Function Documentation

ltc2312_code_to_voltage()

void ltc2312_code_to_voltage	(	struct ltc2312_dev *	dev,
		uint16_t	adc_code,
		float	vref,
		float *	voltage )

Calculates the LTC2312 input voltage given the binary data and LSB weight.

Parameters

[in]	dev	- The device structure.
[in]	adc_code	- Raw ADC code.
[in]	vref	- The reference voltage of the ADC.
[out]	voltage	- Voltage value calculated.

ltc2312_read()

int32_t ltc2312_read	(	struct ltc2312_dev *	dev,
		uint16_t *	ptr_adc_code )

Reads the LTC2312 and returns 16-bit data in offset binary format.

Parameters

[in]	dev	- The device structure.
[out]	ptr_adc_code	- Read data.

Returns

0 for success, or negative error code otherwise.

ltc2312_remove()

int32_t ltc2312_remove

(

struct ltc2312_dev *

dev

)

Free the resources allocated by ltc2312_setup().

Parameters

[in]

dev

- The device structure.

Returns

0 in case of success, negative error code otherwise.

ltc2312_setup()

int32_t ltc2312_setup	(	struct ltc2312_dev **	device,
		struct ltc2312_init_param *	init_param )

Initializes the ltc2312 device handler.

Parameters

[out]	device	- The device structure.
[in]	init_param	- The structure that contains the device initial parameters.

Returns

0 for success, or negative error code otherwise.
