be used when the VCTCXO tamer is enabled.
dev | Device handle | |
[in] | val | Value to write to VCTCXO trim DAC |
API_EXPORT int CALL_CONV bladerf_lms_get_dc_cals | ( | struct bladerf * | dev, |

This is generally intended for applying a set of known values resulting from a previous run of the LMS autocalibrations.
dev | Device handle | |
