SeqButton

Sequential Button Arduino Library

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

Usage

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
