Programming Considerations
implements layers 2 to 5 (and part of layer 6) of the LonTalk protocol and
provides the physical interface for the L
ON
W
ORKS
communications channel.
A simple serial communications interface provides communications between the
ShortStack Micro Server and the host processor. Because a ShortStack Micro
Server can work with any host processor, you must provide the serial driver
implementation, although Echelon does provide the serial driver API and an
example driver for a specific host processor. Currently, example drivers are
available for an Atmel ARM7 microprocessor and an Altera Nios II embedded
processor.
For ShortStack device development, you use the C programming language. You
use the Echelon LonTalk Interface Developer utility to create the application
framework. Your application uses an ANSI C API, the Echelon LonTalk
Compact API, to manage communications with the ShortStack Micro Server and
devices on the L
ON
W
ORKS
network.
See the ShortStack FX User’s Guide for more information about the ShortStack
Developer’s Kit.
