Digi XBee3 802.15.4 User Manual

I/O support I/O sample data format
Digi XBee3® 802.15.4 RF Module User Guide
46
Bytes Name Description
1 Sample
sets
Number of sample sets. This is determined by IT (Samples before TX) on the
source node.
2 Digital
and
analog
channel
mask
Indicates which digital I/Oand ADC lines have sampling enabled. Each bit
corresponds to one digital I/O or ADC line on the device.
bit 0 = DIO0
bit 1 = DIO1
bit 2 = DIO2
bit 3 = DIO3
bit 4 = DIO4
bit 5 = DIO5
bit 6 = DIO6
bit 7 = DIO7
bit 8 = DIO8
bit 9 = ADC0
bit 10 = ADC1
bit 11 = ADC2
bit 12 = ADC3
bit 13 = Reserved
bit 14 = Reserved
bit 15 = Reserved
Example: a channel mask of 0x063C means ADC0, ADC1, DIO2, DIO3, and DIO5
are configured as digital inputs or outputs.
2 Digital
data set
Each bit in the digital data set corresponds to a digital bit in the channel mask
and indicates the state of the digital pin, whether high (1) or low (0).
If the digital portion of the channel mask is 0, then these two bytes are omitted
as no digital I/O lines are enabled.
bit 0 = DIO0
bit 1 = DIO1
bit 2 = DIO2
bit 3 = DIO3
bit 4 = DIO4
bit 5 = DIO5
bit 6 = DIO6
bit 7 = DIO7
bit 8 = DIO8
bit 9 = N/A
bit 10 = N/A
bit 11 = N/A
bit 12 = N/A
bit 13 = N/A
bit 14 = N/A
bit 15 = N/A
2 Analog
data set
(multiple)
Each enabled ADC line in the analog portion of the channel mask has a separate
2-byte value based on the number of ADC inputs on the originating device. The
data starts with AD0 and continues sequentially for each enabled analog input
channel up to AD3.
If the analog portion of the channel mask is 0, then no analog sample bytes are
included.
