Function Documentation

adt7420_get_register_address_and_value()

int32_t adt7420_get_register_address_and_value	(	struct adt7420_dev *	dev,
		uint16_t	register_address,
		uint16_t *	reg_val
	)

Reads the value of a register SPI/I2C.

Parameters

dev	- The device structure.
register_address	- Address of the register.
reg_val	- Value of the concerned register

Returns

0 in case of success, negative error code otherwise

adt7420_set_ct_int_mode()

int32_t adt7420_set_ct_int_mode	(	struct adt7420_dev *	dev,
		uint8_t	setting
	)

Sets comparator/interrupt (CT/INT) mode for ADT7420/ADT7320.

Parameters

dev	- The device structure.
setting	- Mode selection. Example: 0 - Interrupt (default). 1 - Comparator.

Returns

0 in case of success, negative error code otherwise.

	)

Write to a setpoint register.

Parameters

dev	- The device structure.
register_value	- Command control bits.
data	- Data to be written in input register.

Returns

0 in case of success, negative error code otherwise

configure_write_type_registers()

uint16_t configure_write_type_registers	(	struct adt7420_dev *	dev,
		uint16_t	register_address
