This is a school organization that I am a member of. - I am working on the firmware to allow for logging data from the sensors on the car to an SD card using Arm Mbed OS. - I have designed and developed an abstract Data Logger interface and a derived SD Data Logger class for specific use with an SD card. - I have written error-checking file system operation functions in C++ utilizing the SDBlockDevice and FATFileSystem APIs in Mbed OS.

May 2023 - Aug 2023
- Prototyped and developed drivers for 9 different sensors and peripherals. - Combined several of them into one system with a strain gauge, an O2 sensor, a CO2 sensor, a differential pressure sensor, an OLED display to show sensor data, and a rotary encoder for UI controls. - Developed a custom data bus for a load cell amplifier, wrote a peak detection algorithm for a heart rate sensor, and developed a calibration sequence for a strain gauge. - Learned about interrupt service routines, serial communication protocols such as UART, I2C and SPI (and how to handle running multiple instances of these at the same time), voltage dividers, debounce/low-pass filters, analog switches, pull-up and pull-down resistors, and Wheatstone bridges, as well as how to use an oscilloscope, logic analyzer, and a digital multimeter to debug hardware.

Jan 2023 - May 2023
This was my capstone project at UTD. - I developed firmware to assist with the attestation of ECUs during the secure boot process over CAN bus communication. - I created documentation regarding issues my team and I experienced during the process to help corporate improve their proprietary systems. - Added documentation to old code to make it more readable for the rest of the team. - Designed and developed the attestation protocol between two ECUs using CAN communication. - As the team leader for the project, I served as the primary means of communication between the team and our mentor and I was responsible for making sure my team was on task and had access to everything they needed. - Wrote a detailed user manual for an undocumented software tool - Wrote and debugged bare-metal C code Show less
