1.
Developed a customized flash-loader for MC9S08QG4 microcontroller
which downloads the application firmware from a 32 bit DSP,
TMS320F2810:
Description:
The
project was innovative since the master of the flash-loader (DSP) was
connected to the slave (MCU) through only two wires, which supplied power to the
wheel end sensor using a regulator circuit. Since the MCU used to get reset if there is
no supply for sometime, data bytes were transmitted from the master to the slave
using

bit DSP from
Description: The process of
bootloading where the master and the slave belonged to
entirely different family of processors was an innovative approach and as such
it is considered for patent by Dana Corporation. The
master of the bootloader calibrated the slave
(MC68HC908QT4) and sent commands like erase and program to it through SCI serial
communication protocol. The slave
side code (written in assembly language) performed ‘erase’ and ‘program’
functions using its background ROM routines and sent acknowledgement using
software SCI protocol. The master took the hex bytes from the .s19 file of the
application code and sent them to the slave for programming.

main ECU. The MCU received data from MC9S12D64 16-bit microcontroller which was
the heart of the ECU through software
SPI communication and
depending on the data received, enabled or disabled the fail safe lines.

Developed firmware for the fail safe module of the ECU of a trailer
which used a 16-bit Mixed signal processor viz. MSP430F1232IPW as its main
controller:
Description: The 16-bit MSP controller accepted analog
signals from several protective units like smart high side power switches of the
ECU and the TIMS (Tire inflation management systems) modules, converted them to
digitals signals using its 10-bit ADC converter and then sent them as packets of
data bytes to the main DSP controller of the ECU using software SCI serial communication
protocol. The MSP also
verified if the system was working properly by checking for valid messages from
the DSP every 10 ms and kept the fail safe lines enabled, or disabled
accordingly.

trailer:
Description: The Wheel End Sensor was an active
device placed in the wheel axle of a trailer which provided wheel parameters
like wheel speed, rotation direction, temperature, acceleration, etc. to the
main ECU of the trailer using a standard two wire interface. The device actually
was an electronic circuit consisting of an 8-bit MCU MC68HC908QT4, which
accepted real time wheel end signals, processed it and transferred the
information to the main ECU module using PWM
encoding.

Development of firmware for Electronic Control Unit (ECU) of a trailer (On
going project):
Description: The
innovative feature of this ECU is that it introduces a design which can
simultaneously deal with both Antilock braking system
(ABS) and Tire Inflation Management system (TIMS). This design is expected to be
economical and less spacious as ABS and TIMS design system will utilize many
common resources. The ECU uses a 32-bit DSP manufactured by TI viz.
TMS320F2810PBKA as the main controller and a 16-bit MSP viz. MSP430F1232IPW as
the controller of its fail-safe module. Worked on developing firmware for various
modules of the ECU like implementing SCI serial communication using FIFO and
stack features to communicate with the fail safe module and developing firmware
to receive PWM encoded data from wheel end sensor using capture interrupt.

Final Year Project:
Measurement of air flow rate
through high pressure tunnel using fiber optic sensor.
Description: The project was innovative since it uses the microbending property of optical fiber to measure air flow
rate. When air flowed through the tube at high flow rate the optical
fiber sensor placed inside the tube underwent microbending due to air pressure on it and as a result the
intensity of light passing through the fiber decreased in proportion to the air
pressure, which was detected by a photo detector. The output thus varied as a
function of the air flow rate through the tunnel.

Mid-term
Project:
Devising a Microprocessor (8085) based Object
Counter. Both Hardware
Designing and Software development using assembly language was implemented to
devise the Object Counter.
Description: The light emitted by an LED was
obstructed by the objects (to be counted) one after another and the obstruction
was sensed by a light sensitive diode whose resistance changed when light did
not light fall upon it. The change of resistance was converted to change of
voltage level that was detected by 8085. The no. of times voltage level changed
gave the number of objects.
