Detailed Description

MCP4725 digital DAC driver.

Function Documentation

bool mcp4725_is_busy

(

void

)

Function for checking if DAC is busy saving data in EEPROM.

Return values

true	If DAC is busy.
false	If Dac is not busy.

ret_code_t mcp4725_set_voltage	(	uint16_t	val,
		bool	write_eeprom
	)

Function for setting new value to DAC.

Parameters

[in]	val	12-bit value. Base on it voltage is set (Vout = (val/4095) * Vcc).
[in]	write_eeprom	Defines if value will be written to DAC only or to EEPROM memmory also.

Returns

Values returned by nrf_drv_twi_tx.

ret_code_t mcp4725_setup

(

mcp4725_pins_config_t const *

p_pins_config

)

Function for setting up the driver.

Parameters

[in]

p_pins_config

Pointer to structere holding pins numbers to be used by TWI.

Returns

Values returned by nrf_drv_twi_init.
