XBee Shield, Руководство по подключению

Страница: 9 / 24

The switch configuration from the XBee Shield schematic . "D_TX" connects to Arduino pin 3, and
"D_RX" connects to Arduino pin 2.
For all of our example sketches we'll assume the switch is in the DLINE position . At the very least,
make sure the switch is in the "DLINE" position when uploading sketches
.
Status LED Indicators
There are 5 LEDs on the XBee Shield. Each of these LEDs connects to a pin on the XBee, which
does most of the LED driving. Here's a table explaining the operation of each LED:

Default Operation Notes
PWR
Red 3.3V Indicates power is present.
DIO5
Green Associate/DIO5
Associated indicator -- blinks when the XBee is associated
with another XBee.
DOUT Red DOUT Indicates wireless data is being received.
DIN Green DIN Indicates wireless data is being transmitted.
RSSI
Green PWM0/RSSI
Indicates relative signal strength (RSSI) of last received
transmission.
These LEDs can be very useful for debugging. The DIO5/Associate indicator should blink when the
XBee is paired with a compatible device. The RSSI LED is actually PWM'd so it will be brighter
