8. XBee Analog and Digital IO Lines
XBee ZB firmware supports a number of analog and digital IO pins that are configured through software commands.
Analog and digital IO lines can be set or queried. The following table lists the configurable IO pins and the corresponding
configuration commands.
IO Configuration
IO Sampling
To enable an analog or digital IO function on one or more XBee module pin(s), the appropriate configuration
command must be issued with the correct parameter. After issuing the configuration command, changes must be
applied on the module for the IO settings to take effect.
Pull-up resistors can be set for each digital input line using the PR command. The PR value updates the state of all
pull-up resistors.
The XBee ZB modules have the ability to monitor and sample the analog and digital IO lines. IO samples can be read
locally or transmitted to a remote device to provide indication of the current IO line states. (Only API firmware
devices can send remote IO sample data out their UART.)
There are three ways to obtain IO samples, either locally or remotely:
