Analog
sample
21-22 If the sample set includes any analog I/Olines (Analog channel mask > 0),
each enabled analog input returns a 2-byte value indicating the A/D
measurement of that input. Analog samples are ordered sequentially from
ADO/DIO0 to AD3/DIO3.
Example
In the following example, the device receives an I/O sample with an analog and digital I/O from a
remove device with a 64-bit serial number of 0x0013A20040522BAA and a 16-bit address of 0x7D84.
If you enable pin AD1/DIO1 as an analog input, enable AD2/DIO2 and DIO4 as digital inputs (currently
high), and enable AD3/DIO3 as a digital output (low) the I/O sample is shown in the API example in the
following table.
