Invert Sensor Logic & Optimize Code

@engrusmanfaiz

I will correct the infrared sensor logic by cleanly mapping its active-LOW behavior into a stable boolean state within your existing Portenta C33 sketch. The updated logic will be directly linked to your TCP command structure to ensure precise LED fan control. I will maintain your current code style while improving readability and minimizing unnecessary changes. After validation, I will refactor affected sections to enhance structure and long-term stability. Focus will be placed on reliable networking behavior and fault tolerance for continuous operation. The final sketch will compile cleanly without warnings and follow best embedded coding practices. Testing will be iterative—based on your hardware feedback, I will quickly refine any mismatches. All changes will be documented clearly for traceability and future maintenance. Ready to start immediately and deliver fast, stable results.

Hi, I am an embedded systems engineer with 8+ years of experience in Arduino and C++ development, including 5+ projects on the Portenta family. I have implemented reliable sensor-driven systems, achieving up to 99.8% uptime on long-running IoT devices, and optimized networking code to reduce latency by 30%. Approach: ✅ I will first invert the infrared sensor logic in the existing sketch and map it accurately to the supplied TCP commands. ✅ I will review the sketch structure and remove any redundant code or timing conflicts affected by the logic change. ✅ I will implement stability enhancements, including improved fault handling, memory checks, and non-blocking network operations. ✅ I will compile and test the sketch to ensure zero warnings, long-term reliability, and clean maintainability. Questions: ✅ Can you confirm the exact TCP command format and any required acknowledgment for the LED fan? ✅ Are there any timing constraints for sensor detection versus fan activation? ✅ Should I maintain all current debug prints or remove/optimize them for long-term operation? ✅ Are there any additional peripherals or network tasks running simultaneously that might affect stability? Best, Yaroslav

Hello, the sensor interface or signal reverse part is quite straightforward. I can provide you with documentation and software at whatever level of clarity you prefer. As I understand, based on your algorithm, you want to send specific TCP commands. If you have time, we can complete this project within the day.

Hi there, I’m an embedded systems engineer with 9+ years of experience in Arduino/Portenta platforms, C++, and TCP/IP control systems. I’ve worked on real-time sensor-driven logic with network-triggered actions, so this is a clean, fast turnaround task. Approach - Reverse-map the IR sensor logic (HIGH→idle, LOW→trigger) cleanly into your existing sketch - Link detection events to your TCP command set for LED fan control (non-blocking, reliable) - Refactor affected sections to keep the code structured, readable, and maintainable - Add debouncing, edge detection, and fault handling for stable long-term operation - Ensure clean compile with zero warnings Workflow • I update the code → you flash/test → I refine immediately based on feedback • Fast iteration to complete within your short timeline Deliverables • Updated sketch with correct sensor logic + TCP mapping • Stability-optimized revision (non-blocking, robust) • Clear changelog of all modifications I focus on clean embedded logic and reliable runtime behavior, ensuring your system runs continuously without glitches. Ready to start immediately and iterate with you in real time. Best regard

I am an experienced embedded systems developer with strong hands-on expertise in Arduino-based development and C++ firmware design. Previously, I have worked on multiple Arduino and IoT-based systems involving sensor-triggered actions. Based on this experience, I can quickly update your Portenta C33 sketch by correctly inverting the IR sensor logic and mapping it to your TCP commands for the LED fan. I will also refine the code for better structure, stability, and warning-free compilation. I’m comfortable with rapid feedback cycles and can iterate quickly based on your testing results.

I work extensively with Arduino platforms and have strong C++ skills — the Portenta C33 and its networking stack are familiar ground. Inverting active-LOW sensor logic and mapping it cleanly to TCP command dispatch is a straightforward fix, and I can turn it around fast. Rather than scattering raw digitalRead inversions through the sketch, I’ll wrap the sensor read in a clean helper so the rest of the code reads naturally — “detected” always means detected, regardless of sensor polarity. That makes the TCP command mapping clean, readable, and easy to maintain going forward. For the stability pass I’ll review the networking section for blocking calls, add a watchdog or reconnect guard if missing, eliminate blocking delays from the main loop, and deliver a sketch that compiles warning-free and runs reliably for long periods. Deliverables: updated sketch, clean changelog, fast revision rounds today and tomorrow as you test on hardware. Send over the current sketch and TCP command list and I’ll get started immediately.
