STM32G0 Sensor Firmware Development

@VTElectronics

Hi there I'm an Electronic Engineer with over 10 years experience designing embedded applications and their PCBs, you can learn more about me from my Freelancer Profile. How about a private message so I show you my previous work with advanced STM32H7s. M3 cores all running FreeRTOS Kind regards V.T.

@elect2eng

Hello, I can create the program as desired by you. I have done programming of stm32f103 for oxygen generator which has uart monitoring, button sensing, relay operation, interfacing of TFT LCD etc.................let us discuss so that we can arrive at the actual effort involved etc. Please provide a flow diagram of your sequence

Hi, Greetings! I am interested in working on your project. Could you please share the design details and technical requirements so we can discuss the project scope and key parameters in detail? I look forward to working with you. Thank you! Shivkant

Hi, I can develop the **production-ready bare-metal STM32G031G8U6 firmware** for this battery-powered sensor/control board. I have **16 years of STM32 and embedded R&D experience**, including real-time control, sensor acquisition, PWM/timers, ADC, I²C, watchdogs, low-power battery devices and industrial embedded systems. I can handle: * Interrupt-driven **~15 s state-machine demo cycle** with configurable cooldown * 3-channel **100 kHz timer/PWM generation** * TMAG5170 I²C acquisition with averaging/filtering * ADC monitoring and fault handling * STM32 STOP/STANDBY modes with timer/external wake-up * Li-Po low-battery detection and safe shutdown * Watchdog and over-current protection logic * Clean HAL/LL-based C firmware in STM32CubeIDE * Proper startup/recovery and non-blocking architecture * Production-ready commented source code * Compiled **.bin for SWD programming** * Build/setup documentation and testing support I have worked on STM32 projects involving **high-speed timers/PWM, ADC/DMA, I²C sensors, interrupt-driven state machines and low-power operation**, and can validate the firmware directly on the supplied prototype boards. I’m comfortable working under NDA and collaborating closely during bring-up and debugging. Best regards, Subhash Suman STM32 | Embedded C | RTOS/Bare-Metal | Sensors | Low Power | Firmware

Three on-board (internal) gate-driver channels at 100 kHz are the line I keep coming back to in your note. I cannot tell from that line whether the three outputs are independent PWM or a complementary set with dead time. That single answer changes which timer I set up and whether a fault has to pull all three channels down on the same update event. A one-word reply from you, independent or complementary, is enough for me to lock the PWM block.

I want to be completely transparent: I don’t have previous professional experience with this specific type of STM32 firmware project, so I don’t want to claim experience I don’t have or expect you to award me the project immediately. However, if you’re still looking for the right developer, I’d genuinely appreciate the opportunity to give it a shot. I’m willing to do the necessary self-research on the STM32G031G8U6, TMAG5170, timers/PWM, ADC, I²C, watchdogs, and low-power modes, and carefully study the datasheets and reference material before implementation. If I can demonstrate that I understand the requirements and produce working results on the prototype board, you can then decide whether to continue with me and pay based on the agreed milestones/results. I understand the technical responsibility involved and would approach it carefully rather than pretending I already have this experience.

With my experience as an embedded systems engineer, I have significant experience developing firmware for a variety of microcontrollers including STM32, which aligns well with the requirements of your project. Notably, I've worked extensively with STM32CubeIDE and the HAL/LL libraries - crucial to your project's requirement to run bare-metal in C. You mentioned specific needs like timer management, ADC sampling and I²C interfacing, all of which I’m proficient in. Low-power design is another area I specialize in. Given that this project involves working with a small, battery-powered board, my deep understanding of power-saving modes, like STOP or STANDBY, will be invaluable. Additionally, I have a lot of experience with battery management systems for Li-Po batteries. I approach each project with strong attention to detail and a commitment to delivering well-structured code with clear documentation; an attribute that I believe sets me apart. My punctuality aligns exactly with your need to move quickly; once we sign the NDA and agree on milestones we can hit the ground running. Moreover, my cross-functional skills in PCB design further make sure there are no gaps throughout the product development process. Should you choose me for this task, I commit to providing you not just a working firmware, but a polished product that meets all your expectations

Hi, I’m very interested in this project. I’m an Embedded Systems & Firmware Engineer with around 10 years of professional experience developing C/C++ firmware for ARM-based microcontrollers, including bare-metal systems. This project is closely aligned with my background: interrupt-driven state machines, timers/PWM, ADC, I2C, watchdogs, fault handling, low-level peripheral control and hardware/firmware integration. I’m comfortable working directly with MCU peripherals and producing structured, maintainable production firmware rather than prototype-level code. I can work with STM32CubeIDE and HAL/LL and provide the complete source code, reproducible build instructions and the final .bin for SWD flashing. For the low-power implementation, I would structure the firmware around interrupts/events, keeping active time to a minimum and using STOP/STANDBY modes with timer/external wake-up as required. I’d be happy to review the schematic under NDA and confirm the architecture, milestones and fixed-price quote before starting.
