Function Documentation

void tlv5618_init	(	Tlv5618 *	ctx,
		KFile *	ch,
		int	cs_pin
	)

Init the TLV5618 with CS connected to cs_pin.

ch should be the SPI channel needed to communicate with the DAC. This SPI should also be correctly configured (the MOSI should change on the rising edge of the SCK clock).

Note:

the device is set in power down mode.

void tlv5618_setOutA	(	Tlv5618 *	ctx,
		uint16_t	val
	)

Set DAC output A to val.

val ranges from 0 to 4095 (12 bit).

Note:

: if in power down, the device will be awaken.

void tlv5618_setOutB	(	Tlv5618 *	ctx,
		uint16_t	val
	)

Set DAC output B to val.

val ranges from 0 to 4095 (12 bit).

Note:

: if in power down, the device will be awaken.
