PROFESSIONAL EXPERIENCE
CIRQUE CORPORATION 2010 – 2012
Embedded Development Engineer
Individual Contributor for design and development of embedded software for Cirque's touchpad devices. All code was written in C, using MSP430, STMicro, Maxim, and Microchip PIC microcontrollers Extensive board bring-up and evaluation using oscilloscope, ICE, debugger, and logic analyzer.
Implemented a proprietary communication protocol embedded within an I2C communication protocol to enhance touchpad performance.
Upgraded existing touchpad products by porting them from a 6805-based platform to an ST Micro-based platform. Implemented PS/2 communication from the microprocessor to the Personal Computer. The touchpads were required to exactly mimic the performance of earlier products, and low-power features were incorporated.
Developed code for electrostatic discharge (ESD) testing.
Ported several existing products to new hardware/software platforms to test their viability as production-worthy products in cost-cutting efforts.
GREAT STUFF, INC, Austin, Texas 2008 – 2009
Embedded Development Engineer
Individual Contributor for design and development of embedded software for a hose reel motor controller and the wireless devices used to control the hose reel. All code was written in C, using two different MSP430 microcontrollers and two Si Labs EZ Radio devices.
Developed low power management software for all devices, using the low power features of the MSP430 and the Si Labs devices. Battery conservation was at a premium, as the hose reel must be ready to operate at a moments notice over months of operation.
Developed a safety feature that detects when the hose is impeded while being reeled in. This prevents the hose reel from tipping when reeling in at high speed.
Developed a communications protocol that allowed two remote controllers to send commands to the hose reel to program it to turn water on and off for daily watering. One of the remotes is attached to the hose reel, and the other is a hand-held device that the user operates.
Developed communications software to allow the hose reel to send commands to a watering valve that turns the water on and off.
Developed control software that allows a valve to turn a solenoid on and off to control water flow.
Radio communications software was developed to allow the hose reel to command the valve to turn water on and off. The valve communicates to the hose reel an acknowledgement when it receives a command and the state of the water on/off state.
Circuit debug and board bringup using the IAR IDE for the Texas Instruments MSP430 and an oscilloscope.
3M., Austin, Texas 2007 – 2008
Senior Product Engineer
Individual Contributor for design and development of embedded software for the 965 AMS Subscriber Loop Analyzer using Analog Devices 2189 DSP and the MCF5207 ColdFire microprocessor.
Analog Devices Visual DSP++ IDE was used to develop 2189 assembly code to generate sine waves and to perform transmit and receive calibration functions.
Debugged existing 2189-based circuit boards and a new FPGA design using an oscilloscope, logic analyzer, and the DSP++ emulator.
Performed board bring-up and developed C/assembly boot software for the ColdFire using the Green Hills IDE with a Green Hills Probe. The ColdFire replaced an obsolete processor in an existing design.
Performed software configuration management using the StarTeam Cross-Platform Client.
FREESCALE SEMICONDUCTOR INC., Austin, Texas 2004 – 2007
Senior Software Engineer
Technical Lead/Individual Contributor for design and development of real time embedded software for ARM/StarCore-based Motorola cell phones. The code consisted of C and assembly language that comprised the boot ROM, configuring and securing the phone before launching the application code.
Scheduled and assigned tasks for a seven-member international team of software developers.
Tracked change requests using DDTS.
Initiated and tracked Code inspections using DISSECT.
Performed software configuration management with Rational ClearCase and ClearQuest.
Key member of Linux Device Driver team, performing driver maintenance, updating all technical documentation, driving the move to a process-oriented work flow, ClearQuest administration, and managing code releases.
BITRODE CORPORATION, St. Louis, Missouri 2003 – 2004
Principal Software Engineer
Designed and developed real time embedded software and digital hardware to control battery formation and testing equipment.
Worked with power engineering experts to translate battery formation algorithms into embedded systems code.
Performed software development on two platforms; a ColdFire-based central controller communicated to racks of Microchip PIC controlled battery-test circuit boards over an internally developed high-speed serial link that was very similar to the CAN protocol.
Spearheaded bring-up and test of the central controller and battery-test circuit boards using a logic analyzer, oscilloscope, and Diab SingleStep Debugger. Software design included assembly language startup code, C language control and communication software, and development of interrupt service routines to manage peripherals and communication hardware.
POLYCOM, Inc., Austin, Texas 2002
