LED (Light-Emitting Diode) is a highly effi cient electronic light source. When connecting LEDs, it is necessary to use a current limiting
resistor. A common LED diode voltage is approximately 2.5V, while the current varies from 1 to 20mA depending on the type of LED.
The LV 18F v6 uses LEDs with current I=1mA.
There are 70 LEDs provided on the LV 18F v6 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, PORTH or PORTJ) using DIP switch SW10.
