Running uBACstac device on Arduino Mega with an  RS485 Module

Check out our latest video about uBACstac. In this video we ran a complete B-AAC device made with Cimetrics uBACstac - BACnet Protocol stack for small devices on Arduino Mega 2560 with RS485 Shield Module.

When you buy uBACstac you will get the source code and can easily make BACnet device of your dream.

We used uBACstac Software Development Kit which consists of a source code library and documentation for BACnet device development, especially for embedded devices (firmware development).

It supports the following BIBBS: DS-RP-B, DS-RPM-B, DS-WP-B, DS-WPM-B, DM-DDB-B, DM-DOB-A,B, DM-DCC-B, AE-N-I-B, AE-ACK-B, AE-INFO-B, SCHED-I-B, DM-TS-B, DM-UTC-B, DM-RD-B.

This device has 13 objects - Device, Analog Input/Output/Value, Binary Input/Output/Value, MultiState Input/Output/Value, Notification Class, Calendar, Schedule.

uBACstac library supports the following BACnet profiles: BSS, BSA, B-ASC, B-AAC. Our example supports B-AAC profile.

This is an MS/TP master device.

We used free Cimetrics BACnet Explorer to discover the device.

We used BACnet IP to MSTP router B6000 to route from Arduino to BACnet IP. 

We used Cimetrics BASomatic protocol analyzer to sniff the traffic. 

We used Arduino IDE software to upload it to the board. 

We used GNU toolchain for coding: WinAVR for Windows and gcc-avr for Ubuntu Linux.
