Detailed Description

Function Documentation

dac2_cfg_setup()

void dac2_cfg_setup

(

dac2_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.

(

dac2_t *

ctx

)

Asynchronous Clear Input function.

Parameters

ctx	Click object.

@description This function clears all registers and causes the DAC voltage outputs to drop to 0V for LTC2601.

rd_buf	Read data buffer
rd_len	Number of byte in read data buffer

@description Generic SPI transfer, for sending and receiving packages

dac2_init()

DAC2_RETVAL dac2_init	(	dac2_t *	ctx,
		dac2_cfg_t *	cfg )

Initialization function.

Parameters

dac2	Click object.
cfg	Click configuration structure.

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

dac2_write_output_voltage_data()
