SD Card Performance in CircuitPython #CircuitPython #AdafruitLearningSystem @Adafruit

7 hours 14 minutes ago
This guide benchmarks SD card performance in CircuitPython across a range of boards, card tiers, and filesystems. The findings are straightforward: SDIO for bulk transfers, SPI for fast small writes. For max performance, pair a card over 32 GB (A2/U3 rated) with an exFAT filesystem. Read more at SD Card Performance in CircuitPython

AkiraOS: A WebAssembly runtime for microcontrollers

16 hours 58 minutes ago
AkiraOS is Artur Founder’s Zephyr-based embedded OS that runs sandboxed WebAssembly applications on microcontrollers. The core idea: separate the OS from the application. The firmware stays stable. Apps are .wasm binaries — isolated, portable, and deployable over-the-air without touching the OS. Your App (C/C++/Python) → compile → app.wasm → SecureDeploy → runs on device OS unchanged Why this […]

The Quiet Numbers Station: Decoding nineteen years of GPS cryptography

17 hours 27 minutes ago
The Global Positioning System (GPS) relies on its primary L1 frequency to broadcast precise timing and orbital data, allowing receivers on Earth to calculate their exact location. Because the L1 C/A signal transmits at just fifty bits per second, every bit of this navigation data must earn its place. Yet, within this highly constrained signal, […]
