(2022-11)

• Configured and used ADC in both polling and interrupt modes for sensor data acquisition.
• Implemented hardware timers for delays, periodic task execution, and timeout management.
• Developed interrupt-based firmware for peripherals such as UART, ADC, and external inputs.
• Implemented circular queue (ring buffer) for UART to receive data to ensure loss-free and continuous data handling.
• Designed interrupt-driven UART communication with buffered data processing.
• Developed bare-metal firmware for STM32, STM8S, and PIC microcontrollers using C.
• Designed and implemented low-level drivers through direct register configuration.
• Configured microcontroller peripherals using both register-level programming and HAL/SPL libraries.
• Implemented and debugged serial communication protocols including UART, I2C (hardware & bit-banged), and SPI.
• Integrated external modules such as RTC, thermal printers, PSR, and NIBP modules.
• Performed firmware and hardware debugging using SWD, SWIM, and oscilloscope-based signal analysis.
• Support board bring-up, testing, and validation in coordination with hardware teams.
