- /* Row_DH_IOE is a row connected to an Input/Output Expander.
-
- Instantiation
- -------------
- Definition of DELAY_MICROSECONDS is explained in RowBase.cpp.
- Definition of activeHigh is explained in RowScanner_Interface.h
- Example instantiation of a row:
-
- const unsigned int RowBase::DELAY_MICROSECONDS = 1000;
- const bool RowScanner_PinsArray::activeHigh = 0;
-
- const uint8_t IOExpanderPort::ADDR = 0x18;
-
- IOExpanderPort port1(1, 0);
- RowPort_PCA9655E rowPort1(port1);
-
- IOExpanderPort port0(0, 0);
- ColPort_PCA9655E colPort0(port0, 1<<0 | 1<<1 | 1<<2 | 1<<3 | 1<<4 | 1<<5 );
-
- Key* const ptrsKeys_0[] = { &k_00, &k_01, &k_02, &k_03, &k_04, &k_05 };
- Row_IOE row_0(rowPort1, 1<<0, colPort0, 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
