#include <Max1148.hpp>

Public Member Functions
	Max1148 (Channel channel)
	ADC constructor. Sets cs_pin as per ADC_CS_PIN macro. Chooses channel from Channel enum.

Private Member Functions
void	csl ()
	Sets the chip select pin to low.
void	csh ()
	Sets the chip select pin to high.
uint16_t	adc_read_avg (int avg_number)
	Reads an average ADC value from the Max1148 ADC. Uses Arduino's SPI library. We don't use this anymore because we wanted to interleave ADC sampling between channels.
uint16_t	adc_read ()
	Reads a single ADC value from the Max1148 ADC. Used in adc_read_avg.

Private Attributes
int	cs_pin
	Chip select pin for the ADC.
uint8_t	channel
	Channel for the ADC. Selected in the constructor.

Friends
class	Pip
	ADC functions should really only be used in relation to Pip measurements, so everything is private and Pip is a friend.

Constructor & Destructor Documentation

Max1148()

Max1148::Max1148 ( Channel  channel )

inline

ADC constructor. Sets cs_pin as per ADC_CS_PIN macro. Chooses channel from Channel enum.

Parameters

channel

The channel to read from. Format: CHAN0, CHAN1, etc. I don't remember why it has to be static_cast but it works.
