Hi there, I carefully read your project, and I can help write clean, compact STM32F030CCT6 firmware for your 14-switch / 13-relay control board with reliable debounce and configurable switch mapping. I’m Samuel Tshibangu, a mechatronics engineer with strong experience in STM32 firmware, GPIO control, relay systems, UART configuration, and embedded C development. I’ve worked with similar relay-control boards and non-volatile configuration logic, so I can deliver a stable, easy-to-maintain solution. I can provide the full STM32CubeIDE/Keil-ready source code, CubeMX pinout setup, momentary relay logic, UART command configuration for up to five switches, and flash-based settings storage. Feel free to send me a message. Best regards, Samuel Tshibangu

STM32 firmware with relay control and UART configuration is exactly the kind of embedded work I've done and shipped before — including a deployed cold storage monitoring system with STM32-class MCU, multi-channel relay switching, UART remote control, and non-volatile parameter storage. I have STM32 boards, relay modules, and switches in stock and will write, test, and validate the firmware on real hardware in my lab before delivery. For this project I will: • Generate the STM32F030CCT6 pinout in CubeMX — all 14 switch GPIOs and 13 relay GPIOs clearly mapped and labelled • Implement momentary hold logic for all non-configurable switches — relay energises on press, drops immediately on release, no chatter • 10–20ms software debounce on all inputs using a systick-based state machine • Configurable mapping table in flash for up to 5 switches — relay assignment and logic inversion per entry, loaded at boot, updatable over UART with a simple command set • Clean, well-commented C using HAL — buildable in STM32CubeIDE, Keil, or Makefile Delivery in 2 days: full CubeIDE project, .hex, CubeMX .ioc, and UART command reference. Once validated against the 500-cycle test, I will ship the flashed hardware to you. Do you have a preferred UART baud rate, and should the config update take effect immediately or after a reboot?

I'm a licensed professional electrical engineer with 6+ years of experience in embedded systems programming, STM32 microcontroller development, firmware design, and industrial control applications, and I will develop complete, production-ready C firmware for your STM32F030CCT6 relay control board with momentary switch logic, configurable switch mapping, and non-volatile configuration storage. I have strong expertise in STM32 firmware development using HAL and bare-metal register access, GPIO configuration and interrupt handling for switch inputs, relay control with proper timing and debouncing logic, EEPROM/Flash memory programming for non-volatile configuration storage, UART communication for configuration updates and debugging, and STM32CubeMX for pinout generation and peripheral initialization. I will develop complete firmware with STM32CubeMX project generating pinout configuration for 14 GPIO inputs (switches) and 13 GPIO outputs (relays) with clock and peripheral setup, momentary control logic for non-configurable switches where relay energizes only while switch is held and drops immediately on release, configurable switch mapping for up to five switches stored in Flash/EEPROM allowing runtime assignment to any relay or logic inversion. I can start immediately. Best Regards, Tahir Saleem

Hello, I can deliver stable STM32F030CCT6 firmware focused on deterministic relay control, low-latency switch handling, and easy future reconfiguration without touching the main application code. I’ve developed similar MCU control systems for industrial I/O, relay boards, and configurable embedded controllers where debounce reliability and non-volatile parameter storage were critical. • Approach - Develop clean embedded C firmware using STM32 HAL or lightweight register-level access depending on your preference - Configure GPIO/pinout in STM32CubeMX for easy visualization and future maintenance - Implement 14 switch inputs with robust 10–20 ms software debounce - Ensure standard switches behave as true momentary controls with immediate relay release - Store configuration safely in internal Flash EEPROM emulation - Add UART command interface for configuration/readback/testing - Support SWD-based parameter update if preferred - Include startup validation and safe defaults to avoid corrupted configs • Deliverables - Full STM32 project source code - STM32CubeMX project files - Buildable Keil / STM32CubeIDE / Makefile project - Configuration command documentation - Well-commented firmware with clear module structure - Flash memory layout documentation - Test procedure for relay/switch validation I can also structure the firmware so additional relay logic or timed behaviors can be added later without rewriting the core architecture. Regards, Nichita.

Greetings, To solve the dynamic mapping issue, we must account for the F030 lacking internal EEPROM. I will dedicate the final Flash page to emulate NVM, storing a configuration struct (Switch ID, Relay Target, Logic Invert). This loads into RAM at boot. A lightweight UART CLI will allow you to update these 1-5 configurable switches instantly without recompilation. ​To guarantee reliable execution and zero chatter for your 500-cycle test, I will avoid raw hardware interrupts (EXTI). Instead, I will build a rock-solid SysTick-driven polling state machine for 10-20ms software debouncing. ​Deliverables will include the STM32CubeMX .ioc pinout, the complete C source code (HAL-based for portability), and a ready-to-compile project layout ​I am a professional software engineer with 4+ years of corporate experience specializing in C/C++, embedded hardware control, and professional build systems (CMake). I write clean, production-grade code without overcomplicating the architecture. Let’s connect to get this started.

Hi there, I read your requirements carefully, and I can help write compact, clean C firmware for the STM32F030CCT6 relay board with proper momentary switch control, debounce handling, and configurable switch mapping. I’ll implement the logic so normal switches energize their assigned relay only while pressed, then drop immediately on release. For the configurable switches, I’ll add a lightweight non-volatile configuration table that loads at boot and can be updated through a simple UART command set, allowing switch-to-relay mapping and inverted logic without recompiling. I can also prepare the STM32CubeMX pinout/project structure, use HAL or bare-metal depending on what keeps the code clearer, and deliver buildable source code for STM32CubeIDE/Keil/Makefile. The firmware will include software debounce, clean comments, and stable relay switching to avoid chatter or missed activations during repeated cycling. Cost: ₹10,000 || Timeline: 2-3 days Payment and timeline details can be discussed further to align with your expectations. I’d be happy to help deliver reliable STM32 firmware with full source code and clear configuration support. Best regards, Oluwatobi Okedairo

Hi, I've worked with STM32F0 series extensively and your project is well within my scope — I can start immediately. Here's my approach: • HAL-based firmware (clean, portable, easy for you to maintain) • Compact debounce routine (15 ms, tunable) applied to all 14 inputs • Momentary logic: relay energises on press, drops instantly on release — no chatter • Config table for up to 5 re-mappable switches stored in the last flash page (no external EEPROM needed) • Simple UART command set: MAP, INV, SHOW, SAVE — no GUI required • Full project delivered for STM32CubeIDE + Makefile/GCC, ready to build out of the box • STM32CubeMX .ioc file included so you can visualise and tweak GPIO assignments yourself Delivery: 3–4 days. I'll test the logic in simulation before sending, and I'm available for revisions until it passes your 500-cycle test. Best regards

@YanXiaXu

I am fully proficient in STM32 application technology. I will deliver reliable code quickly, and I will also set up a test environment on my side and perform validation. I have seen the schematics you uploaded. Overall, the design is good, but for an industrial control board, there is an unacceptable flaw. It is that the quiescent state of the BC817 is undefined. According to my calculations, if you assemble 1000 boards, more than 10 of them will malfunction, and about 100 will have unclear On/Off switching behavior. I will share the specific details of the defect through a conversation.

Hi there! This project is a perfect fit for my background in embedded firmware and PCB design. I have extensive experience with the STM32 HAL and bare-metal C, and I’ve handled several similar industrial control projects involving high-density relay switching and debouncing logic. Here is my proposal for your STM32F030CCT6 board: My Technical Approach Firmware Architecture: I will use STM32CubeIDE to ensure you have a portable, buildable project. I’ll leverage the HAL for clarity while keeping the footprint compact. Logic & Debouncing: I’ll implement a timer-based debouncing routine (10–20ms) to ensure zero chatter. The 13 relays and 14 switches will be mapped efficiently via GPIO. Configurable Logic: For the 5 "special" switches, I will implement a Look-Up Table (LUT) stored in the STM32’s internal Flash (simulated EEPROM) or a dedicated sector. Serial Interface: I'll provide a lightweight UART command set (e.g., SET_MAP [Switch] [Relay] [Invert]) so you can reconfigure logic on the fly without a full reflash. Deliverables: Full source code, the .ioc (CubeMX) file for pinout visualization, and a simple README for the UART commands. Why Choose Me? I specialize in electronic hardware and firmware integration. I understand the importance of reliability in switching applications—I will ensure the code is robust enough to pass your 500-cycle stress test without watchdog triggers or missed interrupts.
