Abstract
In this work the proposal of an hybrid microcontroller network is presented, whose main application is oriented towards the implementation of a functionally distributed system, which is commanded from a personal computer (PC), where a program developed for the Windows graphical environment is executed and acts as System Monitor supervising the events related to the indebted operation of the network, unfolding numerically and graphically from the information that handles to node level and the present status of the network. The network was implemented under the common bus topology and the application includes the physical layer handling under the RS-485 standard used in the connection between each considered microcontroller node, as well as different microcontroller families such as Motorola, Microchip and the AVR of ATMEL are used.
Keywords: Microcontrollers, Distributed Systems, Microcontroller Netwok.
