PROJECTS:

Embedded System Design using Renesas RX63N:

-Data transmission through CAN protocol: Implemented CAN bus protocol for communication between two Renesas RX63N development boards and debugging using Digital Oscilloscope.

-Designed game ‘TOP GUN’: Interfaced LCD and switches with RX63N and developed a game using bitmap images to save the plane from travelling obstacles.

-Designed Virtual Pet: Designed a virtual pet on RX63N using various available peripherals like accelerometer, switches, LCD, ADC, Mic and UART. The project had use cases for all peripherals.

Real Time Priority Based Pre-Threaded Web Server: Hosted a real-time web server (tiny) that interacts with web clients through a pool of POSIX threads using producer-consumer model. Used FIFO policy to schedule the connection requests from the browser. Successfully implemented high priority to the server and low priority to the client threads. This web server could host both static and dynamic content.

RaspberryPi based Home security system: Anti-theft face recognition security system with face detection and image capturing in case of mismatch and uploading to Dropbox using OpenCV and broadcasting an alert through RaspberryPi 2.

Programming bare-metal ARM with QEMU: RTOS (Real-time operating system) projects in building of Linux kernel image for ARM versatile board and building root file system with Busybox.

Shortest communication Network Path: Successfully computed best path in network following Open Shortest Path First (OSPT) using Dijkstra’s Algorithm. The best path was determined using the criterion of minimizing the total time taken by data to reach the destination. Network topology can change as per state of links and routers.

Data logger using Xbee Wi-FI: Interfaced Renesas RX63N board with Xbee Wi-Fi module to send sensor data to SparkFun’s web server to setup data stream and maintain data log.
