    Description: We are developing a prototype of a motor control system based on an existing PCB that uses an ATmega16 microcontroller. The current system controls the speed and torque of the main motor and the speed of a secondary motor. Inputs are presently taken from a custom-made keyboard with tactile push buttons, and motor control is achieved by pulling specific GPIO pins high or low in defined sequences. The objective of this task is to replace the physical keyboard input system with a capacitive touch LCD display, where the on-screen UI buttons will perform the same functions as the existing tactile buttons. The touchscreen interface will control motor on/off, speed, and torque, while ensuring that the existing motor control logic based on GPIO sequences remains functionally the same....

The work begins with schematic capture and component selection, moves through PCB layout, and finishes with ready-to-manufacture Gerbers, a complete BOM, and clear test guidelines. The radio link is the heart of the design, so careful RF layout, antenna matching, and regulatory-compliant power levels are essential. Bluetooth LE is my preferred protocol, though I am open to Wi-Fi or other 2.4 GHz solutions if you can demonstrate lower cost or better battery life without sacrificing performance. Please plan on: • Delivering editable design files in Altium, KiCad, or Eagle, plus PDFs for quick review • Calling out any critical components with long le...

    I need a concise Python 3 script that will run on a Raspberry Pi 5 and do the following: • Watch a single GPIO input line for the HIGH digital signal coming from my Sony camera’s built-in AI output. • As soon as that digital signal is detected, drive a separate GPIO output that energises a small 5 V solenoid for five seconds, then automatically switch it off. • Debounce or otherwise ignore any further triggers until the five-second period is complete. The camera only provides a digital signal, so no protocol parsing is required—plain HIGH/LOW logic on the GPIO pin is all I need. The trigger itself must use the Pi’s native GPIO header rather than USB or networking. I haven’t fixed the exact GPIO numbers yet; feel free to suggest sensible default...

    I’m updating the firmware for an STM32-based design and need an experienced C++ developer who is comfortable inside STM32CubeIDE. The codebase already compiles and runs on the microcontroller, but several features still require clean, well-structured implementation, performance tuning and thorough testing directly on the hardware. You’ll be working exclusively with STM32 microcontrollers; no FPGA or other targets are involved. Please be ready to pull the current CubeIDE project from my repository, build it as-is, and then extend it in C++17 (or later) while respecting the existing HAL layer and project structure. Deliverables • Updated CubeIDE project with the new or fixed functionality fully integrated • Clear build instructions and a short change log so I can ...

    The embedded system comprises 2 STM32 boards connected to their own 7 sensors, 1 motor, and 3 relays. Each is connected to a central Raspberry Pi 4 board. The RIGHT STM32 board also has a TFT ST7789 2inch display. The Raspberry Pi has its own 5-inch display (connected via HDMI) and is connected to a battery BMS via UART and controls the main ON/OFF switching of the exoskeleton system driven via a 48V 10A relay. The Raspberry Pi also controls the operation of a 5V air-pump via a relay able to deliver 1.5A. 1. Graphical user interface (GUI) developed for the STM32 to drive the ST7789 display. The detailed requirements for this GUI are presented in Figure 3. 2. GUI developed for the Raspberry Pi display. The detailed requirements for this GUI are the same as for STM32. 3. Software for...

    I’m building a brand-new tracker aimed at hunters and other outdoor enthusiasts who need to see the location of their harvested game is in real time. The core requirement is straightforward: reliable location tracking that appears instantly on a smartphone and must be as small and light as possible. The idea is that a bow hunter can easily track and find their game after a shot is taken. This would ideally be the most ethical form of locating an animal to ensure that it is not gone to waste. Here’s the functionality I have in mind: • The device gathers GPS coordinates, pushes them to the user’s phone over low-energy Bluetooth, and refreshes quickly enough to feel truly live. • When Bluetooth isn’t possible or range is lost, a secondary short-range...
