Node-Red node for EdgePi PWM

Configures a PWM port on the EdgePi.

Properties

• RPC Server: The connection to your EdgePi's RPC Server.
• PWM: The PWM Pin to configure on the EdgePi.
• State: Whether the PWM Pin is enabled or disabled.
• Polarity: Determines the signal's resting state (high or low).
• Frequency: Rate at which the PWM completes a cycle.
• Duty Cycle: Percentage of one cycle in which a signal is active.

Inputs

• msg.payload number: The duty cycle.
• msg.frequency number
• msg.polarity string
• msg.enabled boolean

Example input configuration:

msg {
  "payload": 0,
  "frequency": 1000,
  "polarity": "NORMAL",
  "enabled": false
}

Outputs

Values of successfully configured properties.

• msg.payload number: Either the duty cycle or an error message in an error case.
• msg.pwmPin string
• msg.frequency number
• msg.polarity string
• msg.enabled boolean

Example output:

msg {
  "payload": 0,
  "pwmPin": "PWM1",
  "frequency": 1000,
  "polarity": "NORMAL",
  "enabled": false
}
