- Configuration
- -------------
- #define SAMPLE_COUNT in this header file.
- define and initilize DELAY_MICROSECONDS in sketch.
- const unsigned int Row::DELAY_MICROSECONDS = 0;
-
- Instantiation
- ------------
- Example instantiation of a row:
- RowPort_AVR rowPortF(DDRF, PORTF);
-
- ColPort_AVR colPortB(DDRB, PORTB, PINB, 1<<0 | 1<<1 | 1<<2 | 1<<3 );
- ColPort_AVR colPortD(DDRD, PORTD, PIND, 1<<2 | 1<<3 );
-
- ColPort* const ptrsColPorts[] = { &colPortB, &colPortD };
- const uint8_t COL_PORTS_COUNT = sizeof(ptrsColPorts)/sizeof(*ptrsColPorts);
-
- const PROGMEM Key* const ptrsKeys_0[] = { &k_00, &k_01, &k_02, &k_03, &k_04, &k_05 };
- Row row_0(ptrsKeys_0, &rowPortF, 1<<0, ptrsColPorts, COL_PORTS_COUNT);
-
- Number of ColPort::colPins should equal number of keys in Row::ptrsKeys 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
