- Can based domotic system using TMS320F243 controllerPublication . Metrôlho, J.C.M.M.; Pereira, António; Costa, Mónica; Cardoso, José C.; Lopes, EuricoThe increasing demand of comfort levels in the home area stimulates the development of systems to reach several goals. Some features of this kind of systems are: energy savings, environmental control, safety monitoring, remote definition of the system set points, etc. This kind of systems is made up of several units spread in the target areas of the house where they are implemented. Those units communicate between them and the master stations through different sort of links: cable, radio frequency, optical fibre, power line, etc. Also, they can use different kind of communications protocols like: Controller Area Network (CAN), Profibus, Bitbus, user defined, etc. To implement the mentioned systems there are a large quantity of devices, furnished from several chip manufacturers. For example, T exas Instruments as Digital Signal Processors (DSP) that have embedded CAN modules to allow easy and powerful solutions like for instance the improving of motor control applications using the above-mentioned communication protocol. This paper describe a CAN based system that uses a DSP Controller and allows the control of several actuation/acquisition devices that form a flexible, robust and easy maintained Domotic network.
