You’ll receive a fabrication-ready hardware package, well-structured firmware with compiled HEX and flashing guide, and a user-friendly desktop utility that communicates over USB, streams live sensor data, and logs to CSV. I focus on clean design, power efficiency, and dependable communication between hardware and software. Ready to start as soon as you share the sensor list and mechanical constraints

I have individual, validated firmware blocks for the STM32L432KBU6 that handle an LIS3DH accelerometer (interrupt-driven), an EM4095 RFID front-end, the MCU’s internal touch-sensing controller, and a UART-based E220-400T22S LoRa module. My next step is to merge these routines into one cohesive, ultra-low-power application on our custom PCB. Power optimisation is the top priority. I want the system to remain in STOP mode most of the time, waking through the LIS3DH interrupt and periodic RTC events. When active, each peripheral must communicate reliably without compromising the sleep budget. Key points • Integrate existing C-based drivers into a single project • Configure and test the STOP-mode strategy, ensuring wake-ups from both the LIS3DH and the RTC function ...

My security cameras stopped showing live video and recorded footage on the monitoring app. The wiring and power seem fine, so I’m convinced the problem sits on the software side—likely a mis-configuration or corrupted firmware. I need someone who can jump in quickly, diagnose the software fault, and get every camera streaming and recording again without wiping my existing footage or settings. You should be comfortable with typical NVR/DVR interfaces, remote desktop tools, and updating or rolling back firmware when necessary. Once the feeds are restored, I’d like a short explanation of what went wrong and the steps you took so I can avoid the same outage in future.

My Zephyr-based firmware for the Seeed XIAO nRF52840 is still using the factory Adafruit bootloader. I’m ready to move to MCUboot so I can sign images, enable rollback protection, and streamline DFU, but I want the application itself to remain untouched in behaviour and memory footprint. Your job is to take the existing project, strip out the Adafruit bootloader pieces, and wire in MCUboot cleanly. That means updating the board DTS overlays, partition tables, , and CMake files so the image builds and flashes through MCUboot without breaking any of the BLE functionality already in place. I’ll give you the full repo and a short read-me of the current build steps. Deliverables • Updated source tree with MCUboot integrated and all configuration changes committed &...

I have a production-ready, IGBT full-bridge welding inverter that already powers both TIG and MMA processes, yet the embedded side still needs a final expert pass before release. The control board is built around 8051 and STC MCUs running Keil C51 firmware, and every line of code directly shapes arc stability, HF start, AC balance, soft-start, and safety interlocks. The short-term goal: review, tidy, and extend the existing code so it drives the power stage flawlessly in TIG and MMA, AC and DC. That means refining PWM timing, gate-drive dead-time, current-feedback filtering, and all the little state-machine details that separate a decent welder from a great one. Core tasks and deliverables • Audit the present C51 codebase, flagging race conditions or timing pitfalls. &b...
