Project:
Serial Port Protocol stack
Location:
Nexgenix India Pvt. Ltd., Mumbai,
India
Client:
Swatch,
Switzerland
Description:
This
is a protocol stack for communication between watch and PC. This protocol stack
guarantees reliability and error free communication over serial port. This will
understand queries asked by PC and will respond to it after processing the
command. Flow control and error detection are
implemented in this stack.
Responsibilities:
Ø
High-level
design of Protocol stack.
Ø
Coding
for Protocol Stack
Environment:
C, ADS (ARM Developer Suite), Multi-ICE, Nucleus OS

Project:
Virtual Keyboard
Location:
Nexgenix India Pvt. Ltd., Mumbai,
India
Client:
Swatch,
Switzerland
Description:
The
virtual Keyboard is designed to allow user to enter the text using just 5 Keys.
This is like the interface used to type SMS in mobile phones. It includes “T9
dictionary” mode and “Multiple key press entry” mode. The “T9 dictionary
mode” allows user to enter the text efficiently with less keystrokes. In
dictionary mode if there are more probable words for same key sequence, then
user can select the word he/she wants. The virtual keyboard allows user to enter
special characters and numbers as well.
Responsibilities:
Ø
Designed
UI for virtual keyboard
Ø
Coding
for complete virtual keyboard
Environment: C, C++,
ADS (ARM Developer Suite), Multi-ICE, Nucleus OS

Project:
FTP Profile in Bluetooth Stack
Location:
Nexgenix India Pvt. Ltd., Mumbai,
India
Client:
Swatch,
Switzerland
Description:
The
requirement of the project was to implement file transfer between PC and watch
using Bluetooth. GOEP and OBEX layers, which are lower layers in this stack,
were already developed and were available as a library. This layer acts like an
FTP server. It accepts requests from lower layers and responds accordingly. Also
it communicates with local file system to perform File related operations. It
can give a list of files that are available on watch. This layer allows putting
the file in watch, getting any file from watch and deleting files in watch using
Bluetooth.
Responsibilities:
Ø
Designed
& Developed FTP layer in Bluetooth Stack
Environment:
C, C++, ADS (ARM Developer
Suite), Multi-ICE, Nucleus OS
4.
Project:
MPEG4 streaming Media player for Embedded Devices
Location:
Nexgenix India Pvt. Ltd., Mumbai,
India
Client:
Swatch,
Switzerland
Description:
The objective for this project was to port an MPEG4
module, which allows streaming and playing an MPEG-4 movie on the target
board.
This module was already ported on one of the development
boards. It was required to port it on new development board. Project involved
porting of DIVX library for video and AAC library for audio on the target
board.
Responsibilities:
Ø
Porting
of MPEG-4 Module.
Environment:
C, C++, ADS (ARM Developer Suite), Multi-ICE, OS – Threadx
My Projects at
Kelcom Labs
1.
Project:
Light
Processor
Location:
Kelcom Labs, Pune, India
Client:
Anquetronics,
Mumbai
Description:
The
Light processor can be used to give special light effects with different light
sequence combinations. The user can program different combinations and can run
multiple combinations at a time. It has 128k bytes of ROM, which can be used to
store different combinations of light sequences. The user can adjust the sliders
provided to change the intensity of lights and also observe the output at the
same time. This is useful while programming the sequences.
Responsibilities:
Ø
Emulator
design for light mixer in VC++. This will simulate the light mixer on PC.
Ø
Design & coding of
firmware.
Environment:
C, Cygnal
IDE 1.85, Keil Compiler
2.
Project:
PIC Microcontroller Programmer – Kelstart SE
Location:
Kelcom Labs Pune,
India
Description:
Kelstart
SE is a programmer for Microchip PIC microcontrollers. It supports almost all
the 12 and 16 series of PIC microcontrollers. This programmer is compatible with
PICSTART PLUS. (PICSTART PLUS is a PIC programmer from Microchip). It can be
used with MPLAB IDE to program microcontrollers.
Responsibilities:
Ø
Implemented
complete firmware.
Ø
Reverse
engineering of a complete assembly code.
Ø
Implemented
serial protocol for Kelstart SE to get identified as PICSTART PLUS.
Ø
Stepwise
implementation of two programming algorithms. (Different algorithms are used for
different types (Flash, OTP) of microcontrollers)
Environment:
C, MPLAB IDE on Windows 98, XP, Microchip ICD
3.
Project:
RFID Reader
Location:
Kelcom Labs Pune,
India
Description:
This
module is heart of RFID Reader System. With External antenna, Level translator
for serial port and power supply this can function as RFID reader for HITAG2
based transponders. The RF communication is at 125 KHz. The reading range is
4”.
This module can function in two modes-
Standalone and Host mode. In standalone mode Serial Numbers are already stored
in EEPROM and it can function on its own. In Host mode, it is connected to a PC
and after receiving Serial Number, sends the number to PC. The software on PC
identifies the Serial Number and sends decision to module. Also in this mode
user can read from / write into Tag’s pages. External relays and LEDs can be
connected which can be driven by module to indicate the decision.
Responsibilities:
Ø
Implemented
a State Machine for decoding incoming data.
Ø
Implemented
serial protocol for communication with Host.
Environment:
C,
MPLAB IDE on Windows 98, XP, Microchip ICD
4.
Project:
CDI Analyzer
Location:
Kelcom Labs
Pune, India
Description:
This
is a simulation model of Electronic Ignition System used in Automobiles. This
instrument is used for checking performance of CDI (Capacitive Discharge
Ignition) Units. It forces CDI to generate spark and measures accurate Spark
Ignition Timings and compares them with Ideal values. User can input any Engine
RPM Value up to 9000 rpm; unit simulates that situation and displays error in
Actual Spark Timing and Required Spark Timing at that particular Engine RPM.
Results are displayed on LCD. It also communicates with PC for storing complete
test results
Responsibilities:
Ø
Developed
simulation of an “Accelerator” giving rpm as input to simulation of an
Engine.
Ø
Developed
driver for 16x2 Alpha-Numeric LCD display.
Ø
Developed
firmware for Spark sensing and Timing comparison.
Environment:
C, MPLAB IDE on Windows 98, XP, Microchip ICD
