XBee®/XBee‐PRO® RF Modules ‐ 802.15.4 ‐ v1.xEx [2009.09.23]
IO (Digital Output Level) Command
IR (Sample Rate) Command
IS (Force Sample) Command
IT (Samples before TX) Command
<I/O Settings> The IO command is used to set
digital output levels. This allows DIO lines setup
as outputs to be changed through Command
Mode.
<I/O Settings> The IR command is used to set/
read the sample rate. When set, the module will
sample all enabled DIO/ADC lines at a specified
interval. This command allows periodic reads of
the ADC and DIO lines in a non-Sleep Mode
setup. A sample rate which requires transmis-
sions at a rate greater than once every 20ms is
not recommended.
Example: When IR = 0x14, the sample rate is 20 ms (or 50 Hz).
<I/O Settings> The IS command is used to force
a read of all enabled DIO/ADC lines. The data is
returned through the UART.
When operating in Transparent Mode (AP=0), the
data is retuned in the following format:
All bytes are converted to ASCII:
When operating in API mode (AP > 0), the command will immediately return an ‘OK’ response.
The data will follow in the normal API format for DIO data.
<I/O Settings> The IT command is used to set/
read the number of DIO and ADC samples to col-
lect before transmitting data.
One ADC sample is considered complete when all
enabled ADC channels have been read. The mod-
ule can buffer up to 93 Bytes of sample data.
Since the module uses a 10-bit A/D converter, each sample uses two Bytes. This leads to a maxi-
mum buffer size of 46 samples or IT=0x2E.
When Sleep Modes are enabled and IR (Sample Rate) is set, the module will remain awake until IT
samples have been collected.
