UART
8.1
Logical data exchange
Data is exchanged over the interface in Big Endian byte order.
The general format of a data frame is:
Section
Code
Length UART Payload
Length
1 byte 1 byte (Length) bytes
The Length field indicates the length of the “UART Payload” in bytes.
8.2
Commands and Application data
There are two categories of frames exchanged, Commands and Application data:
Commands are frames accepted by the NEOCORTEC node.
Application data is data sent from the NEOCORTEC node to the External Host.
Some commands will cause values to be returned. These values are sent as application
data (frames).
Some data frames come from information received from another node in the network,
and as such it can be subject to long delays. The principle is that the application should
continue execution, and react on the return value based on the Application Data Code,
which associates it with the command previously issued.
If the command listed hereunder has a corresponding return frame, the Application
Data code is listed under the “Return” column. For a definition of these codes, please
