## Function Documentation

## bladerf_expansion_gpio_dir_masked_write()

API_EXPORT int CALL_CONV bladerf_expansion_gpio_dir_masked_write | ( | struct bladerf * | dev,
|  | uint32_t | mask,
|  | uint32_t | outputs )

Configure the direction of the specified expansion GPIO pins

This function alleviates the need for the caller to perform a read-modify-write sequence. The supplied mask is used by the FPGA to perform the required RMW operation.

Parameters

  | dev | Device handle
  [in] | mask | Bitmask of pins to configure
  [in] | outputs | Pins set to '1' will be configured as outputs. Pins set to '0' will be configured as inputs.

For example, to configure XB200 pins J16-1 and J16-2 and pins J16-4 and J16-5 as inputs:

const uint32_t pins_to_config =
BLADERF_XB200_PIN_J16_1 |
BLADERF_XB200_PIN_J16_2 |
BLADERF_XB200_PIN_J16_3 |
BLADERF_XB200_PIN_J16_4;
const uint32_t output_pins =
BLADERF_XB200_PIN_J16_1 |
BLADERF_XB200_PIN_J16_2;
int status = bladerf_expansion_gpio_masked_write(dev,
pins_to_config,
output_pins);

Returns

## bladerf_expansion_gpio_dir_read()

API_EXPORT int CALL_CONV bladerf_expansion_gpio_dir_read | ( | struct bladerf * | dev,
|  | uint32_t * | outputs )

Read the expansion GPIO direction register

Parameters

  | dev | Device handle
  [out] | outputs | Pins configured as outputs will be set to '1'. Pins configured as inputs will be set to '0'.

Returns
  0 on success, value from Error codes list on failure

## bladerf_expansion_gpio_dir_write()

API_EXPORT int CALL_CONV bladerf_expansion_gpio_dir_write | ( | struct bladerf * | dev,
|  | uint32_t | outputs )

Write to the expansion GPIO direction register.

Callers should be sure to perform a read-modify-write sequence to avoid accidentally clearing other GPIO bits that may be set by the library internally.

Consider using bladerf_expansion_gpio_dir_masked_write() instead.

Parameters

  | dev | Device handle
  [in] | outputs | Pins set to '1' will be configured as outputs. Pins set to '0' will be configured as inputs.

Returns
  0 on success, value from Error codes list on failure

## bladerf_expansion_gpio_masked_write()

API_EXPORT int CALL_CONV bladerf_expansion_gpio_masked_write | ( | struct bladerf * | dev,
|  | uint32_t | mask,
|  | uint32_t | value )

Write values to the specified GPIO pins

This function alleviates the need for the caller to perform a read-modify-write sequence. The supplied mask is used by the FPGA to perform the required RMW operation.

Parameters

  | dev | Device handle
  [in] | mask | Mask of pins to write
  [in] | value | Value to write.

For example, to set XB200 pins J16-1 and J16-2, and clear J16-4 and J16-5:

const uint32_t pins_to_write =
BLADERF_XB200_PIN_J16_1 |
BLADERF_XB200_PIN_J16_2 |
BLADERF_XB200_PIN_J16_3 |
BLADERF_XB200_PIN_J16_4;
const uint32_t values_to_write =
BLADERF_XB200_PIN_J16_1 |
BLADERF_XB200_PIN_J16_2;
int status = bladerf_expansion_gpio_masked_write(dev,
pins_to_write,
values_to_write);

Returns
  0 on success, value from Error codes list on failure

## bladerf_expansion_gpio_read()

API_EXPORT int CALL_CONV bladerf_expansion_gpio_read | ( | struct bladerf * | dev,
|  | uint32_t * | val )

Read the state of expansion GPIO values

Parameters

  | dev | Device handle
  [out] | val | Value of GPIO pins

Returns
  0 on success, value from Error codes list on failure

## bladerf_expansion_gpio_write()

API_EXPORT int CALL_CONV bladerf_expansion_gpio_write | ( | struct bladerf * | dev,
|  | uint32_t | val )

Write expansion GPIO pins.

Callers should be sure to perform a read-modify-write sequence to avoid accidentally clearing other GPIO bits that may be set by the library internally.

Consider using bladerf_expansion_gpio_masked_write() instead.

Parameters

  | dev | Device handle
  [in] | val | Data to write to GPIO pins

Returns
  0 on success, value from Error codes list on failure
