MCP4728

Arduino library for ]]>MCP4728]]> quad channel, 12-bit voltage output Digital-to-Analog Convertor with non-volatile memory and I2C compatible Serial Interface

This library is highly inspired from ]]>this great work]]>

Usage

#include <Wire.h>

include "MCP4728.h"

MCP4728 dac;

void setup() { Serial.begin(115200); // initialize serial interface for print()

Wire.begin(21, 22);
dac.attatch(Wire, 14);
dac.readRegisters();

dac.selectVref(MCP4728::VREF::VDD, MCP4728::VREF::VDD, MCP4728::VREF::INTERNAL_2_8V, MCP4728::VREF::INTERNAL_2_8V);
dac.selectPowerDown(MCP4728::PWR_DOWN::GND_100KOHM, MCP4728::PWR_DOWN::GND_100KOHM, MCP4728::PWR_DOWN::GND_500KOHM, MCP4728::PWR_DOWN::GND_500KOHM);
dac.selectGain(MCP4728::GAIN::X1, MCP4728::GAIN::X1, MCP4728::GAIN::X2, MCP4728::GAIN::X2);
dac.analogWrite(MCP4728::DAC_CH::A, 111);
dac.analogWrite(MCP4728::DAC_CH::B, 222);
dac.analogWrite(MCP4728::DAC_CH::C, 333);
dac.analogWrite(MCP4728::DAC_CH::D, 444);

dac.enable(true);

dac.readRegisters();
printStatus();
delay(5000);

}

void loop() { static int count = 0; if (++count > 4000) count = 0;

dac.analogWrite(count, count, count, count);

delay(10);
dac.readRegisters();
printStatus();

}

void printStatus() { Serial.println("NAME Vref Gain PowerDown DACData"); for (int i = 0; i < 4; ++i) { Serial.print("DAC"); Serial.print(i, DEC); Serial.print(" "); Serial.print(" "); Serial.print(dac.getVref(i), BIN); Serial.print(" "); Serial.print(dac.getGain(i), BIN); Serial.print(" "); Serial.print(dac.getPowerDown(i), BIN); Serial.print(" "); Serial.println(dac.getDACData(i), DEC);

    Serial.print("EEPROM");
    Serial.print(i, DEC);
    Serial.print("    ");
    Serial.print(dac.getVref(i, true), BIN);
    Serial.print("     ");
    Serial.print(dac.getGain(i, true), BIN);
    Serial.print("       ");
    Serial.print(dac.getPowerDown(i, true), BIN);
