resistor. A common LED voltage is approximately 2.5V, while the current varies from 1 to 20mA depending on the type of LED. The
BIGdsPIC6
uses LEDs with current I=1mA.
There are 77 LEDs on the
BIGdsPIC6
development system which visually indicate the state of each microcontroller I/O pin. An
active LED indicates that a logic one (1) is present on the pin. In order to enable the pin state to be shown, it is necessary to select
appropriate port (PORTA, PORTB, PORTC, PORTD, PORTE, PORTF, PORTG or PORTG/E) using the DIP switch SW11.
