@markoa7

Hi there, I’ve reviewed your STM32 solar tracker pilot and I’m confident I can deliver rock-solid actuator control and tight CAN integration without disturbing your existing sensor data paths. My plan is to implement robust PID-based position control for the linear actuators, add reliable end-stop and stall handling, and layer safety interlocks into the motion loop. I’ll package position reports, health data, and fault codes into your CAN DB frames, while keeping sensor reads refreshed with minimal latency. Deliverables will be a cleaned CubeIDE project, a configurable header, thorough in-code docs, and a remote bench demonstration using your test setup. What is the preferred initial motion profile (speed, acceleration) for the first field test, and are there any environment constraints to consider? Best regards, Marko Aleksic

Hello, I am an experienced STM32 embedded-systems engineer with strong background in actuator control, CAN integration, and industrial-grade firmware design. I will implement precise linear-actuator position control with robust end-stop detection, stall monitoring, safety interlocks, and smooth motion profiling tailored to your mechanical specs. Using STM32CubeIDE and HAL (with optional FreeRTOS), I will structure deterministic control loops and clean abstraction layers for maintainable, field-ready code. CAN communication will strictly follow your DBC, ensuring reliable real-time command handling, structured health reporting, and fault management. All parameters such as stroke limits, velocity caps, watchdog timing, and safety thresholds will be configurable through a dedicated header without altering core logic. You will receive fully documented source code, a clean Git workflow, a concise markdown build guide, and a live VPN-based bench demonstration with simulated fault handling. I am confident in delivering a stable pilot-ready firmware foundation and supporting long-term scaling to multi-axis arrays; regards engr Muhammad Usman

Having worked extensively in industrial automation, I can confidently say that this project aligns perfectly with my skillset. Not only have I developed firmwares for various control systems but I've also successfully implemented complex motion control algorithms much like what's required for your solar tracking system. My proficiency in STM32 (HAL/CubeMX), FreeRTOS, and CAN stacks, combined with my experience in real-time systems will be vital in ensuring the precise and reliable actuator control you're looking to achieve. Furthermore, my established Git workflow and strong documentation practices will ensure transparency throughout the development process. I understand the value of a dynamic system that allows for easy reconfiguration without compromising core logic. With this in mind, I would develop configuration headers that make it straightforward for you to adjust stroke, speed limits, and watchdog timings without having to recompile the core firmware.
