Dynamic C LIB\KEYPADS library folder.
Initializes keypad process
RETURN VALUE
None.
SEE ALSO
brdInit
Assigns each key with key press and release codes, and hold and repeat ticks for auto repeat and
debouncing.
PARAMETERS
cRaw
is a raw key code index.
1 × 7 keypad matrix with raw key code index assignments (in brackets):
User Keypad Interface
cPress
is a key press code
An 8-bit value is returned when a key is pressed.
0 = Unused.
See keypadDef() for default press codes.
cRelease
is a key release code.
An 8-bit value is returned when a key is pressed.
0 = Unused.
cCntHold
is a hold tick, which is approximately one debounce period or 5 s.
How long to hold before repeating.
0 = No Repeat.
cSpdLo
is a low-speed repeat tick, which is approximately one debounce period or 5 s.
How many times to repeat.
0 = None.
cCntLo
is a low-speed hold tick, which is approximately one debounce period or 5 s.
How long to hold before going to high-speed repeat.
0 = Slow Only.
