Embedded Engineer (Full-time) Oct 2018 - Present

Embedded-C programmer for development of projects according to customer requirements

Interfacing various peripherals to microcontrollers using drivers such as SPI, UART, USB

Developing user friendly representation in the screens for Human Machine Interface.

Testing the products for their faultless, e cient working and Documentation of projects. Projects

Battery Data Logger:

Monitors and records the battery temperature, current and voltage during battery charging. Hardware: STM32F070, LM35, WCS1500, LM2576HV.

Read the temperature, current from respective sensors and battery voltage using internal ADC.

Converted the obtained voltages into corresponding battery temperature, current and voltage.

Stored the obtained values from RTC into an SD Card every 5min into a le using FATFS.

Transferred datalog to the user through USB virtual COM port when a command is received.

Digital Circuit Board for Cable insulation Spark Tester: It plays a major role in monitoring the digital and analog inputs used in cable insulation test. Hardware: STM32F417, MCP3204, MCP4821, MAX485, SI8641BB-B-IS1 optocoupler.

Interfaced ADC and provided analog output using DAC upon satisfying certain conditions.

Implemented MODBUS slave communication protocol at MCU for interaction with HMI.

Communicating with HMI, scanning the inputs, output register values at regular intervals.

Designed Delta HMI screens implemented user-friendly representation of di erent parameters.

Gas monitoring device:

An 8-channel microprocessor based multipoint monitoring and alarm system, scans eight independent industrial inputs of various types. Hardware: 89E516RD, 8279, LM2576, 74LS138, 7400, ULN2803, MCP3201, MCP4921, AT24C512 EEPROM, RS485.

Implemented latch functionality to hold onto the alarm indications until user acknowledgement.

Examined di erent circuits and resolved various issues in the boards ensuring timely delivery.

Improvised and nalized the product documentation with good representation for settings.

Electrostatic precipitator(ESP) controller:

Controls the carbon emission into the atmosphere by applying variable voltage to the thin metal rods present between the collecting metal plates. Hardware: PIC30F6014A, MCT6, OP07, INA117, MCP1415, LM311, LM317, 74LS245, RS485.

Formatted technical document by adding more information and created test documentation.

Updated the parameter features of the program in an orderly way for customer ease of use.

Analysed various circuits by xing the errors due to Integrated circuits and other components.

Relay card:

Measures the dimension of required product and is used in manufacturing industries to replicate the product dimensions. Hardware: PIC18F46K22, MAX232, relays.

Receive commands from RS232 in 8 bit format and process the relay outputs accordingly.

Implemented test functionality for checking the circuit operation and automated the process.

RS232 -RS485 converter:

It is used for converting proprietary protocol into RS485 MODBUS communication protocol for multiple serial devices communications. Hardware: Rabbit controller (RCM 3110), LM317, LM2576, ULN2803, MAX232, MAX485.

Read and write data into the ash memory of the small sector ash device in the form of bytes.

Simulated the board functionality by sending data and received data through resp. simulation.

Bookstore Application Self project:

Stores the details of all the books into a database, which can be used to maintain the datalog of books, making it handy to search for available books.

Programmed GUI for reading books entry and store it in a database using PyQt5 and SQLite3.

Implemented insert, delete, modify functionality and search the book with any known details.

Snip and search tool Self project:

Snips a selected section of the screen to extract the text/numbers, stores the data into a le by copying and provides the feasibility to search the selected text.

Programmed GUI for snipping a screen section containing text, numbers using PyQt5, OpenCV.

Implemented a web search function for the text recognised with webbrowser, pytesseract module.

Webcam Motion Detector Self project :

Detects the movements of objects and stores the details into a le, thereby representing the information in graphical format.

Detect the moving objects from Webcam, indicate the contours and store the details in a le.

Generate Bokeh graphs from the values of object movement using OpenCV, Pandas and Bokeh.
