Designed the hardware for a 24V LED lighting system for use in the automotive industry.
Completed the hardware design for the three new boards.
Wrote the specifications and instructions required by an external CADSTAR designer.
Work with the CADSTAR designer to create a new library, produce the schematic circuit and design the printed circuit board.
Modified existing C/C++ firmware, running under the eCos RTOS, to correct the issues identified and improve the machine operation
Created a clock system that provided predictable timing intervals
Create a queued printing system to overcome erratic printing
Created a data logging system to collect data accurately
Maintained a good record of the changes completed
Completed the detailed hardware design for a new fire safety panel
Worked with the PCB designer to re-design the hardware parts library
Created the PCB design specifications and supported the PCB designer for component placement and routing
Supported a prototype PCBA manufacturer to supply pre-production prototypes
Wrote all test schedules and performed design validation testing
Wrote the firmware in C for an embedded Freescale processor to manage the real time communications between a PROFINET I/O gateway, a PC and a control processor running on the same board
I2C was used for the communication with the control processor, USB was used to communicate with the PC and RS232 was used to communicate with the PROFINET I/O gateway
Wrote the firmware in C for an embedded HTTP 1.0 web server running on an Atmel UC3 device
The application used the lwIP open source stack, in Raw API mode, to create and manage the TCP/IP connection
The server provided an interface to a web based control panel that allowed parameters to be set and read in a number of slave devices
An I2C interface was used to communicate with the slave devices
Other designs:
Completed cost reduction design and development work for transmitters and receivers operating with a 760kHz excitation signal
Designed the DC to DC switch mode converters that provided four DC output voltages
Supported the design of the printed circuit boards by external PCB designers
