Pointer to the keypad to configure.
Raw Key Code Index Each key has a raw key code. The raw key codes start
from 0 and count up. Each crosswired keypad has m outputs and n inputs,
which may or may not correspond to rows and columns.
The raw key code can be calculated by the following formula.
where the output # and input # start from 0. If these correspond to rows and
columns, then the formula would be as follows.
Key Press Code An 8-bit value returned when a key is pressed;
0 = unused.
Key Release Code An 8-bit value returned when a key is released;
0 = unused.
Hold Ticks How long to hold before repeating;
0 = No Repeat.
Low-Speed Repeat Ticks How many times to repeat;
0 = none.
Low-Speed Hold Ticks How long to hold before going to high-speed repeat;
0 = slow only.
High-Speed Repeat Ticks How many times to repeat after low-speed repeat;
0 = none.
[output #] * [num outputs] + [input #]
[row #] * [num rows] + [column #]
