• Embedded Systems Engineer Contract

  • 1997 - 1999

  Redesigned (Refactored) the architecture of an existing product to use as a development platform for concurrent engineering purposes. Created and modified modules using UML standards and Case tools - dataflow, state transition, and flow diagrams before converting to firmware. These modules were then used for the development of several control systems. The modular code was then ported (using new addressing and hook variables) into new products which used completely different micro-controllers. One platform consisted of the RTXC (RTOS), and others using the Infineon (Siemens) 505, 167 micro-controllers. Developed a MFC\ATL\COM application, (Visual Studio 97 to v6.0), that controlled the truck ECU’s using serial communications (SAE J1587 and SAE J1939). Automated truck ECU algorithms, and flashed the control units, interfaced with 3rd party tools APIs, contained DSP filter for analog RF inputs, and control algorithms. Show less
