Pin Nodes

These nodes can be used to configure and use the GPIO pins of your microcontroller.

Config Nodes​

set get pin config​

To set get pin drive capability config.

Inputs

  • Pin number : Specify the pin number to configure drive capability
  • Drive capability : Select the drive capability for the pin

Proc Nodes​

write​

Writes the digital value 1 (3.3V) or 0 (0V) on the specified pin.

Inputs

  • Pin no. : Specify the pin to write to
  • Pin level : Set the logic level to be written to the pin

read​

Reads digital value 1 (3.3V) or 0 (0V) on the specified pin and outputs the value to the next nodes.

Inputs

  • Pin no. : Specific the pin number to read digital value from
  • Mode : Select a mode for reading

Outputs

  • pin level : logic level received at the pin

set pin direction​

Set the directions of GPIO pins to input or output and then use special write or read

Inputs

  • Read/Write : Select the IO direction for a pin
  • Pin no. : Specify a pin number to set the direction for
  • Mode : Select a mode for setting default logic level

special write​

Before using this you have to use set direction node .Writes the digital value 1 (3.3V) or 0 (0V) on the specified pin.

Inputs

  • Pin no. : Specify a pin number to write to
  • Pin level : Set the logic level for the pin

special read​

Before using this you have to use set direction node .Reads digital value 1 (3.3V) or 0 (0V) on the specified pin and outputs the value to the next nodes.

Inputs

  • Pin no. : Specify the pin number to read from

Outputs

  • pin level : logic level read at the pin

reset pin​

To reset the pin number.

Inputs

  • Pin number : Specify a pin number to reset to default state

change pullup pulldown status​

To change pullup pulldown status.

Inputs

  • Pin number : Specify the pin number to change the pull up/down status of
  • Pull select : Select the pull up/down status for the pin

change interrupt hold sleep status​

To change interrupt hold sleep status.

Inputs

  • Pin number : Specify the pin number to change the interrupt hold sleep status of
  • In select : Select a status for the pin

set drive capability​

To set drive capability.

Inputs

  • Set get setting. : Configure the settings to set the drive capability of a pin

get drive capability​

To get drive capability.

Inputs

  • Set get setting. : Select the configuration to retrieve the drive capability of a pin

Outputs

  • capability : drive capability of the pin

change wakeup status​

To change wakeup status.

Inputs

  • Pin number : Specify the pin to change the wakeup status of
  • Intr type : Select the interrupt type of wake up for a pin
  • Select : Select the wakeup status for the pin

Event Nodes​

on signal​

Sends out an event, to the next nodes when it receives a rising/falling voltage edge signal on the specified pin. The node outputs the latest digital value of the pin as 1 (3.3V) or 0 (0V)

Inputs

  • Pin no. : Specify the pin number to listen for signal
  • Edge type : Select the type of signal (edge type)
  • Enable pullup : Enable Pulluo for the pin
  • Enable pulldown : Enable Pulldown for the pin

Outputs

  • pin level : logic level received at the pin

on button click​

Sends out an event, to the next nodes when the button on the specified pin clicked.

Inputs

  • Pin no. : Specify the pin number to listen for the button click
  • Button pin is : Select the connection type
  • Auto pull-up/down enable : Enable auto pull-up/down
