STM32 Jobs

i am looking for an engineer in power electronic who has some experience with F280039c or stm32g474 or esp32 to make a spwm for full h bridge inverter ( pedagogic )

I am building a battery-powered edge node around the STM32WL (LoRa-E5 module) that must sit in the field for years on a single 5 000 mAh cell. To reach that target I need both the hardware design and the accompanying firmware created with an obsessive focus on nano-amp sleep currents and efficient duty-cycling. Core capabilities • Data logging to internal flash or external EEPROM so records are retained between wake-ups. • LoRa communication only; no Bluetooth or Wi-Fi. The node will periodically wake, send an uplink, accept a downlink if present, and return to deep sleep. • Simple sensor block: one digital interrupt input (e.g., reed switch/pulse counter) plus one digital output that can drive an external load for a short, timed burst. Hardware scope – Compl...

I’m looking for an experienced engineer who can take my custom-built hardware and make it work seamlessly within a larger system. The heart of the job is hands-on hardware integration—not general project management—so I need someone who is comfortable troubleshooting boards, refining firmware, and confirming that every physical connection and signal behaves as intended. Key goals • Map out the integration plan for the custom boards, interfaces, and peripherals I already have on hand. • Develop or refine any required low-level firmware so the hardware communicates reliably with the host system. • Validate the full signal chain with bench testing, basic stress tests, and a succinct report of results. What I’ll provide – Schematics, compone...

I’m outfitting an ArduCopter that runs 6-cell Li-ion packs and need a purpose-built Battery Management System. The board and firmware must continuously monitor pack health, actively balance the cells and speak Mavlink over CAN so the flight controller sees accurate live data. Core functions • Real-time battery monitoring with voltage, current and temperature reporting for every cell and for the full pack • Automatic cell-to-cell balancing to maximise capacity and cycle life • Safety layer that disconnects or limits power on over-charge, over-discharge or short-circuit events • Mavlink-over-CAN telemetry, using the standard ArduCopter battery status messages so Mission Planner and QGroundControl display everything without custom plugins What I expect as d...

I have a working Arduino Nano sketch that I now need running on an STM32. The project must be opened, built and flashed entirely inside STM32CubeIDE, so please base every file and configuration step on that toolchain. Key points you will handle • Rewrite the existing sketch for the chosen STM32 device, configuring clocks, GPIO, interrupts and peripherals exactly as needed. • Replace the current Arduino-style calls with HAL-based code generated in CubeMX, keeping the program logic identical. • The original sketch drives an OLED via a third-party library; the same display has to work on STM32, so include whatever open-source driver (U8g2, SSD1306 HAL port, etc.) you feel is most stable. • Alongside the source, provide a short step-by-step guide that shows how t...

I’m building a single-phase grid-tie solar inverter around the STM32F103 and need both the hardware completed and the firmware written. The control board must handle MPPT, keep perfect grid synchronization, and expose real-time data for remote monitoring. Firmware requirements • Implement a reliable MPPT algorithm suited to PV strings. • Keep the inverter phase-locked to the utility, injecting power with a clean sinusoid and rapid anti-islanding response. • Expose operating metrics (voltage, current, power, temperature, fault states) through Modbus, CAN bus, and Ethernet. Hardware requirements • Schematic and PCB layout for the STM32F103 control board, opto-isolated gate-drive interfaces, sensing circuitry, surge protection, and communication ports. ...
