SWITCHES
The BIGAVR2 development board features a number of peripheral devices. In order to enable
them before programming, the appropriate jumpers or switches have to be properly set.
Switches are mechanical devices which have two positions - ON and OFF. Their function is
to establish or break connection between two contacts. The BIGAVR2 development board has
four groups of switches.
Switch group SW1 is used to enable/disable LEDs connected to the microcontroller ports.
Five out of eleven ports have its own switch, while the ports F, G, H, J, K and C share three
lower switches of this group.
Switch group SW2 is used to enable/disable touch panel and MMC card reader.
Switch group SW3 is used to enable/disable RS232 communication.
Switch group SW4 is used to enable/disable external pull-up/pull-down resistors on PORTF
pins. Each pull-up/pull-down resistor is individually enabled.
