/* Row_DH_IOE is a row connected to an Input/Output Expander.

|
|
Instantiation
|
|
-------------
|
|
Definition of DELAY_MICROSECONDS is explained in Row.cpp.
|
|
Example instantiation of a row:
|
|
|
|
const unsigned int Row::DELAY_MICROSECONDS = 1000;
|
|
|
|
todo
|
|
|
|
Key* const ptrsKeys_0[] = { &k_00, &k_01, &k_02, &k_03, &k_04, &k_05 };
|
|
Row_ShiftRegisters row_0(uint8_t BYTE_COUNT, ptrsKeys_0);
|
|
|
|
Number of pins in colPort0 should equal number of keys in ptrsKeys_0[] array.
|
|
if a pin is missing, a key will be unresposive
|
|
if a Key pointer is missing, the keyboard will fail in an unprdictable way
