My team created a data logger for tracking customer behavior during tool testing campaigns. I conceptualized and executed the first iteration of the electrical circuit design and developed efficient code for the MSP430-based data logger.
I was responsible for the first iteration of the MSP-340 PCB. The design included a binary voltage sensor, an RTC clock, and a TF card reader (micro SD reader/writer).
The concept behind the circuit was to use a diode to prevent voltage from returning to the voltage regulator when the user released the switch. A capacitor on the far right would charge while the tool was on. The stored charge would allow the system to prepare the data and save it to the micro SD card. The code was optimized to prepare and save data to the micro SD card in no more than 0.019456 seconds.
I coded the system using a modular approach, creating separate handlers for each system: RTC, Micro SD reader/writer, and voltage sensing. The main code is abstracted, allowing components to be swapped out as needed without modifying the main code.
I manufactured multiple data loggers for delivery to the sponsor. Additionally, I contributed to the creation of a user-friendly manual and delivered multiple high-performing data loggers to the sponsor.
