The XBee®/XBee-PRO® RF Modules support ADC (Analog-to-digital conversion) and digital I/O
line passing. The following pins support multiple functions:
Table 2‐01. Pin functions and their associated pin numbers and commands
To enable ADC and DIO pin functions:
I/O data begins with a header. The first byte of the header defines the number of samples forth-
coming. The last 2 bytes of the header (Channel Indicator) define which inputs are active. Each
bit represents either a DIO line or ADC channel.
Figure 2‐04. Header
Sample data follows the header and the channel indicator frame is used to determine how to read
the sample data. If any of the DIO lines are enabled, the first 2 bytes are the DIO sample. The
ADC data follows. ADC channel data is represented as an unsigned 10-bit value right-justified on
a 16- bit boundary.
