Computer Scientist Consultant Specializing in Microcontroller Firmware Design

Consultant #1533

Firmware design for embedded microcontroller products.
Digital signal processing (DSP) firmware and signal processing.
Real time, high speed embedded applications.
Programming in C and assembler.
Plan and manage projects from concept through design, debugging and documentation.
Proficient with multiple processors (Microchip PIC, Freescale DSP, Cypress PSoC, TI 430, 8051) and associated peripherals (A/D, D/A, etc.) and user-interfaces (LED, LCD, graphics), multiple busses and protocols (USB, I2C, RS232, RS485, IrDA, Modbus, modems, etc.)

Undisclosed Company, Proprietor, 1995 - Present

Developed multi-processor system for a machine safety application using Cypress PSoC (CY8C31434).
Designed keypads and stepper motor controller and sequencer firmware for an innovative ergonomic USB keyboard using Cypress PSoC (CY8C24994.)
Designed firmware to implement a family of 3-phase electric meters utilizing Freescale DSPs 56F826 & 56F8357 and Micrium's uC/OS-II real time kernel, gathering low-level measurements to calculate numerous power and energy values.
Delivered firmware designs for two subsystems in an electrical power monitor. LCD graphics display shows user-programmed screens with various power and energy values and companion intelligent modem module dials out when it detects out of limit events. Both designs utilize high-speed 8051 variants (Dallas C320, Atmel TS80C51U2), perform Modbus master and slave communications simultaneously on multiple ports, have flash download capability, and are implemented as concurrent event-driven state machines.
Developed programs for utilizing voice prompts to interact with the user of a consumer health care product (TI MSP430F149).
