Function Documentation

pulsar_adc_init()

int32_t pulsar_adc_init	(	struct pulsar_adc_dev **	device,
		struct pulsar_adc_init_param *	init_param )

Initialize the device.

Parameters

device	- The device structure.
init_param	- The structure that contains the device initial parameters.

Returns

0 in case of success, negative error code otherwise.

pulsar_adc_read_data()

int32_t pulsar_adc_read_data	(	struct pulsar_adc_dev *	dev,
		uint32_t *	buf,
		uint16_t	samples )

Read conversion results from device.

Parameters

dev	- The device structure.
buf	- Buffer to hold the conversion results data
samples	- number of samples to read

Returns

0 in case of success, negative error code otherwise.

pulsar_adc_remove()

int32_t pulsar_adc_remove

(

struct pulsar_adc_dev *

dev

)

Free the resources allocated by pulsar_adc_init().

Parameters

dev	- The device structure.

Returns

0 in case of success, negative error code otherwise.

pulsar_adc_spi_reg_read()

int32_t pulsar_adc_spi_reg_read	(	struct pulsar_adc_dev *	dev,
		uint8_t *	reg_data )

Read from device.

Parameters

dev	- The device structure.
reg_data	- The register data.

Returns

0 in case of success, negative error code otherwise.

pulsar_adc_spi_reg_write()

int32_t pulsar_adc_spi_reg_write	(	struct pulsar_adc_dev *	dev,
		uint8_t	reg_data )

Write to device.

Parameters

dev	- The device structure.
reg_data	- The register data.

Returns

0 in case of success, negative error code otherwise.
