Setting the Alarm Threshold Value
The Alarm Threshold Value is set in the low register of the channels.
Data
Registers
Data is stored in the input registers (30xxx series), which are read-only.
All data items are four bytes long and are stored across two registers.
Byte and word order for particle data is big-endian. Thus, data items
are formed by placing the high bytes in front of the low bytes.
Example:
<High Bytes><Low Bytes> = <4 Byte Data Item>
Analog data is little-endian. Thus, analog data items are formed by
placing the low bytes in front of the high bytes.
Example:
<Low Bytes><High Bytes> = <4 Byte Data Item>
Not all particle and analog channels are necessarily active. Retrieving
data from an inactive channel returns garbage. See the Data Enable
Registers section of this document for details on how to record data
from active channels.
This entire series of registers represents one data record in the device.
The Record Index Register (40025) must be changed to index other
records here.
