If this value is true, the output value will also be written to the MCP4725's internal non-volatile memory, meaning that the DAC will retain the current voltage output after power-down or reset.
VALnumber
The value from 0.0 to 1.0 representing the relationship between the DAC's input voltage and its output voltage.
To use the node in your project you should have the e/mcp4725 library installed. Use the “File → Add Library” menu item in XOD IDE if you don’t have it yet. See Using libraries for more info.
