Software/firmware design and development experience using the following processors: TI MSP430, TI C2000 (C24x & C28x including the 32 bit floating point controllers), ARM 7 & Cortex-Mx (NXP, ST, Atmel, Actel, TI), Motorola 68K, Coldfire, PowerPC and 56XXX DSP, Intel x86, i960 and 8051.
Engineering projects have employed the following toolsets: TI Code Composer Studio 3.X & 4.X (Eclipse based), IAR Embedded Workbench 4.X/5.X., Wind River Systems’ Tornado embedded cross development tools and VxWorks RTOS, Microsoft Windows CE Platform Builder. Experience in building embedded XP images.
Familiar with the control of galvo-driven mirrors, control of high speed (20 kHz) harmonically oscillating piezoelectric micro mirrors (and the development of resonant frequency seeking & keeping algorithms).
Experience with control of lasers for use in projecting optical patterns, including gating a laser off & on during coordinated movement of mirrors for purpose of raster based laser line projection; detection of laser faults during operation, and implementation of FDA & UL mandated laser safety protocols.
BLDC motor control using field oriented control and space vector modulation; familiar with the initialization and use of image sensors, the control of pneumatic devices. Design experience using the following peripherals: ADC, DAC, USB, I2C, SPI, PWM, Capture/Compare & timers, serial interfaces. Firmware project designs have also employed MEMS accelerometers and inclinometers.
Complex state machine designs & implementations used to control and manipulate precision imaging and milling systems. This included the design & development of runtime kernels, command processors, device drivers, and status/fault reporting systems.
ISP boot-loaders - in the field upgrade of firmware, flash erase & program algorithms. Design and implementation of Windows XP applications and modules used to upgrade firmware images in deployed systems.
Authoring of firmware design verification protocols and test suites, including automated script testing of firmware design requirements and the production of system level validation protocols.
Additional experience includes the development of Windows NT/XP kernel mode device drivers using the Windows DDK; Win32 console and GUI application design abilities using MS Visual C++, Win32 SDK, and MFC.
Familiar with software configuration management tools such as Perforce, SourceSafe, RCS, and PVCS.
Proficiency and training in software project management from the Schlumberger Laboratories for Computer Science.
