Należy zaprogramować MCU z radiem BLE do komunikacji ze smartfonami. Firmware bez OS. Za pomocą smartfonów MCU będzie wymieniał dane z głównym serwerem. Smartfon będzie również interface użytkownika systemu. Użytkownik przy pomocy appki będzie korzystał z prostych funkcji urządzenia za pozwoleniem (czasowym bądź jednorazowym) uzyskanym z głównego serwera. Dla ułatwienia platforma hardware MCU/BLE do Waszego wyboru, to z którym macie pozytywne doświadczenia. Ograniczeniem jest energooszczędność (MCU zasilany z baterii). Doświadczenie z zabezpieczeniem przed niepowołanym dostępem oraz synchronizacja offline danych z serwerem dopełnią rozwiązanie. Wystarczy firmware dla MCU (+ appka mobilna tylko do testów/prezentacji rozwiązania). Chęć...

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’m looking for an experienced developer who can build fully emulated firmware for a DMA card. The firmware should be compatible with Windows and capable of emulating several key functionalities, including: 100% CFG The configuration space of the firmware should perfectly replicate that of a legitimate device, allowing it to be detected and recognized by the system as authentic hardware. BAR Support BAR (Base Address Register) represents the memory region inside a PCIe device. The BIOS reads this information in order to properly communicate and interact with the device. Emulation Correct BAR handling ensures that when a driver sends a request to the PCIe device’s BAR, the firmware responds with the appropriate data, effectively imitating the behav...
The original schematics and firmware sources for my existing motherboard are no longer available, yet I still need to keep the product alive and solve a series of recurring hardware failures. The immediate objective is to reverse-engineer the board in detail so I have a complete, accurate picture of how every power rail, I/O interface, and embedded controller is wired and programmed. Once that knowledge is captured, I want a refreshed design that removes today’s failure points and is ready for a short production run. Work starts with non-destructive teardown, high-resolution imaging, net tracing, and firmware dumping via JTAG/SWD or any other proven technique. From there the task moves into schematic recreation (Altium Designer or KiCad preferred), BOM generation with ...

...battery-management read-outs. All of that raw data needs to flow up to the Pi, where it is bundled, logged and pushed over a 4 G link. The Pi also runs the user interface on an onboard touchscreen. I want that interface to launch straight into a clean dashboard with drag-and-drop style widgets so I can rearrange or resize gauges, graphs and buttons while in the field. On the software side I need: • Firmware for the Arduino that publishes every sensor value plus motor state in a well-documented packet format. • A Pi-side service that subscribes to those packets, stores them, and serves them both to the local dashboard and, via 4 G, to a companion phone app. • The phone app (iOS and Android) must: – stream real-time telemetry, – o...

There is no fixed library; the user must be free to upload whichever picture they like. Threshold speed can be experimented with. Below that threshold, the LEDs can remain off or show a neutral pattern to save power. Brightness should be adjustable so the design remains visible in daylight without draining the battery too quickly. Deliverables 1. Schematic, BOM, and mechanical mounting plan that fits a 26–29″ wheel. 2. Tested firmware...

My drone refuses to finish its latest firmware update and is now stuck in an endless restart loop. I need an experienced developer who has already dealt with drone firmware quirks to track down the root cause, flash the correct binaries if necessary, and get the aircraft flying again. The work is strictly troubleshooting: no new features or redesigns—just a clean, stable fix.

...inspection system is already on the production floor, driven by C-based firmware, yet the electronics are showing their age. I need a seasoned PCB designer to breathe new life into the hardware without disturbing day-to-day operations. Your core mission is to redesign the existing boards, swap out obsolete parts, and—above all—drive down electrical noise that is creeping into both data and video paths. Why the focus on noise? It is the single biggest drag on reliability, and the current communication modules are the worst offenders. While you tackle that, you will also be refining video signal integrity, tightening power regulation, and keeping every subsystem talking happily to the next. Compatibility with the present firmware and mechanical layout is non-n...

I’m working on a project with the AVR-IoT Cellular Mini (Sequans Monarch 2 modem), where I modified the Arduino-based firmware myself to periodically transmit GPS latitude and longitude data to my backend (BE) over HTTPS. The objective is to send GPS data (latitude, longitude, and timestamp) to a REST API endpoint at a defined interval and confirm that the data is successfully received and visible on the backend. At the moment, I’m blocked by a TLS issue while attempting to configure the CA certificate for HTTPS. When I try to add the root CA certificate (ISRG Root X1 – Let’s Encrypt) to the device/modem, I get an error that says: “CA certificate input too long” Because of this issue: • The TLS handshake fails. • The HTTPS request ...
