DAC2 Unit
The Dac2 class interfaces with a GP8413 15-bit Digital to Analog Converter (DAC), capable of converting digital signals into two channels of analog voltage output, ranging from 0-5V and 0-10V.
Support the following products:
Micropython Example:
import os, sys, io
import M5
from M5 import *
import time
from unit import DAC2Unit
i2c = I2C(0, scl=Pin(1), sda=Pin(2), freq=400000)
dac2_0 = DAC2Unit(i2c0, 0x59)
dac2_0.setDACOutputVoltageRange(dac2_0.RANGE_10V)
dac2_0.setVoltage(7.5, channel=dac2_0.CHANNEL_BOTH)
UIFLOW2 Example:
class DAC2Unit
Constructors
- class DAC2Unit(i2c0, addr)
Create an DAC2Unit object.
I2C0
is I2C Port.addr
I2C address of the DAC (default is 0x59)..

Methods
- DAC2Unit.setDACOutputVoltageRange(_range)
Sets the output voltage range of the DAC.
_range
The DAC output voltage range, either DAC2Unit.RANGE_5V or DAC2Unit.RANGE_10V..
UIFLOW2:
- DAC2Unit.setVoltage(voltage, channel=Dac2.CHANNEL_BOTH)
Sets the output voltage of the DAC.
voltage
Desired output voltage from 0.0 to range maximum (5V or 10V).channel
The DAC channel to set. Options are Dac2.CHANNEL_0, Dac2.CHANNEL_1, or Dac2.CHANNEL_BOTH.
UIFLOW2:
- DAC2Unit.setVoltageBoth(voltage0, voltage1)
Sets the output voltage for both channels.
voltage0
Desired output voltage from 0.0 to range maximum (5V or 10V).voltage1
Desired output voltage from 0.0 to range maximum (5V or 10V).
