This library uniformly encapsulates the use of different types of switches for user input devices. The library is easily extended for additional switch types through a class hierarchy and inheritance model, following the code for existing switch types.
The library includes the following features:
- Software debounce for all switch types.
- Automatically detect switch press, double press, long press and auto repeat.
- Can work with low/high or high/low transitions.
- Timers are all software configurable - debounce time, double press time, long press time, and auto repeat period time.
Switch arrangements handled by the library are:
- Momentary on type switches (MD_Switch_Digital class)
- Analog resistor ladder switches (MD_Switch_Analog class)
- Keypad matrix (MD_Switch_Matrix class)
- Keypad matrix using 4017 IC (MD_Matrix_4017KM class)
