SWITCHES
dsPICPRO3 development board features many peripherial devices. In order to enable these
devices before programming, you need to check if appropriate jumpers or switches have
been properly set.
Switches are devices that have two positions - ON and OFF- which have a role to establish
or break a connection between two contacts. dsPICPRO3 development system has four
groups of switches.
.
The first group,
SW1,
is used to enable LEDs connected to PORTA, PORTB low, PORTB
high, PORTC, PORTD low, PORTD high, PORTF, PORTG low and PORTG high. For
example, if switch 1 on
SW1
is OFF then all PORTA LEDs will be turned off.
Switch 1 on
SW2
turns LEDs on PORTG high ON or OFF. Switches 2 and 3 are used to
enable LCD and GLCD backlight, switch 4 to enable Digital Thermometar and switch 5 to
enable Real Time Clock Interrupt line. Switch 6 is used to enable MMC Chip Select line
and the last two switches on SW2 are used to enable Serial Ethernet.
The first two switches on
SW3
are used to enable Serial Ethernet. Switches 3, 4, 5 and 6
are used to enable CAN Communication and the last two switches are used to enable D\A
Converter.
Switches 1, 2 and 3 on
SW4
are used to enable RS485 Communication. Switches 4, 5 and
6 are used to enable SPI Communication and the last two switches are used to enable Real
Time Clock.
