/* Row_uC is a row connected to a micro controller.
Configuration
-------------
Define and initilize DELAY_MICROSECONDS in sketch.  Detailed how to is in RowBase.cpp.

Instantiation
-------------
Example instantiation of a row:

    const uint8_t colPins[] = {0,1,2,3,7,8};
    const uint8_t COL_PIN_COUNT = sizeof(colPins)/sizeof(*colPins);

    Key* const ptrsKeys_0[] = { &k_00, &k_01, &k_02, &k_03, &k_04, &k_05 };
    Row_DH_uC row_0(21, colPins, COL_PIN_COUNT, ptrsKeys_0);

Number of colPins should equal number of keys in ptrsKeys_0[] array.
    if a colPin is missing, a key will be unresposive
    if a Key pointer is missing, the keyboard will fail in an unprdictable way
