Consultants to the Electronics Industry
Specialists in Embedded Microcontroller Development
What we do...
Robert Marshall & Associates, incorporated in 1982, is involved in the design and development of electronic product from inception through production. The design group expertise spans the areas of digital control systems, rf technology, pcb design, mechanical design and packaging.
Application areas include the 12-volt automotive industry, cellular and pager technologies, biomedical and utility systems, industrial controls, security, motion controls, specialty printers and scanners as well as sensor technology and remotely controlled systems. Firmware development is in 'C' unless assembly language is specifically requested or needed due to timing constraints. Schematic capture / Pcb layout is typically done in Altium Designer.
Areas of Expertise
Areas of expertise include multi-processor, multi-tasking embedded controller design over many years of extensive development experience utilizing Microchip micro-controllers and KEELOQ, Atmel microcontrollers and CPLDs, National microcontrollers, security, rf, analog and digital circuit design, pcb layout, and mechanical design and preparation for production.
