Embedded Linux imaging system
Worked on an embedded camera platform using uCLinux on an ARM7
processor core. During the course of this project Rob provided
S/W engineering support through the initial board bring-up phases
(NET+Arm Processor - Arm7 core with networking enhancements) then
as the project progressed, provided much of the low level driver
interface support (One-wire, DSP) and the application level programming
that gives this product its user functionality/personality.
Finally, he designed and implemented a set of inter-locking manufacturing
utilities and databases designed to automate most of the tests and
processes used in the manufacture of this product.
TriplePoint established a close working relationship with General Software
creators of Embedded BIOS 2000 and Firmbase. Rob is one of two primary BIOS
engineers at TriplePoint and has provided Embedded BIOS engineering support
to numerous clients. TriplePoint has been a General Software
Technology Partner since early 2000.

Rob provided S/W engineering support during the investigative phase
of a project to develop a host of products based on a short distance
low speed RF data communications channel. He wrote demo code for
several devices and provided bench-side debug support to the H/W
development team. Development was for a PIC processor and involved
peripherals such as simple switch key pads and multi-line LCDs.
VxWorks BSP and low level drivers
Provided software engineering services to a product team developing
a tablet computer and web browser. The tablet used the VxWorks operating
system and Rob was responsible for the BSP and several of the low level
device drivers (LCD, touch pad, buttons, clock...).
Software Engineering support - New board development
Provided primary software engineering support during the design and board
bring-up phase of a new StrongARM based board. During this development Rob
ported a bootloader/debug monitor to the board, developed the initialization code,
wrote debug code and provided bench side assistance/coding for the H/W
development team. Rob also wrote the initialization, bring-up and debug code
for all the primary subsystems (LCD, One-wire, touch pad, buttons...).
8051 embedded processor and Dallas One-Wire interface
Provided embedded 8051 firmware to interface to a Dallas OneWire bus. Rob was
responsible for all the S/W on a sub-system comprised of an 8051 controller and
Dallas semiconductor One-Wire devices. The sub-system was used to provided
serial number and environmental data to an Pentium based system installed in
stadium seat-backs. Rob was responsible for the entire 8051 portion of the
project in addition to the Pentium interface libraries used communicate data
to the higher software layers.
Driver suite and test tools for manufacturing test fixture
Created a suite of Windows 95 drivers (network and printer) and access DLLs
in support of an automated manufacturing test fixture used for final test of
a home PNA product.
Sample SMBus Driver
Rob was contracted by a principle in the SMBus Consortium to create an architectural
sample driver for SMBus devices. The base driver is provided by the consortium as the
sample for creating other SMBus drivers. Rob redesigned the existing
monolithic SMBus driver to accommodate a miniport/class driver model.
The project included several test apps and an ASL test harness.
Software engineering support - BIOS
Provided software support for all BIOS and low level functionality
(flash update, card services...) for line of dedicated
purpose hand held PC. Rob acted in the capacity of sole S/W support
engineer for three handheld products, provided support, debug
and continuing development engineering.
Driver suite and test tools for manufacturing test fixture
Created a suite of Windows 95 drivers (network and printer) and an access DLL
in support of the automated manufacturing test fixture used for final test of
a home networking product.
Real-time firmware for a home networking product
Designed and implemented several complete subsystems of the operational
firmware for an home networking product. The product was based on the
StrongARM processor and was built under uC/OS. Rob was a key architect of
the overall system and had coding responsibility for the memory management
code, the low-level link code, printer pass-through, and several utility and
Handheld PC-compatible computer
Rob was responsible for all software and integration tasks in the development
of a handheld computer. BIOS, ROMed DOS, Flash file system, touch screen,
radio modem and Windows 3.1, Rob developed, customized, acquired and integrated
the complete software suite for this handheld platform device.
Developed a Windows NT 4.0 NDIS 3/4 driver for an integrated Ethernet/SCSI
ISDN PRI driver
Developed NDIS WAN driver in support of a dual ISDN PRI interface card.
Required NDIS, TAPI and call management functionality. Also implemented an
advance (at the time) system management interface to board level data and
Phoenix BIOS customization and adaptation
TriplePoint was named a Phoenix Independent Authorized Developer (IAD) for the PICO
and NuBIOS products in 1996. Rob attended the Phoenix BIOS training (twice) and has been
providing customization and adaptation services since 1996. Rob's Phoenix BIOS experience
is extensive (see below). He has several years experience in BIOS maintenance, new feature
implementation, chipset porting, and new product development.
ISDN BRI driver
Developed a "binary compatible" (Win95/WINNT 4.0) ISDN WAN driver in support of an ISDN BRI
interface card. Implemented the NDIS and TAPI functions to support this 2B+D card. In addition, the
driver was required to support HDLC over the D channel.
Pacemaker test and validation system
Rob provided design and programming to develop a test and validation suite for a very large
manufacturing test product designed to collect the parametric data on medical pacemakers.
The device consisted of more than 25 individual instruments, a ladder of relays and a custom
test head. Rob's software was responsible for polling each device for status, testing individual
components for accuracy, logging data and keeping statistics on system performance.
Novell Netware driver
Corrected and enhanced a Novell Netware driver to allow it to pass the Novell certification tests,
increase performance, enhance the local statistics gathering feature and implement "homing" (multiple
adapters could be selected to recover and take over upon failure of the currently running adapter).
