My custom BLDC ESC is built around an STM32 MCU and should be running AM32. I compiled the code and flashed it through the boot-loader, but the board now sits completely silent—no beeps, no motor spin, no telemetry. Because the ESC is not responding, I suspect the boot-loader configuration or pin mapping is wrong, yet I’m not certain where the fault lies. I’m looking for someone who knows AM32 inside out and is comfortable debugging STM32-based ESCs. You would review the build settings, double-check the option bytes and vector table placement, make any necessary source-level tweaks, and guide me through a clean flash process. Whether that means sticking with the existing UART boot-loader or switching to an SWD/ST-Link workflow, I’m open to whatever ge...

I have an embedded project running on the STM32-P107 evaluation board and I need a seasoned engineer who can step in, understand the current state of the hardware and code, and remove every technical roadblock that appears. Tasks may range from writing new peripheral drivers and tightening real-time routines to tracking down boot or power-up anomalies and fine-tuning communication links. In short, if something on this board refuses to work exactly as intended, you will make it behave. Depth with the STM32 family, ARM Cortex-M3 cores, and hands-on familiarity with STM32CubeIDE, Keil, IAR or a comparable toolchain is essential. You should feel comfortable probing signals with an oscilloscope or logic analyser, single-stepping through register maps, and refactoring C code so th...

No companion app, driver, or registry edits—just pure hardware control. I’m happy with any microcontroller that can enumerate as a USB HID device (ATmega32u4, RP2040, STM32, etc.) as long as you supply: • A fully assembled, tested dongle ready to ship • The firmware source and brief build instructions so I can re-flash if needed • A short user sheet showing what each button press does and the range of movement speeds The end goal is a discreet, reliable gadget I can trust to keep my machine awake while passing even the kee...

I need a seasoned embedded engineer to design and implement a lean Time-Division Multiplexing protocol that funnels several high-speed ADC channels into a single, reliable UART stream. The end goal is clear: squeeze the maximum possible throughput out of the link without sacrificing data integrity. The work revolves around three core competencies—TDM protocol development, raw ADC data handling, and low-level UART communication—so fluency in each of these areas is essential. Our front-end hardware already produces digitised samples via a bespoke analog-to-digital conversion stage; your task is to move those samples efficiently over UART, interleaving them with tight framing, minimal overhead, and built-in error checking. Key deliverables • Well-documented C/C++ (or equi...

I’m building a microcontroller-based system around an stm32 and need compact, reliable embedded-C firmware that lets me read multiple sensors and move their data cleanly through standard communication channels. The core of the job is classic microcontroller programming: bring up the chip, initialise the peripherals that the sensors require (typical I²C, SPI or simple GPIO timing), perform periodic reads, apply any basic filtering the devices recommend, then expose the results over the communication protocols we agree on—UART is mandatory; CAN or USB-CDC would be a welcome extra if time allows. You will be working with the latest STM32CubeIDE tool-chain, so please be comfortable with HAL and, where efficiency demands, direct-register work. I’ll supply full pin...

I have a small STM32-based prototype that needs a tidy firmware layer to read a digital sensor running off the 3.3 V rail and perform on-board data processing. The task is focused purely on sensor data acquisition and manipulation—no motor control or external comms stacks are required beyond whatever interface the sensor ultimately uses.

I need a seasoned embedded-systems engineer to help me complete and refine firmware for an industrial solar tracking pilot we are about to install in the field. The hardware platform is an STM32-based control board that already handles basic I/O; what I need next is rock-solid actuator control logic and tight integration with the rest of the system. Key priorities • Linear-actuator position control is the single most critical feature. Accurate sun-tracking algorithms must translate to smooth, repeatable movement, end-stop detection, stall handling, and safety interlocks. • The board talks over a CAN bus to a Linux-based gateway. Your code should package position reports, health data, and fault codes into our existing CAN message set and respond to incoming commands in...

I’m putting together an STM32-based design and need clear, working guidance on driving a microSD card over SPI. My end goal is solid, repeatable read-and-write access to a FAT32 volume inside my firmware, and I’d like to lean on the FatFs library. What I need from you • A concise, well-commented C example that shows the full flow: card initialisation, mounting with FatFs, buffered reads, buffered writes and a clean unmount. • Explanations—short but precise—of the timing constraints, clocking choices and signal-integrity quirks that typically trip people up (especially when pushing speed). • Tips for handling card-to-card variations, sector alignment, power-up delays and anything else that can corrupt data if ignored. • A quick REA...

A 50 k-line codebase that Claude Opus 4.5 auto-generated now needs to compile, run and pass compliance on real hardware. It already covers most of the ANSI/VITA 46.11 specification for VPX/SOSA and MicroTCA, plus a companion host-PC provisioning tool; none of it has ever been built or executed. My goal is to take that starting point all the way to demonstrably working firmware on an STM32G0C1 MCU, delivered through STM32CubeIDE. The finished image must implement, prove and document the three key controller capabilities specified in the standard: fault tolerance and recovery, sensor monitoring and management, and in-field firmware update. I will provide the existing source tree, the compliance spreadsheet, and access to a private repo so a CI workflow can run the extensive unit and sy...
