## AI overview

A tutorial on using the NuttX real-time operating system with the Wokwi simulator. 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.
