Why Choose Our Firmware Engineering?

At PMT Electronics, our core focus and deepest expertise lie in developing advanced control algorithms for Power Electronics and Motor Control. We bridge the gap between high-power hardware and intelligent software to deliver maximum efficiency and precision.

We strictly adhere to rigorous automotive and industrial coding standards, primarily MISRA-C, ensuring that our firmware is not only high-performing but also mathematically verifiable and unconditionally safe for mission-critical applications.

  • Real-Time Performance: Deterministic execution using FreeRTOS, Zephyr, or custom schedulers.
  • Secure Boot & OTA: Cryptographically signed firmware updates over the air.
  • Algorithm Design: Field-Oriented Control (FOC), DSP, and PID control loops.
  • Low-Power Optimization: Extending battery life through advanced sleep state management.

Our Software Expertise

Bare-Metal Programming

Highly optimized, interrupt-driven C/C++ programming without OS overhead for maximum performance and minimum footprint on resource-constrained MCUs.

RTOS Integration

Implementation of FreeRTOS, Zephyr, and ThreadX for complex, multi-threaded applications requiring deterministic task scheduling and IPC.

Motor Control Algorithms

Advanced sensorless and sensored Field-Oriented Control (FOC) algorithms for BLDC, PMSM, and induction motors.

IoT & Connectivity

Integration of BLE, Wi-Fi, LoRa, and cellular stacks. Implementing secure cloud connectivity using MQTT, CoAP, and TLS/SSL encryption.

Secure OTA Updates

Developing custom bootloaders with dual-bank flash support, cryptographic signature verification, and fail-safe recovery mechanisms.

Embedded Linux

Custom Yocto/Buildroot image creation, device tree configuration, and kernel driver development for high-end SoCs and edge processors.
