I have had firmware experience with the following microprocessors.

Intel 8051

In 1997, I wrote prgrams to test a circuit board which handles communications to fiber-optics test equipment. Used 8051 assembler and C.

In 1987, I wrote programs to control a medical laser using 8051 assembly language.

In 1987, I wrote programs to network communication between a hand-held control module and medical imaging equipment using 8051 assembly language.

Motorola 68331 and HC16

In 1993, I wrote subprograms that were embedded in a digital audio mixer used by the television industry. Used Motorola 68331 and HC16 assembly languages and C. Programs included LCD display, a floppy loader, and user-input handlers. Coded software to control hardware chip select signals, watchdog timer, interval timer, serial communication, and the Intel 82077AA floppy microcontroller.

Intel 8086

In 1988, I wrote a special-purpose BIOS for a company's proprietary product using 8086 Assembly language. BIOS also included control of 8250 UART, 8254 Timer, and 8259 Interrupt controler. Extensively used Intel's I²ICE.

Other embedded skills

(With each new contract, I learn new material. Some material is unique to the client's product, and some is of a general nature. It is my firm policy NOT to charge my clients for the time I spend learning skills of a general nature.)

Embedded firmware includes a wide range of different specialties for different microprocessors and microcontrollers. I do not charge for my time to learn new architechtures. If a project requires me to learn Lab View, it may cost me more, but it should not cost you more.
