|
|
The KPP is designed to interface with a keypad matrix with 2-point contact
|
||
|
|
or 3-point contact keys. The KPP is designed to simplify the software task
|
||
|
|
of scanning a keypad matrix. The KPP is capable of detecting, debouncing,
|
||
|
|
and decoding one or multiple keys pressed simultaneously on a keypad.
