Detailed Description

Function Documentation

dac6_cfg_setup()

void dac6_cfg_setup

(

dac6_cfg_t *

cfg

)

Config Object Initialization function.

Parameters

cfg	Click configuration structure.

@description This function initializes click configuration structure to init state.

Note

All used pins will be set to unconnected state.

dac6_generic_transfer()

void dac6_generic_transfer	(	dac6_t *	ctx,
		uint8_t *	wr_buf,
		uint16_t	wr_len,
		uint8_t *	rd_buf,
		uint16_t	rd_len )

Generic transfer function.

Parameters

ctx	Click object.
wr_buf	Write data buffer
wr_len	Number of byte in write data buffer
rd_buf	Read data buffer
rd_len	Number of byte in read data buffer

@description Generic SPI transfer, for sending and receiving packages

dac6_init()

DAC6_RETVAL dac6_init	(	dac6_t *	ctx,
		dac6_cfg_t *	cfg )

Initialization function.

Parameters

ctx	Click object.
cfg	Click configuration structure.

@description This function initializes all necessary pins and peripherals used for this click.

dac6_set_output()

float dac6_set_output

(

dac6_t *

ctx

)

Set DAC output function.

Parameters

ctx	Click object. Strucrure arguments: - chan 8-bit data that defines output channel - op_mod 8-bit data that defines mode of operation - set_out 16-bit data that defines output level - v_ref 16-bit reference voltage input [ mv ]

@description Function is used to set operation mode output channel and level.

Note

- Device's output levels range from 0 to 4095.
- Device's ideal output voltage can be calculated by using 
      the equation :  Vout = Vrefin � (set_out / 4095).
- It is advisable to use predefined values or to consult the datasheet.

dac6_write_data()

void dac6_write_data	(	dac6_t *	ctx,
		uint16_t	wr_data )

Generic write function.

Parameters

ctx	Click object.
wr_data	16-bit write data

@description Sends 16-bit data to the device's input shift register.
