RESUMO

In recent years, there has been a major adoption of digital signal processors (DSPs) technology in a variety of embedded control applications. Typical industrial applications include high-performance servo drivers in applications like machine tools and robotics. Beyond the processing power, modern automation technology is characterized by increasing decentralization of data processing. But, the necessity of communication between the different systems has also led to the development of medias more efficient as Controller Area Network (CAN Network), that was initially created by Robert Bosch in the mid-1980s for automotive applications as a method for enabling robust serial communication. In this work, the development of the communication between embedded systems based in the two layers of CAN network is argued. For in such a way, a CAN network using DSPs was developed and, for validation of the work, an application of the network in Automatic Guidance Vehicles (AGVs) was developed. Where some of its more elementary functions, which had been emulated in the net formed for DSPs, through the development of specific libraries had been selected.
