LTC2309_read()

int8_t LTC2309_read	(	uint8_t	i2c_address,
		uint8_t	adc_command,
		uint16_t *	ptr_adc_code
	)

Reads 12-bit code from LTC2309, programs channel and mode for next conversion.

Returns

Returns the state of the acknowledge bit after the I2C address write. 0=acknowledge, 1=no acknowledge.

Parameters

i2c_address	I2C address of device
adc_command	ADC command / address bits
ptr_adc_code	Returns code read from ADC
