Portafolio

Professional Websites

* Built GUI for Raspberry Pi 3 on Python Tkinter
* Managed Modbus-TCP/IP and Modbus-RTU to establish communication between Raspberry Pi and Petrol Fuel Stations
* Fetch all the data on severs using Wi-Fi and Ethernet and GSM

Pyhton Tkinter GUI for Raspberry Pi 3 (with MODBUS Protocol)

* Setup aws server for IOT implementation
* Data logging of MQTT supported devices to communicate with server and access data remotely
* IOT core is used along with few HTTPs communication requests

IOT project - MQTT based devices on AWS server

* Implemented State-Machine in C++ Language to send various commands using UART to download data from Devices
* Permission to download specific device is obtained from server and the information is stored in MySQL database
* Data is downloaded from devices using UART and the downloaded data is sent back to server in JSON format using CJson Parser

MySQL/ C++ BASED APPLICATION

* Implemented Client – Server project using IPC mechanisms fifo, pipe, message queues
* POSIX threads are used which send the client requests to corresponding processing client using IPC mechanism Shared Memory
* Processing client processes the data and send the result back to thread in server which finally accept this result and send it back to Requesting Client
* This entire process is synchronized using binary semaphores

CLIENT – SERVER MODEL USING IPC MECHANISMS IN LINUX

* Developed GPIO drivers to control various GPIO pins of microcontroller to provide specific voltage on GPIO output pins
* Developed SPI driver from scratch to interface any slave device with STM32 microcontroller
* Developed UART driver to provide serial communication interface to the microcontroller for all other devices not supported by SPI drivers. It involved the use of Basic Timer and Watchdog for proper sync of the devices during communication
