Abstract: An apparatus used as a platform for Developing Embedded Real-time Software with a laptop or a Personal Computer, multiplicity of USB to CANbus converters, multiplicity of USB to RS-232 converter, multiplicity of single board microcontrollers, Interface board interfacing the microcontrollers, and software development tool-chain. The preferred embodiment uses at least one of the microcontrollers as the System Controller, and at least one microcontroller as the Plant or System Under Control. The interface board acts as signal conditioner, between the System controller and the Plant. The serial interfaces are used to download executable code into the microcontrollers, observe the overall system behavior, and inject faults or failure into the plant model.
