Communications Applications Projects
Implement IrDa "Off-the-Shelf" Infrared Communications Package
In order to perform offline analysis, a medical device startup needed a simple and portable method for downloading data from their oxygen concentrator. The software had to use less than 20K of memory and run in a PIC microprocessor.
PacInfo selected a wireless infrared communications package, using OBEX protocol. PacInfo ported the driver code to the PIC Processor. Using the OBEX protocol, data could be transferred to any IrDA compliant infrared device such as a PDA as well as from the PDA to a PC for offline analysis.
Toolbox:
Language: Microchip C
Operating System: Microsoft Windows 2000
Microprocessor: PIC 18F8720
Hardware: Microchip 18F8720 development board;
ActiSYS IR wireless interface
Design and Develop I/O interface

Upgraded Client/Server Applications for MediCal Providers
Developed Test Software for Network Communications Board
Developed test software for network communications board based on the Motorola 68360 processor. This board used HDLC and other protocols and an on-board CODEC.
Toolbox:
Communications protocol: HDLC
Hardware: CODEC
Microprocessor: Motorola 68360
Develop Controller Software for Automotive Collision Avoidance System
Analyzed potential operating systems, platforms, and peripheral drivers for rapid prototype development requirements. Developed modular, object-oriented software quickly with substantial code reuse from previous project. Initial project emphasis was on ability to easily calibrate inputs and reconfigure displays in the field. Iteratively refined software as requirements were solidified through human-factors research and field testing.
