               Adafruit MCP4725

Pi 5V Vin Pi Grnd GND Pi Pin5 SCL Pi Pin3 SDA Pi Grnd A0 MCP3008 ch7 Vout

  1. mvn clean package
  2. cd target/distribution
  3. sudo ./runMCP4725.sh parms........

-rde anf -rdf both have max input value 0x0FFF

-ef and -ev cannot exceed -vref

-vref option: the -d feature will display calculated output voltage.

Updates using raw binary value To Update DAC and EEPROM, set to 50 % of reference voltage Vin of 5 volts

sudo ./runMCP4725.sh -b 0x01 -a 0x62 -rde 0x7ff -vref 5.0

To Update DAC Fast, set to 50 % of reference voltage
sudo ./runMCP4725.sh -b 0x01 -a 0x62 -rdf 0x7ff -vref 5.0

To Update DAC Fast, set to 50 % of reference voltage Set trace level 'off' sudo ./runMCP4725.sh -b 0x01 -a 0x62 -rdf 0x07ff -t off -vref 5.0

To Update DAC Fast, set to 50 % of reference voltage, reset chip, dump DAC and EEPROM
sudo ./runMCP4725.sh -b 0x01 -a 0x62 -rdf 0x07ff -r -d -vref 5.0

Updates using voltage value

To Update DAC and EEPROM, set to 50 % of reference voltage Vin of 5 volts

sudo ./runMCP4725.sh -b 0x01 -a 0x62 -fv 2 -vref 5.0

To Update DAC Fast, set to 50 % of reference voltage
sudo ./runMCP4725.sh -b 0x01 -a 0x62 -fv 1.8 -vref 5.0

To Update DAC Fast, set to 50 % of reference voltage Set trace level 'off' sudo ./runMCP4725.sh -b 0x01 -a 0x62 -ev 5.0 -t off -vref 5.0

To Update DAC Fast, set to 50 % of reference voltage, reset chip, dump DAC and EEPROM
sudo ./runMCP4725.sh -b 0x01 -a 0x62 -ev 3.1 -r -d -vref 5.0
