EdgePi DAC node

EdgePi DAC node that reads/writes voltage to a given output channel.

Install

Install normally through the node-red editor or install with npm in your node-red directory (typically located at ~/node.red) by running the following command:

Properties

  • RPC Server
    The connection to your EdgePi's RPC Server.
  • Channel

  • Gain
    Enable/ disable internal DAC gain. Gain enabled allows for a larger output voltage for a given input voltage but reduces accuracy.

    The amount of voltage to write to a selected channel. Range is 0-5 for gain off and 0-10 for gain on.

Inputs

  • payload number:
    The voltage to write.
  • gain boolean:
    'false' for gain disabled (off), 'true' for gain enabled (on).
  • channel number:

Example input:

msg {
  "payload": 2.5,
  "gain": false,
  "channel": 7
}

Outputs
