Static-Fire

Assists in static fire testing of our solid motor.

Overview

To support static fire tests, this project streams data from the LabJack T7 and logs it to a CSV file. In the current version, it streams from two analog pins to collect load cell and pressure transducer data. The code in main.cpp adapts example code from LabJack (https://github.com/labjack/C_CPP_LJM), and the files in lib/ are modified from some header files provided by the LJM library.

Getting Started

Dependencies Required
