OSes and integration ESP-IDF (OS based on FreeRTOS) - https://github.com/esp-rs/esp-idf-hal (full feature) no_std a.k.a. bare metal with Rust - https://github.com/esp-rs/esp-hal (minimalistic) Zephyr - https://zephyrproject.org/ - EDC22 Day 1 Talk 10: Applications of Asymmetric Multiprocessing with ESP32 Devices - including Rust on one core - https://youtu.be/oble9ObAqxM NuttX - https://nuttx.apache.org/ (as app, Linux-like OS) SVD files: https://github.com/espressif/svd
- 4. Further languages and frameworks Arduino - Maker choice - warning: limitation on production due to licenses! VM based: - CircuitPython and MicroPython - Python-like language - Toit - Toit language - Nanoframework - C# language - downside: bigger VM - upside: more robust, comes with OTA and monitoring
