We want to improve an existing remote update function for an IoT product. The project is based on ARM MCU. There are 2 objectives: - Using an external flash for storing and rebuilding the firmware instead of using the internal RAM - The generation of differential firmware is not currently optimized in the application project. The objective is to optimize the project's linker script to reduce the differences between firmware versions. A document explaining the project in details is attached

I need a production-ready SIAPP container that runs on the Siemens SICAM A8000 platform and acts as an MQTT client. The container must connect to a MQTT broker, read the A8000’s configured digital inputs, analog inputs and status signals, publish those values, and in the opposite direction subscribe to topics carrying status updates and control commands so the payloads can be written straight back into the matching SICAM signals. The work involves building the application on embedded Linux, packaging it as a SIAPP, and verifying it on real demo hardware. Clean logging, reconnect logic, and graceful handling of network interruptions are essential, as this will be deployed in an operational substation environment. SDK: Deliverables • Compiled SIAPP image
I’m building a low-cost, battery-powered smart cart that performs automated checkout by weighing items and identifying them with two medium-resolution (1280×720) RGB cameras. The core controller will be an ESP32, and the cart must remain within a ₹5,000–₹7,000 per-unit bill of materials. Key elements I already locked in: • ESP32 MCU • HX711 with a 0–5 kg load cell • 6-axis IMU for motion compensation • Two RGB cameras (no depth sensors) What I need from you is an end-to-end hardware design package: 1.

I need a complete RS-274X (Gerber) package for a keyboard whose primary purpose is everyday typing. The PCB should follow a conventional matrix layout, ready to drive a standard USB-based controller. Your job is to take my reference layout notes and turn them into: • A clean schematic that reflects the key matrix, MCU, and USB-C interface I’ll supply. • Layer-stacked PCB files in RS-274X format, including drill, solder-mask, silkscreen, and board outline. • The editable project file (KiCad or Altium—whichever you prefer) so future revisions are straightforward. I haven’t locked in the switch type yet, so feel free to route with clearances that would suit either mechanical hotswap sockets or a simpler through-hole footprint; your advice he...
I’m building a small sensor-interface board that lets an OV9281 1 MP grayscale camera stream 120 fps video to a host while an RP2040 microcontroller shares the same USB 2.0 link. The plan is to base the hub section on a CH334F (or any pin-compatible High-Speed USB 2.0 hub you prefer) so both the camera and the MCU appear as separate devices to the computer. What I need from you is a full KiCad project that I can send straight to fabrication: • A complete, error-free schematic showing the OV9281, RP2040, hub, power rails, clock sources and ESD/EMI protection. • A four-layer (or better) PCB layout with controlled-impedance differential pairs for D+/D-, matched trace lengths to the camera , and sensible placement for thermals. • Production files: Gerbers, d...

Setup of High-Performance GPS Tracking Backend (VPS + MQTT) Objective: Configure a VPS to act as a dedicated GPS tracking engine. It must ingest data via EMQX (MQTT), process it using Traccar (for drift filtering and mileage), and expose a secure API for the main website (hosted on ) to consume. Architecture Overview Ingestion: Trackers publish to EMQX (MQTT Broker). Middleware: A custom Bridge Script (Node.js/Python) subscribes to EMQX and forwards data to Traccar. Processing: Traccar (running "headless") handles protocol decoding, geofencing, and mileage calculation (filtering GPS drift). Storage: PostgreSQL stores the high-frequency GPS history locally on the VPS. Integration: Your Website () calls the Traccar API (via Nginx Reverse Proxy) to fetch ve...

I have a FlexRay development board built around the SPC560P50L3 MCU and I need it turned into a transparent gateway that primarily lets me monitor live communication data. The firmware must pass every FlexRay frame unchanged by default, but expose a lightweight “manipulation block” where I can intercept, log, or edit specific bytes before the frame is forwarded. Latency needs to stay as close to wire-speed as possible, so please rely on the MCU’s built-in DMA, message buffers, and dual-channel scheduler rather than heavy software copying. Gateway operation is FlexRay-only; CAN, LIN and other buses are out of scope for this iteration. I will provide the hardware, pinout reference, and any existing low-level drivers I have. Your job is to supply: • Fully c...

...control circuit for a steam-bath machine and I want it fully programmed and ready to drop into the enclosure. The heart of the job is reliable temperature management: the board must read a temperature sensor, compare it to set-points, and drive the heater and solenoid valves accordingly while keeping everything within safe limits. I’m flexible on the platform—Arduino, Raspberry Pi, PIC, or any MCU you feel best matches the load and environmental constraints—so long as replacement parts remain easy to source. If your choice supports future add-ons such as humidity or pressure sensing, all the better.
