3. testing/

This directory contains the experimental codes tested for individual components of the static firing system. These are modular and can be combined as needed for use on the ground or testbed sides.

Subdirectories:

1. Load Cell/

   • Contains code for interfacing with a pancake load cell using:
     • TP-400 Mini Weight Indicator
     • HX711 ADC Converter

2. MKR Zero/

   • Experimental versions of the codes implemented on an Arduino MKRZero microcontroller for evaluating a potential upgrade from the Arduino UNO.

3. MLH Pressure Transducer/

   • Code for acquiring pressure data from the MLH Pressure Transducer using bare-metal (register-level) programming

4. Plotter/

   • Includes scripts and tools for visualizing sensor data and current state of the system, aiding in system evaluation.

5. RYLR/

   • Firmware for the LoRa RYLR998 module, including:
     • Transmission code and Reception code for testing
     • Transceiver Code for 2-way telemetry
