EdgePi ADC Node

EdgePi ADC node that reads voltage, differential, and RTD.

Details

Differential Types:

  • DIFF1: Ports 16 & 17
  • DIFF1: Ports 19 & 20
  • DIFF1: Ports 21 & 22
  • DIFF1: Ports 24 & 25

Assigned ports for RTD measurements:

  • 21
  • 24
  • 25

NOTE: Port 22 will also be disabled.

Properties

  • RPC Server:
    The connection to your EdgePi's RPC Server.
  • Reading:
    The type of reading you want the ADC to do next.
  • ADC:
    Which ADC you want to use for the next reading.
  • ADC Channel (when configured to read voltage):
    Which analog channel you read from next.
  • Data Rate (when configured to read voltage):
    The selected ADC's data rate. Note that data rates are different depending on which ADC you chose.
  • Differential (when configured to read differential):
    The differential you want to read next.

Inputs

  • payload (number)
    The input selection -- the channel number (1 to 8) or differential channels number (1 to 4) depending on the read type. Ignored for read type rtd.
  • readType (string)
    single, diff, or rtd. Default is single.
  • dataRate (number)
    ADC data rate. Valid values for ADC 1: [2.5, 5, 10, 16.6, 20, 50, 60, 100, 400, 1200, 2400, 4800, 7200, 14400, 19200, 38400] . Default is 38400. Valid values for ADC 2: [10, 100, 400, 800] . Default is 800.
  • adc (number)
    ADC number to use for reads. Valid values are 1 and 2. Forced to 2 when RTD readType is rtd. Default is 1.

Outputs

  • Read type single:
    • payload (number)
      Voltage reading of the specified single-ended analog input channel.
  • Read type diff:
    • payload (number)
      Differential voltage reading of the specified differential channels.
  • Read type rtd:
    • payload (number)
      RTD temperature reading in Celsius.
