Unlock the full potential of your ESP32 motor projects by switching from LEDC to the MCPWM peripheral. While LEDC is fine for general PWM tasks, it struggles with motors due to coarse resolution, edge-aligned output, and less efficient torque delivery. MCPWM, on the other hand, is designed in silicon specifically for motor control, offering complementary outputs, dead time insertion, higher resolution, and real hardware fault handling.

In this video, you’ll see side-by-side LEDC vs MCPWM tests, including sweep and rotation demos that highlight smoother torque, more usable range, and better efficiency at low duty cycles. We’ll then walk through integrating the ESP32 MCPWM library into both Arduino IDE and PlatformIO, and show how it fits within a FreeRTOS framework for scalable projects.

You’ll learn:
✅ Hardware wiring with IBT-2/BTS7960 driver and buck converter
✅ Sweep test results (LEDC stalls vs MCPWM smooth operation)
✅ Rotation test showing torque consistency and stability
✅ RTOS integration for advanced motor control

Perfect for DC motors, BLDC, H-bridges, and servo projects in robotics, Power Wheels mods, or IoT devices.
