4.4.4 Keypad Controls
Scans and processes keypad data (up to 8 × 8 matrix) for key assignment, debouncing, press and release,
and repeat. Provides debouncing, user-definable key code, separate press and release code (both
optional), two- and three-speed auto repeat.
RETURN VALUE
None.
SEE ALSO
keyConfig, keyGet, keypadDef
Assigns user-defined keys to keypad positions. Defines ticks for key debouncing and speed.
PARAMETERS
cRaw is the Raw Key Code Index, a 2 × 6 keypad matrix with the following raw keycode index assign-
ments.
cPress is the Key Press Code, an 8-bit value returned when a key is pressed (0 = Unused). See
keypadDef for default press codes.
cRelease is the Key Release Code, an 8-bit value to be returned when a key is released (0 = Unused).
cCntHold is Hold Ticks, how long to hold before repeating (0 = No Repeat).
cSpdLo is Low-Speed Repeat Ticks, how many times to repeat (0 = None).
cCntLo is Low-Speed Hold Ticks, how long to hold before going to high-speed repeat (0 = Slow
Only).
cSpdHi is High-Speed Repeat Ticks, how many times to repeat after low-speed repeat (0 = None).
RETURN VALUE
None.
