FIR Filter, Bluetooth, CICD, Design Patterns

The Sensor app has a wide range of features and capabilities, including the use of various design patterns to ensure efficient operation. It also utilizes the monotonic CPU clock and FIR filter for accurate data capture and export. Additionally, the app can synchronize and control a GoPro camera via Bluetooth and Wi-Fi. App updates were continuously integrated and continuously deployed (CICD) along with automated UI and unit testing in the process. Furthermore, I automated documentation generation via DocC. Lastly, I packaged the technology into an SDK for other developers to consume.

Highlights

• Design patterns: MVVM, Mediator, Delegate, and State patterns.
• Used the monotonic CPU clock to sync sensor samples and prevent anomalies that result when using wall clock time.
• Energy-efficient inertial sensor data capture at 100Hz.
• Decimate and export sensor data via FIR filter.
• Bluetooth and Wi-Fi synchronization and control with GoPro camera.
• Continuous Integration and Continuous Deployment (CICD).
• Automated UI and unit testing.
• Automated documentation via DocC.
• Packaged the technology into a reusable SDK.
