It explains Wokwi's advantages and limitations, compares it with QEMU, and describes compiling NuttX locally before simulating the output on supported ESP32 Xtensa- and RISC-V-based devices. ### Source excerpt In this article, we will examine how the NuttX real-time operating system (RTOS) can be used on the Wokwi simulator, what adjustments need to be made on the NuttX side for this and what advantages the Wokwi simulator offers. Note! Note: Reviewing this article together with NuttX on an emulated ESP32 using QEMU article will help the user to distinguish between the two solutions and to determine the most suitable solution for the needs. ## Rust on Espressif chips -- 18-10-2021 DevFeed: [Rust on Espressif chips -- 18-10-2021]() Original publisher: [Read original article]() Author: John Lee Published: 2021-10-17T00:00:00Z Content type: article Language: en Sources: [Blog on Developer Portal]() Topics: [Espressif](), [Rust](), [ESP-IDF](), [Compiler](), [RISC-V](), [toolchain](), [Documentation](), [GitHub]() Tags: [blog](), [documentation](), [esp-idf](), [esp32](), [esp32c3](), [espressif](), [github](), [llvm](), [rust](), [toolchain](), [xtensa]() ### AI overview This article updates the Rust effort for Espressif chips.
