Sequential Button Arduino Library

Handling filtered button press with callbacks for push (with or without repeat) and release, logic, filtering time and sequences.

• Declare a SeqButton instance (called sb below)
• Create callback function(s) of type void func()
• Initialize instance with sb.init(uint8_t pin, void (*cbckON)(SeqButton*), void (*cbckOFF)(SeqButton*), bool repeat, bool logic=LOW, uint16_t filter=50)
  • pin: pin on which button is connected
  • cbckON: callback function on press (NULL when no callback needed)
  • cbckOFF: callback function on release (NULL when no callback needed)
  • repeat: callback called repeatedly when set to true
  • logic: Button logic: LOW for NO / HIGH for NC (internal pullup for input is enabled)
  • filter: filtering time (in ms)
• Call the handler in a loop using sb.handler() -> handler returns the current button value (if needed)
• sb.getState() or sb.getButton() can be used to get current button state at any time
• sb.getPin() can be used to check pin assigned to instance
• sb.getHoldTime() can be used on a release callback to get hold duration of button

• AdvancedButton.ino: Toggle a LED at each button press (showing all init parameters)
• CallbacksExample.ino: Toggle a LED at each push on button 1 and at each release on button 2
• CombinationExample.ino: Prints messages to serial depending on combination read from inputs
• OffTimerButton.ino: Turns a LED on when button is pressed, turning off 1s after release
• RepeatButton.ino: Toggle a LED repeatedly when button pressed
• SequenceExample.ino: Prints messages to serial depending on sequence read from inputs
• TimingExample.ino: Toggle a LED at each push on button 1 or 2 if held for more than 1s
• ToggleButton.ino: Toggle a LED at each button press
