Detail

Node in-gpio reads single gpio input.

• Watch rising and/or falling edge of gpio input.
• On any gpio input changes, a message is send to node output.
• Gpio input can be set as floating, pullup and pulldown resistor.
• A debounce time can be set for gpio input.

Node out-gpio sets single gpio output.

• Input message sets gpio output.
• Output can be set to source, sink or both driven mode.
• Mode toggle changes output on any node input message.
• Mode blink blinks on input message period time.

Node pwm-gpio generates pulse wide modulation on gpio output.

• PWM frequency can be from 1Hz up to 45000Hz.
• Duty cycle are from 0% to 100%.
• Duty cycle 0% turns output off, 100% turns output on.
• PWM pulse is software generated.
• For better accuracy PWM realtime mode can be set.
  
• With input messages, frequency and duty cycle can be changed.
• With input messages, output can be turn on/off.

Node gpio-cnt high speed up/down gpio input counter.

• Counts on rising and/or falling edge of gpio input.
• Counter input can be set as floating, pullup and pulldown resistor.
• A debounce time can be set for gpio counter input.
• Counter can be reset with rising and/or falling edge of gpio input.
• Reset input can be set as floating, pullup and pulldown resistor.
• A debounce time can be set for gpio counter reset input.
• When the counter reaches limits, a gpio output is set.
• Resetting and setting the limit of counter can also be done via node input.
• On any counter changes, a message is send to node outputs.

This node works on Raspberry Pi with 32bit or 64bit OS.
Works also on Raspberry Pi 5.
