KINDLY READ THROUGH MY PROPOSAL STM32 THIS IS WHAT I WILL DO - Write clean, interrupt-driven firmware in C (STM32CubeIDE / HAL) for STM32L010F4P6 - 5-step PWM fan control (0/25/50/75/100 %) using TIMx PWM channels, button press cycles through levels with debounce - RGB LED control: simple state machine showing current fan speed (different colors/patterns per level) - Basic I²C communication with BQ25895: read battery voltage + charge status on demand, no fancy charging config needed - Deliver complete project folder ready to flash + quick comment on pin mapping RELEVANT EXPERIENCE - 7+ years daily STM32 work (F0/F1/F3/L0/L4/G0/G4 series mostly) - Done dozens of simple fan + LED + button control projects (server fans, enclosure cooling, portable devices) QUESTIONS (to deliver working code Day 1–2) - Which timer channels/pins are already assigned to the two PWM outputs? - Preferred LED colors per speed level (or just give me freedom)? - Button: active low/high + any pull-up already on board? - Do you want voltage shown somehow (e.g. LED blink pattern) or only read for debug? Very quick & straightforward job for me – I can usually have first version running on real hardware within 24–48 h after receiving schematic/pinout. Ready to start as soon as you share the details. Looking forward to a smooth first project and hopefully many more!

@mykolalus

***STM32*** ⭐⭐⭐⭐⭐ Senior PCB & Firmware & IoT Engineer Here! ⭐⭐⭐⭐⭐ Hello! I have checked out your project details and I am confident that I can finish your project perfectly. I can deliver clean, reliable firmware for the STM32L010F4P6 that drives two 5 V fans via PWM with five discrete speed steps, handles a push-button speed selector, controls an RGB LED, and interfaces correctly with the BQ25895 charger for battery voltage monitoring and basic status. I have hands-on experience with STM32 low-power families (L0/L4), including timer-based PWM, GPIO interrupts, debouncing, and I²C peripheral drivers for power-management ICs. For this project, I would use a simple, readable state machine for fan speed control, hardware timers for stable PWM generation, and an interrupt-driven button handler to ensure responsive operation. The RGB LED will be driven with deterministic GPIO or PWM as appropriate, and the BQ25895 will be initialized and read using a minimal, robust I²C layer. The code will be well-commented, easy to review, and tested against your real hardware. Looking forward to discussing more details. Regards, Mykola

Hello, I’m an embedded systems developer with 6+ years of experience working on STM32 microcontroller projects, and I’ve carefully reviewed your PWM fan control firmware requirements. I’ve delivered 10+ STM32-based firmware projects, including fan speed control, PWM output management, push-button input handling, and RGB LED signaling, all written in C with HAL/LL libraries. For your project, I would implement 2 PWM-controlled 5V fans with 5 discrete speed levels, a push-button interface to cycle speeds, and RGB LED control across 3 outputs, along with reading and configuring the BQ25895 battery charger for voltage monitoring. I always focus on robust, real-hardware-tested firmware with clean code and simple debugging hooks, ensuring functionality immediately on your board. In previous projects, I achieved response times under 50 ms for button-driven PWM changes and successfully integrated peripheral drivers on STM32L series chips. You will receive fully tested, ready-to-flash firmware, well-documented source code, and setup instructions for easy integration and future maintenance. I’m confident this can be completed within a few days, and I’m excited about the possibility of supporting your future STM32 projects.

***STM32*** Best STM32 PWM Fan Control & Peripheral Handling ⭐⭐⭐⭐⭐ Hi, Thanks for sharing the scope clearly. I’ve supported prototype-to-small-batch builds where STM32 firmware, peripheral control, and board testing needed careful development, integration, and verification before deployment. Your project looks very doable. The goal is simple: deliver fully functional firmware for your STM32 board, driving fans, RGB LEDs, and battery monitoring reliably. ✅ How I’ll Help You Succeed 1. Review your schematics, pin assignments, and peripheral requirements before writing code. 2. Develop clean, efficient STM32 code to control two 5V fans via PWM with 5 adjustable speed settings using your push-button interface. 3. Implement RGB LED control across 3 outputs and integrate battery voltage monitoring/charger configuration (BQ25895) as needed. I’ve delivered STM32 projects, including PWM motor/fan control, button-driven state machines, LED indicators, and power-management IC integration, all tested on real hardware. ✅ Before I start, one quick thing: Do you prefer STM32 HAL or low-level (LL) drivers for this project? If you share that, feel free to message me and we can align quickly. Best regards, Prat PCB Must Innovations

***STM32*** Hi , Thanks for posting your STM32 PWM fan control firmware project. I have experience writing code for STM32F030K6T6, STM32F103C8T6, STM32F207VET6, STM32F446RE and STM32F411RE, with RTOS support and using HAL/LL drivers. This is my proposed solution: SUMMARY: STM32CubeIDE project RTOS with threads for PWM update, button read and debounce, LED control and battery monitoring. .h/.c drivers for BQ25895. DELIVERABLES: - Source code (STM32CubeIDE project) and firmware image (.HEX, .BIN) PRICE ESTIMATE: USD 238 LEAD TIME: 3 work days BACKGROUND: 12+ years of experience in hardware design, programming in C, C++, Arduino, Python, Pytorch, NumPy Please check my portfolio with examples of past jobs. Hoping it will meet your requirements. Looking forward to your reply. --- Best Regards, Gonzalo Perez, EE

@yaroslavmark

✅ Okay, I got what you want exactly. I am an embedded systems firmware engineer with over 10 years of experience, providing STM32 bare-metal and HAL-based development, PWM motor control, GPIO, and peripheral integration. In my opinion, the cleanest solution is a lightweight STM32CubeMX/HAL project where timers generate stable PWM for both fans, with debounced button input cycling through five duty-cycle presets and clear RGB LED state feedback. I would also keep the firmware simple and deterministic so it’s easy for you to test and extend later. This project is very similar to my previous work, including an STM32L0-based battery-powered controller where I implemented dual PWM outputs (25–80% duty steps), button state machines, and status LEDs, plus I²C communication to read battery voltage from a TI charger IC and report it over debug logs. ✅ So, I will divide your project like following: ⚡ Review schematics, pin mapping, and clock configuration for STM32L010 ⚡ Implement PWM fan control with five speed levels and push-button handling ⚡ Configure RGB LED outputs and integrate basic BQ25895 voltage reading ⚡ Hardware testing support, debugging, and final cleanup Via private chatting or meeting, I will provide the creative idea and solid technical solution for your project, and I’d like to discuss the budget and timeline in detail. Best regards. Yaroslav
