- Instantiation
- -------------
- Definition of DELAY_MICROSECONDS is explained in RowBase.cpp.
- Example instantiation of a row:
-
- const unsigned int RowBase::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
