This system was designed to manage three-phase AC motors through a Teco S310 inverter, providing precise speed control, flexible operation, and industrial-grade safety. It features a capacitive touchscreen interface alongside physical push-buttons, real-time monitoring of sensors, and hardware protection mechanisms. Memory expansion with OSPI and QSPI enables a large application footprint and persistent parameter storage, while an RTC ensures reliable timekeeping.

• STM32H7 + FreeRTOS – Real-time firmware handling motor control, multi-tasking, and system logic.
• Teco S310 Inverter Communication – RS485/Modbus RTU link for precise motor frequency control.
• TouchGFX GUI – A 4.3" capacitive touchscreen interface designed for intuitive operation.
• Multi-Input Control – Supports both touchscreen and three dedicated push-buttons.
• OSPI Flash – Runs a large 7 MB firmware image efficiently.
• QSPI Flash – Stores and retrieves persistent parameters (e.g., wake-up time).
• RTC Integration – Timekeeping and scheduling embedded into system logic.
• Inductive Sensor Feedback – Ensures gear alignment in a specific direction and verifies sensor health.
• Micro-Switch Door Control – Stops the motor immediately if the access door is opened mid-operation.
• Emergency Stop Button – Hardware-level override to halt the system under any condition.
• Inverter State Detection – Monitors ON/OFF state of the Teco S310 for safe operation.
• Motor Brake Control – Relay-based activation/deactivation of motor braking when required.
• Safety & Feedback – Buzzer alerts, indicator lights, and fault detection for robust operation.
• From Scratch Development – Firmware, UI, and hardware integration fully custom-designed.
