Enhanced data format
Ifyou set AOto 0 or 1 on both the source and destination node, then the data format is represented
as a series of bytes in the following format which matches the DigiMesh and Zigbee firmwares:
Bytes Name Description
1 Sample
sets
Number of sample sets. There is always one sample set per frame.
2 Digital
channel
mask
Indicates which digital I/O lines have sampling enabled. Each bit corresponds to
one digital I/O 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 = DIO9
bit 10 = DIO10
bit 11 = DIO11
bit 12 = DIO12
bit 13 = DIO13
bit 14 = DIO14
bit 15 = N/A
Example: a digital channel mask of 0x002F means DIO0, 1, 2, 3 and 5 are
configured as digital inputs or outputs.
1 Analog
channel
mask
Indicates which lines have analog inputs enabled for sampling. Each bit in the
analog channel mask corresponds to one analog input channel. If a bit is set,
then a corresponding 2-byte analog data set is included.
bit 0 = AD0/DIO0
bit 1 = AD1/DIO1
bit 2 = AD2/DIO2
bit 3 = AD3/DIO3
2 Digital
data set
Each bit in the digital data set corresponds to a bit in the digital channel mask
and indicates the digital state of the pin, whether high (1) or low (0).
If the digital channel mask is 0x0000, then these two bytes are omitted as no
digital I/O lines are enabled.
2 Analog
data set
(multiple)
Each enabled ADC line in the analog channel mask will have 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 channel mask is 0x00, then no analog sample bytes is included.
API frame support
I/O samples generated using Periodic I/O sampling (IR) and Digital I/O change detection (IC) are
transmitted to the destination address specified byDHandDL. In order to display the sample data,
