Implementing Simple Protocols In Multiple Processors Control Applications

Using microprocessor/microcontroller in various control applications is not only one of the major topics in Engineering Technology curricula, but also of interest in industry applications. To accomplish it correctly the process of designing application programs starts from the individual module development through extensive testing, verification, and modification. Applying these developed modules in a useful manner requires the links and integrations that lead to the practical project implementation. Frequently, in students’ senior project designs and faculty’s research plans, the microprocessor/microcontroller resources become scarce or cause conflicts during the modules’ integration stage. To accommodate the shortfall of the resources and resolve any conflict state, several choices must be considered, such as the need to revise or totally rework the module, or apply the module with additional circuit design. This article presents a proven concept that implements the simple serial communication protocols in a multi-processor environment, which aims to keep the pre-developed modules intact with the least possible modification when they are integrated into the project.
