Dual-Core Real-Time Industrial PID Controller
Dual-Core Real-Time Industrial PID Controller — Master Hard Real-Time Control on Arduino Portenta H7
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
The Cortex-M7 core on the Arduino Portenta H7 becomes your dedicated motion engine, running a closed-loop PID algorithm at a relentless 10kHz update rate to command a NEMA 23 stepper motor with encoder feedback. Simultaneously, the M4 core manages the vibrant TFT HMI display, serial communication, and system health monitoring — exactly as a genuine PLC separates time-critical control from user interface tasks. This isn’t just a learning exercise; it’s a hardware-reference design for real industrial motion control.
What You'll Build
You’ll assemble and program a DIN-rail mounted dual-core controller that accepts encoder position feedback and drives a powerful 2Nm NEMA 23 motor with sub-millisecond deterministic response. The M7 core owns the entire PID loop — no touch-screen lag, no UART interrupt jitter, just pure 10kHz precision. The M4 core serves a fast, responsive ILI9341 display showing live motor speed, position error, and tuning parameters while talking to external devices over UART or USB.
What You'll Learn
- Implementing a real-time PID control loop on an Arm Cortex-M7 core at 10kHz update rates
- Structuring dual-core applications: critical M7 tasks vs. non-critical M4 display and communication
- Interfacing a DM542 stepper driver with encoder feedback (LM393) for true closed-loop positioning
- Industrial wiring practices — EMI filtering, buck converter power distribution, and DIN-rail mounting

Who This Kit Is For
Final‑year B.Tech ECE/EEE students building advanced control system capstones, Smart India Hackathon teams needing a production‑grade real‑time controller, and embedded developers at IITs, NITs, VIT, or BITS Pilani who want to move from single‑core Arduino sketches to certified dual‑core industrial designs. If you’ve tinkered with stepper motors before and are ready to tackle deterministic loop rates, this kit is your next step.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code on the box to access the AI build companion; it walks you through every connection and code block. If you need a human, our WhatsApp support answers within an hour.
Does this kit require me to write the PID algorithm from scratch?
You’ll implement the PID logic yourself to learn the inner workings, but the AI companion provides code templates, explains tuning strategies, and helps you adapt the loop timing to exactly 10kHz.
Can I replace the NEMA 23 with a smaller motor for a lighter load?
Yes, the DM542 driver handles smaller steppers easily. The included 2Nm motor is selected to demonstrate robust industrial control, but the closed‑loop design works with any two‑phase stepper.
Is this kit suitable for a Smart India Hackathon project?
Absolutely. The dual‑core architecture and DIN‑rail mounting make it a self‑contained, plug‑and‑play industrial control module that fits right into hackathon prototypes requiring precise motion.
M7 core runs PID loop on NEMA23 stepper at 10kHz. M4 core handles HMI display and serial comms simultaneously.
