  • Acquired expertise in HDSL and EnDAT encoder protocol interface, extensively utilized in robotics and industrial communications.
  • Enhanced scalability of HDSL interface, enabling support for single to multi-channel (up to 6 channels per ICSS module) and expanded PRU core clock frequency from 225 MHz to 300 MHz
  • Reduced firmware IMEM footprint for HDSL interface by 25% through code optimizations and utilization of additional lookup tables.
  • Took ownership of and supported customers for HDSL, Tamagawa, and EnDAT encoder protocols.
  • Consistently integrated quarterly SDK releases.
  • Mentored new hires and interns in encoder protocols, including EnDAT 2.2 safety up to SIL-3 level utilizing SPI interface.
  • Created and executed comprehensive project plans for interns, ensuring timely project completion.
  • Showcased new development to the entire software team through live demonstrations.

Embedded Software Engineer Intern

Texas Instruments
Bengaluru
01.2022 - 06.2022
  • Developed a 32-bit RISC PRU implementation to emulate the Tamagawa interface protocol for position sensing encoders within the ICSS module of TI Sitara AM24x/AM26x/AM64x SOCs.
  • Experienced in creating ARM CORTEX R5F applications, designing driver API layers, and developing PRU firmware.
  • Increased efficiency and reduced costs by implementing programmable IPs in place of FPGAs.
  • Improved Scalability in terms of baud rates from 2.5 Mbps to 16 Mbps, single to multi-channel (6 channels per ICSS module) support, ability to support all custom UART protocol with variety of frame formats.
  • Implemented GUI interface for motor position sensing by utilizing multiple Tamagawa encoders.
  • Gained expertise in various aspects including reading board schematics, debugging techniques, hardware setup creation, firmware design as well as driver and application architecture development
