High Precision Data Acquisition Shield Library

Usage:

#include <HPDAQ.h>

HPDAQ daq(0);

You can specify the board address 0-7 in the constructor. Current shields only support address 0.

Read a raw sample:

int val = daq.analogRead(channel);
// channel = 0 to 3

Read a voltage:

double volts = daq.analogReadVoltage(channel);

Select the resolution:

daq.setResolution(HPDAQ::RES_12);
daq.setResolution(HPDAQ::RES_14);
daq.setResolution(HPDAQ::RES_16);

Select the pre-amp gain:

daq.setGain(HPDAQ::GAIN_1);
daq.setGain(HPDAQ::GAIN_2);
daq.setGain(HPDAQ::GAIN_4);
daq.setGain(HPDAQ::GAIN_8);

Start a background sample:

daq.startConversion(channel);

Retrieve the results of the last background conversion:

int val = daq.fetchResult();
double volts = daq.fetchResultVoltage();
// These functions block until the conversion is complete if
// not already complete.
