SWITCHES
The dsPICPRO 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.
The first switch,
SW1,
is used to enable LEDs connected to ports RB_L, RB_H,
RD_L, RD_H, RF and RG. For example, if switch RB_L is OFF, all RB lower
LED’s will be turned off.
The switches
SW2
and
SW3
are used to enable connections between various
peripheral devices and microcontroller pins.
For example,
SW2
and
SW3
, enables a connection between the microcontroller
pins and temperature sensor, programmable gain amplifier (PGA), real time clock
(RTC), RS-485 communication etc.
