I have an STM32 board that must run in USB-host mode and simply read incoming text from a sensor that enumerates as a CDC-ACM device. No parsing, maths, or storage is required—just establish the host stack, open the virtual COM port, and make the raw text stream available so I can verify it over UART or a debug console. You can start from STM32CubeMX/HAL or bare-metal, as long as the firmware cleanly enumerates any standard CDC device and continuously forwards the characters it receives. A minimal example project that compiles in STM32CubeIDE. USB device is powred using external power. only D+, D- and GND are common Deliverables • STM32CubeIDE project files with USB host CDC class enabled • Non-blocking loop that echoes all received text to an existing UART (1...

I’m integrating an STM32-based board that must both read RFID tags and talk to the rest of the system over CAN. MFRC63003 is the reader. The firmware needs to: • Detect and read ISO 14443 tags, return UID and basic data blocks, and expose simple functions others can call. • Transmit and receive messages on a standard CAN 2.0 A/B bus, with configurable IDs, filters, and interrupt-driven handling. • Package each tag event into a CAN frame and, conversely, accept incoming CAN commands that trigger RFID actions or change settings. Please build this as a clean, well-documented STM32CubeIDE (or equivalent) project, using HAL or LL drivers—no blocking loops, a clear state machine, and comments that let another engineer extend it later.

...simplifies the first revision. Likewise, an onboard screen is optional; the design just needs clear expansion headers so we can snap in a small OLED or route data out over UART/SPI/I²C. The real priority is clean sensor front-ends, low-noise amplification, robust DSP/FFT routines, and smart firmware that can filter out environmental rumble while amplifying that tell-tale burst sound. If you prefer an STM32, ESP32, or another MCU/DSP, I’m flexible as long as it handles multi-channel sampling and future OTA updates. Good power management is essential because the unit may run on battery during field tests. A modular approach—separate analog front-end, MCU core, and plug-and-play sensor daughter cards—will make future temperature, pressure, or humidity add-o...

I have an STM32-based ExpressLRS build on my bench that compiles and flashes fine, yet refuses to play nicely with the controller. The stumbling block is the software side: pin maps, USART assignments, and protocol options that need to match the RF gear.

I have a very simple STM32H7 firmware that write and read to large array in RAM. I am running into what looks like memory management issues, even if I am way under the available RAM. I need someone experience with memory management on STM32 to find the issue and fix it. I expect this to be a very quick job (less than an hour) for somebody familiar, so I would need it done quickly (within 1-2 day) and at a low price (1-2 hours at your hourly rate). You don't need to own the hardware as I can test on my side. This is just the first small task on this big project, so it will lead to many more jobs if you are successful. More details are in the attached document, so please read it carefully.

...for a compact embedded IMU/GPS logger project. What I Need: Develop (and deliver) a robust, documented Python algorithm to reconstruct the trajectory or path from logged IMU data (acceleration and orientation, optionally with GPS). The emphasis is post-processing/analysis with Python. The freelancer should build and demo the workflow using a readily available, minimal embedded system (such as STM32, ESP32 or similar + IMU, with or without GPS). The hardware should be simple and reproducible, just enough to prove the workflow and verify results. If some pre-processing/filtering (e.g., bias removal, simple fusion) is best done on the embedded device, you can implement it there as well, but all position/trajectory estimation must be reproducible in Python using the raw or pre-pr...
