2. PROJECT DETAILS
1. NGI K256:
NGI K256 is about the Radio used in Cars.
Two microcontrollers are used.
One 32-bit Renesas microcontroller RH V850 is used as VIP(Master) and other ARM processor is
used as HOST(Agent).
VIP is responsible to change the Radio power modes and System states as per the user interaction
such as Power button press and environment conditions
such as battery abnormal conditions, driver door condition etc.
VIP is responsible to wake up the Radio and shut down the radio as per the request from ARM or
during abnormal conditions.
VIP is responsible for Faceplate illumination.
VIP is responsible for Drivers and HAL layers.
IPCL mechanism is used to send messages between HOST and VIP to communicate using SPI
protocol.
As a team member, my responsibility was to:
• Implement the software in VIP Master as per requirements and deliver to customer
on time.
• Work as per the planned activities in Agile.
• Prepare Design documents.
• Bug fixing.
• Test case preparation.
• Perform Integration test for every release.
2. Talladega(Seeding Machine in John Deere):
The planter system is based on distributed network of 16bit controllers [Infineon XC2288] and
communicate on CAN network.
Consists of following modules
VT: It is John Deere 2630 Display used for user inputs and outputs, diagnose purpose, displaying
alarm mask. It has inbuilt Task controller for Auto track functionality.
EPG: Electric power generation module developed in matlab responsible to generate power for
implement side of tractor[planter] consist of n number of RUCs. It consist of closed loop control for
flow and pressure control to control speed, displacement of hydraulic motor and hence in turn the
alternator output which is power.
RUC: Row unit controller is mounted on each row of planter responsible to actually plant seeds
and work in coordination with MMC.

3. MMC: Meter master controller on implement side responsible for controlling and monitoring
various system performance parameter such as row spacing, singulation, COV, Skips, Doubles
etc. and also coordinate with RUC, Display and Task controller.
User will set various inputs like target population, seed type etc. by using Display.
Once implement is connected to the tractor then the auto implement detection will be detected
and offset parameters will be loaded in MMC for GPS communication. And once you start the
planting mmc will send Enable command to RUC’s. Ruc‘s will start planting and will send all real-
time values to the MMC ,by using this values MMC will display the graph, on Display. And MMC is
responsible for displaying Alarms, DTC’s for any failure modules or not in range values.
MMC will communicate with task controller to show the actual planting status in display using
GPS.
As a team member, my responsibility was to:
• Requirement analysis and Documents update for EPG and MMC
• Design and Development for MMC (ECU) and Display
• CAN log analysis for MMC, Display and RUC communication.
• Code review.
• Generating manual and automated test cases using Allsim ,CAPL Scripting.
• Verifying & validating the test cases in SIL.
• Regression Testing.
• Hardware setup
• Demonstrating the user stories to US team for acceptance.
3. Ezeetap
Ezeetap is a device similar to Billing machine. Collecting the card data, customer
information like name, mobile number, amount, displaying the details at each level on GLCD,
encrypting the Card details and amount and sending the data through a mobile Sim Card to
Server for billing.
As a team member, my responsibility was to:
• Develop a module for collecting the data from the user through keypad.
• Display the data on the GLCD by calling GLCD module functions.
• Develop a module for collecting the debit card details from Magnetic Swipe
Reader.
• Develop a module for encrpytion of the data using the AES encryption.
• Transmit the encrypted data thorugh DTMF tones.
• Involvement in integration.
• Performing basic sanity testing.

4. 4. EMLOG:
EM-LOG is based on the electromagnetic principle that voltage is induced in a
conductor by a moving magnetic field. A log containing an electromagnetic sensing element is
extended below the hull of the vessel which produces electromagnetic field. By using water as
the conductor, voltage is generated as the vessel progresses, relative to the speed through
the water. This Analog Input Voltage is read by using ADC MAX1301 (16-bit) and using the
digital output data Speed, Total Distance & Trip Distance are calculated and displayed the
three values on 7-segments display board. These three values (Speed, Distance & Trip
Distance) which are displayed on 7-segments display board are updated every 5 seconds.
Distance & Trip Distance values are written into EEPROM for every 5 seconds. The values
(Speed & Trip Distance) are even sent to repeaters through SPI, at 4800 baud rate for every
5 seconds through MAX3100. These values are sent in NMEA string format. The Speed value
is also sent in NMEA string format to terminal at 4800 baud
rate and 400 pulses are generated for indication of covering 1Nm Distance.
As a team member, my responsibility was to:
• Develop an application for interfacing the ADC to microcontroller and reading the digital
output from ADC, calculate the Speed, Distance and Trip distance and display these 3
values on 7-segment led display board.
• Develop a module for storing the Distance and Trip distance values in EEPROM using
SPI protocol.
• Sending the data to the repeaters by calling the module functions which contain
transmition in NMEA string format.
• Involvement in integration.
• Performing basic sanity testing.
