PROJECTS
1. Project name: Software development for Multihead packaging machine
Technology : embedded software development
Tools used : Keil 5
Language used : C
Hardware used : stepper motor, vibrator, loadcell, HMI
Description :
The multihead packaging machine is an embedded product used for accurate and
high speed packaging in food industry. It works on the concept of combination
weighing algorithm. The machine has three major parts.
3.
o A main card(LPC 1758)
o Multiple slave cards(LPC 1754) connected with main card via CAN bus
o Multiple ADC cards(LPC 1114), each connected with a slave card via
MODBUS
The main card is connected with peripherals like EEPROM (via I2C) and HMI (via
MODBUS). The task of the main card is to boot up all slave cards, to receive HMI
commands and periodic information from slaves card and to control slave card
operation based on user inputs from HMI, GPIO inputs and periodic data.
The slave card is connected to two steppers, a vibrator and an ADC card. The main
function of slave card is to control peripheral in various ways based on the
command received from main card and periodically query weight data from ADC
card.
The ADC card is connected with ADC (cs5532) via SPI. The task of this card is to
initialize ADC based on given parameters from slave card, fetch ADC data
continuously and respond MODBUS queries of slave card.
Responsibilities in project:
Design, development, testing and bug fixing, deployment and support
2. Project name: Development and testing of a l2/l3 layer features of SDK for
programmable networking ASIC
Technology : Embedded software development
Tools used : Spirent, Ixia
Language used : C++, C, Python
Hardware used : Bare metal boxes with customized networking ASIC
Description :
This project involves development of SDK for customer defined programmable networking
ASIC. The SDK development is done in C++. It involves supporting various L2/L3/L4 layer
features and SDN compatibility. The SDK also included support for Switch Abstraction
Interface (SAI) of OCP. The project also included SDK testing, networking feature testing for
customized networking switch, and simulation of software switch, which can be used to
test protocols at initial level, before chip fabrication, for reducing time to market.
Responsibilities in project:
Feature and primitive manager development as part of control plane SDK
development.
Development of the MIPS 4K firmware for service CPU assisting main CPU.
