Ascent R2 Hardware Validation Suite

This repository contains the hardware validation and calibration suite for the Ascent R2 flight computer. The suite is designed to perform comprehensive testing of newly assembled Ascent R2 PCBs to ensure proper hardware functionality and sensor calibration.

Purpose

The validation suite serves four primary purposes:

1. Hardware Verification

   • Validates all components on a freshly soldered Ascent R2 PCB
   • Tests communication interfaces (I2C, SPI)
   • Verifies sensor initialization and basic functionality
   • Checks pyrotechnic channels and safety systems
   • Tests power management and voltage regulation

2. Software Library Validation

   • Verifies the functionality of all custom driver libraries
   • Tests sensor data acquisition and processing
   • Validates communication protocols and data handling
   • Ensures proper integration between different components

3. Sensor Calibration

   • Performs comprehensive sensor calibration procedures
   • Corrects for:
     • Bias offsets
     • Scale factor errors
     • Non-orthogonality in multi-axis sensors
   • Generates calibration parameters for flight software

4. Hardware Serialization

   • Generates unique UUID for each Ascent R2 PCB
   • Records detailed hardware manifest including:
     • Individual sensor serial numbers and characteristics
     • Radio transmitter identifiers
     • Active IC specifications and versions
   • Stores serialization data in write-protected flash memory block
   • Provides permanent hardware reference for flight/ground station firmware
   • Enables hardware-specific configuration and calibration loading
