LEDs

Light Emitting Diodes (LEDs) are components most commonly used for displaying pins’ dig-
ital state. BIGAVR2 has 86 LEDs connected to the microcontroller ports: PORTA, PORTB,
PORTC, PORTD, PORTE, PORTF, PORTG, PORTH, PORTJ, PORTK and PORTL.

On-board LEDs
The development system is capable of monitoring the state of eleven MCU ports. Each of
these ports is connected to eight LEDs which can be enabled or disabled using switches of the
switch group SW1. The only exception is port PORG connected to six LEDs.
LEDs are enabled when the corresponding switch of the SW1 is ON. When enabled, LEDs
display the state of the corresponding microcontroller pin. Otherwise, the LEDs are always
off, no matter what the port state is, as no current can flow through them.
