Storage

[jtguggedal]

This pull request introduces a new, configurable storage module for the application, supporting both RAM and internal flash backends. It adds Kconfig options for fine-grained control, implements a modular backend interface, and provides a RAM ring buffer backend. The changes also define a flexible system for registering and handling multiple data types for storage, and introduce new shell commands for interacting with the storage module.

New Storage Module Implementation

• Added a new storage module with configurable Kconfig options, allowing selection between RAM and internal flash backends, control of memory usage, FIFO settings, and shell command support. (Kconfig.storage [1] CMakeLists.txt [2]
• Implemented a backend interface in storage_backend.h, enabling easy addition of new storage backends (RAM, flash, etc.) via a unified API. (storage_backend.h app/src/modules/storage/storage_backend.hR1-R73)
• Developed a RAM ring buffer backend for data storage, supporting multiple data types, automatic overwriting of old data, and efficient memory use. (backends/ram_ring_buffer_backend.c app/src/modules/storage/backends/ram_ring_buffer_backend.cR1-R365)

Data Type Registration and Handling

• Introduced a flexible system for registering and processing multiple storage data types, with helper macros and functions for extracting and checking data from different modules (power, environmental, location). (storage_data_types.c app/src/modules/storage/storage_data_types.cR1-R86)

Storage Module API and Messaging

• Defined the main storage module API and message structures, including support for various storage operations (buffering, flushing, FIFO, stats) and Zbus channel integration. (storage.h app/src/modules/storage/storage.hR1-R122)

Workflow and Build System Updates

• Updated the build system and workflow to include the new storage module and its configuration, and made a minor change to the SonarCloud workflow to adjust sanitizer usage. (CMakeLists.txt [1] .github/workflows/sonarcloud.yml [2]

Pull Request Overview

This pull request introduces a comprehensive new storage module for the Asset Tracker Template, providing flexible data storage capabilities with both RAM and internal flash backends. The module implements a state machine-based architecture supporting pass-through mode for real-time data forwarding and buffer mode for persistent storage, along with a batch interface for safe concurrent data access.

• Adds a configurable storage module with Kconfig options for backend selection, memory limits, and operational modes
• Implements a modular backend interface with RAM ring buffer backend for efficient FIFO storage
• Introduces a flexible data type registration system that automatically discovers and handles multiple data types from enabled modules
