Embedded Systems is a form of engineering that is used to integrate hardware, software, and sensors of all kinds into a single unit that can be used in all kinds of everyday machines, from cell phones to household appliances. The development of such systems requires constant proficiency and technical knowledge of the engineer that specializes in this field, called an 'Embedded Engineer'.

An Embedded Engineer is somebody who creates the firmware based on user requirements, makes sure the unit can properly and safely interact with any other device or incoming data; develops, calibrates and tests the system, and troubleshoots any problem when something goes wrong.

Here's some projects that our expert Embedded Engineer made real:

  • Developed customized control solutions for industry automation and robotics
  • Connected various sensors with different configurations and enabled communication between them
  • Preparation of vehicles for data and communications management task, such as onboard computers, devices or communication links
  • Integrate differents systems, such as GPS navigation devices or audio streaming systems in machines
  • Transfer data securely between two points, by means of communications links over wireless technologies or wired networks.

Embedded Systems technology is a complex yet powerful area for anyone trying to build something custom for their business or their personal use. A dedicated engineer can make sure that any idea a client has in mind becomes reality by providing the expertise needed. At Freelancer.com clients often hire talented embedded engineers that make all kinds of projects real. So if you have an idea that requires embedded engineering creativity, post your project today on Freelancer.com to start bringing it to life!

    I already have a working PCB built around an Xsens MTi-630 IMU and an NXP MKV56 microcontroller. What I need now is a technician who can revise the existing firmware so the remote camera head delivers rock-solid motion compensation on set. Your task is to design and embed a custom sensor-fusion routine that blends gyro, accelerometer, and magnetometer data from the MTi-630, then feed that fused orientation into the motor-control loop over CANopen. I’m aiming for a balanced mix of speed and accuracy so operators never feel lag yet still enjoy drift-free performance during long takes. You will be starting from my current codebase (MCUXpresso / NXP SDK), which already handles basic hardware abstraction and CANopen messaging. The focus is on: • Writing or adapting a quaterni...

This modification must be invisible and undetectable from the outside, meaning the device must look and behave like the original product to any observer or parking enforcement officer. Background: Standard electronic parking discs are designed to detect when a vehicle is turned off and then freeze the display at the next permissible half-hour mark.

    I need a clean, intuitive user interface built in DGUS for a 7-inch DWIN DMG touchscreen that will serve as a basic attendance system. The goal is to guide employees quickly through check-in and check-out on the display itself, with all interaction handled by touch. Here is what I expect as the final hand-over: • Complete DGUS project folder with all pages, fonts, images, and configuration files ready to flash onto the DMG series display. • Clear naming of variables, addresses, and touch regions so I can tie them to my microcontroller’s serial protocol without guesswork. I already have the hardware on my bench, so I will handle flashing and live testing; you focus on the UI logic, layout, graphics, and DGUS configuration. Simple, flat icons and legible fonts are pref...

    I have a Siemens LOGO PLC on my network that speaks Modbus-TCP and I need a clean, well-commented Python script that can both read from and write to its registers using the pyModbusTCP (or compatible) library. The goal is to end up with a small module I can drop into a larger project, so clarity and reliability matter more than flashy UI. Here’s what I expect: • A single .py file that opens the connection to the LOGO (IP, port and slave ID must be easily configurable at the top of the script). • Functions I can call for typical tasks: read_coils, read_holding_registers, write_single_coil, write_single_register (or their pyModbusTCP equivalents). • An example section (under if __name__ == "__main__": ) that demonstrates the above functions in action wi...

    I need a seasoned PCB designer located in Pakistan who can take a concept right through to production-ready files. The boards you create must interface reliably with Arduino, Raspberry Pi, and FPGA modules, so familiarity with their pinouts, signalling levels, and power budgets is essential. You’ll start by translating my functional requirements into clear schematics, then handle the full PCB layout, component selection, and DFM checks. I expect well-organised source files plus manufacturing outputs—Gerbers, drill files, pick-and-place, and an accurate BOM—with every revision traceable. If you prefer Altium, KiCad, Eagle, or OrCAD that’s fine; just let me know which environment you’ll use so I can open the files on my end. Because these boards may evolve...

    I need a miniature sine-wave transmitter board. I will supply the exact antenna footprint and the precise target frequency (it will be somewhere below 100hz, specified down to the decimal). Your task is to design a PCB smaller than 2 cm × 2 cm that generates a clean, low-distortion sine wave, feeds it to the antenna, and runs for at least one month on a single CR2032 coin cell. It has step sweep formula Long-term frequency stability, minimal harmonic content, and ultra-low power consumption are critical. Feel free to use discrete components, a low-power MCU with DAC, a numerically controlled oscillator, or any other architecture that can hit the spec while staying inside the tight footprint and power envelope. Deliverables • Complete schematic and PCB layout (KiCad, Altium...

    I need a complete mixed-signal design for an eight-channel Bluetooth communication system: four inputs for data acquisition and four outputs for actuation or stimulation. The unit must span a wide frequency range—everything from standard audio bandwidth up into the low-MHz region—while keeping each output capped at 5 V, 5 mA so it remains safe for direct human-facing applications. Because the project will handle live data, the entire chain has to support real-time streaming over Bluetooth Classic; latency has to stay low enough that an audio-rate round-trip remains perceptually seamless. Inside the enclosure, you can split the path however you wish—purely analog front ends feeding ADCs, DSP blocks, then DACs and analog output buffers—so long as the final architec...

    STM32 Sonar Protocol Firmware

    I am ready to move fast on a custom sonar project built around STM32 hardware (CubeIDE + HAL). Your task is to create production-grade firmware that: • Captures long-range sonar returns through the onboard ADC and a TUSS4470 (or comparable) front-end, with signal conditioning tuned for maximum range performance. • Streams that data in real time using a compact, binary UDP protocol—both transmit and receive paths—so it plays nicely with an existing mobile-app protocol. • Listens for run-time commands such as gain adjustments, start/stop, mode selection, and ping-rate changes, then acts on them immediately. Deliverables I need: 1. Well-documented STM32 firmware source code. 2. A clear protocol reference (frame layout, timing, byte ordering, command set). ...

    Project Description: I’m building a small ROS 2–ready mobile robot platform aimed at undergraduate and MSc robotics education. The mechanical chassis and system architecture are already defined, and I’m now looking for an experienced STM32 firmware developer to implement the motor controller firmware. This is not a vague research project — a detailed firmware specification, protocol definition, and safety model already exist. The task is to implement them cleanly and robustly. Scope of Work: You will develop firmware for an STM32-based motor controller with the following characteristics: Core functionality: - Closed-loop wheel speed control (2 motors) - Quadrature encoder input (3.3V TTL) - PWM + DIR motor driver outputs (one per motor) - Deterministic control ...
