NuttX

This article extends the NuttX motor control system with inertial measurement unit (IMU) sensor integration for vibration measurement and wireless data streaming capabilities using the ESP32-C6 Wi-Fi connectivity.

In this article, we explore a simplified ESP32 boot process using single-image binaries to speed up build and flash times — ideal for development workflows. This approach sacrifices features like OTA updates but enables faster iteration.

This article demonstrates how to implement motor control and speed sensing on an ESP32-C6 using NuttX RTOS. It covers setting up MCPWM for motor control, ADC for potentiometer reading, and quadrature encoder for speed measurement. The implementation showcases NuttX’s real-time capabilities through a practical example using common peripherals and sensors.
