The development team at Arduino has this week introduced two new and exciting Arduino storage libraries in the form of Arduino_POSIXStorage and Arduino_UnifiedStorage. These additions are a big deal for anyone working on Arduino projects because they make handling data and storing information a lot easier. In simple terms, these libraries are tools that help developers manage and organize data in their projects without getting bogged down in complex details. Let’s dive into what these new tools bring to the table.
“The Arduino_POSIXStorage Library complements the POSIX storage functions already included in the Renesas core and the Arduino_USBHostMbed5 library, and makes them available to sketches.”
Have you ever wished for a simpler way to handle data and files in your Arduino projects? Your wish has been granted with Arduino_POSIXStorage. This library is a boon, especially for those familiar with the POSIX standard, a cornerstone of file system functions in many operating systems like Linux and macOS. Even if you’re new to POSIX, Arduino_POSIXStorage is designed to be intuitive and user-friendly.
Key Features of Arduino_POSIXStorage:
- Ease of Storage Access: Managing SD cards and USB storage is now straightforward, eliminating the need to grapple with complex storage operations.
- Flexible File System Choices: Choose between FAT32 or LittleFS, tailoring the file system to your project’s needs.
- Hotplug Support: Enjoy the convenience of detecting and managing USB mass storage devices seamlessly.
“The Arduino_UnifiedStorage library provides a unified interface to access different types of storage, including internal storage, SD cards, and USB mass storage devices. It simplifies the handling of files and directories across multiple storage mediums on Portenta, Opta, and some Nicla boards.”
Building on the foundation of Arduino_POSIXStorage, Arduino_UnifiedStorage further demystifies data and file management. This library is perfect for those seeking an approachable API in the familiar Arduino style. Other articles we have written that you may find of interest on the subject of Arduino :

- Effortless File Handling: Navigate files easily and check available data, simplifying file management.
- Robust File and Folder Actions: Confidently rename, delete, copy, and paste files and folders.
- Smooth Cross-Medium Data Transfer: Transfer data between different storage types with control over overwriting.
- Advanced File Navigation: Navigate through folder structures with ease.
- Partition Support: Work with multiple partitions on internal QSPI storage, with the option to re-partition according to your needs.
How These Libraries Simplify Projects
Let’s delve into some practical applications of these libraries:
- Automated Data Backup for Remote Monitoring Systems: For projects like agricultural monitoring or weather stations, these libraries can automate data backup routines, safeguarding data against loss due to power outages or equipment failures.
- Rapid Firmware Updates for IoT Devices: Update IoT device firmware efficiently, even in situations where Over-the-Air updates are not feasible. This ensures devices are always up-to-date with the latest software, enhancing security and functionality.
- Data Collection and Machine Learning Model Training: Collect and manage sensor data in smart environments to train machine learning models. This facilitates the development of predictive maintenance algorithms, anomaly detection systems, or smart automation routines.
Both libraries come equipped with practical examples, catering to real-life scenarios like data logging and storage backup. They have been thoroughly tested across various devices, ensuring reliability and performance.
Compatibility and Getting Started
The libraries currently support Arduino Portenta H7, Arduino Portenta C33, Arduino Opta, and Arduino Portenta Machine Control, with plans to extend support to more boards.
To get started, you can download these libraries through the Arduino IDE’s library manager or directly from their respective GitHub repositories for Arduino_POSIXStorage and Arduino_UnifiedStorage . Remember to check out the API documentation in the “docs” folder of each repository for more detailed guidance.
