and Delphi Engineering Group's Fibre Channel PCI and PMC cards. Software
implemented in C programming language using Texas Instrument's 'C40 real-
time support library and using GO-DSP's Code Composer for compiling and
debugging.
Customer: Delphi Display Systems Worked with software and hardware team
writing C code hardware drivers for Order Conformation System, OCS. The OCS
is a custom ruggedized display system that display's drive-thru customer's
order as well as advertising audio-visual media. Developed sensor API and
DOS drivers using C and '86 assembly code. Sensors included: temperature,
