ESP32-P4 & C6 Tuto 3 : Piloter un Moteur Pas à Pas et Régler TH/TB en Temps Réel

In this new tutorial, we'll create a fully interactive test bench for stepper motors, controlled entirely from a web page hosted on an ESP32-P4. Contents: 00:00 Project Overview 04:12 Software Demonstration: Signal Regularity at the Heart of ESP32-P4 Control 08:24 Preparing the ESP32-P4 Board: Key Settings Before Wiring 10:52 Wiring Diagram Analysis and Interpretation 13:22 Studying the 4 Pillars of Flawless Motor Control 28:42 Technical Specifications The principle is simple: using a web browser (computer, tablet, or smartphone), you'll be able to take complete control of the motor without any external software. On this web interface, we will learn how to: Enable or disable the driver using the ENABLE command, which allows the motor to be released or its holding torque restored, Start and stop the generation of STEP pulses in real time, Instantly change the direction of rotation of the motor (forward/reverse), And above all, dynamically adjust the shape of the signal: the high time (TH) and low time (TB) of the pulse, directly from interactive sliders. You will see live how these settings influence the pulse frequency, the rotation speed, and the smoothness of the movement. This is an excellent way to concretely visualize the role of the duty cycle in a motor signal, a true immersion in the world of real-time control. Under the Technical Hood Our system is based on the JC-ESP32P4-M3 board, a dual-processor module: the ESP32-P4 dedicated to motor control and precise pulse calculation, the ESP32-C6 reserved for Wi-Fi communication and hosting the web page. This architecture allows for microsecond precision on the STEP signal, without any jitter, while maintaining a connection. The secret lies in the esp_timer.h library, which makes the P4 a true electronic metronome, independent of the rest of the program. Thanks to this approach, the board generates a perfectly stable signal, even under heavy Wi-Fi or web browser load. 🧠What you will learn: How to control a stepper motor via an ESP32 web page How to adjust the frequency and duty cycle of a STEP signal How to stabilize pulse generation to the microsecond level How to decouple Wi-Fi from motor control for professional operation Hardware used: JC-ESP32P4-M3 Development Board https://fr.aliexpress.com/item/100500...
