Microcontroller jobs
...software to life. On the hardware side, the priority is circuit design. I will share detailed functional blocks, power-budget targets, and regulatory constraints; you would translate these into a clean schematic that is ready for board layout (I will also welcome help on the actual PCB routing once the schematic is locked). For software, I need both the embedded code that will run on the microcontroller and the on-screen user interface logic that appears on the TV. Simplicity and reliability for elderly users are the guiding principles. You should feel comfortable choosing an appropriate MCU, writing efficient firmware in C/C++, and prototyping a straightforward, large-font on-screen menu in a framework that can later be ported to the final hardware. Please include links or br...

I’m developing a compact data-acquisition module and need a local electronics engineer in Austin who can take the mixed-signal front-end from concept to ready-to-fab documentation. The heart of the job is a clean, low-noise analog section feeding a high-resolution ADC, with the digital side handling basic buffering and a simple SPI or I²C hand-off to my existing microcontroller board. We’ll meet in person for the initial requirements review and again when hardware is on the bench so rapid tweaks are possible. I already have rough performance targets—sampling at 1Hz, 12–16-bit resolution, and a 12V single-rail supply—but I’m looking for your guidance on component selection, input protection, and clocking strategy to hit those numbers without ...

I already have raw .bin images that flash and run correctly on the Silicon Labs SI4010 RF transmitter, but I now need production-ready software that lets me interact with the chip over SPI from a host microcontroller. Here is where things stand today: • The hardware is proven, the SI4010 is wired for SPI, and I can load binaries through the existing programmer. • What is missing is the firmware layer (or host-side driver, if you prefer) that will expose reliable SPI commands so I can configure registers, inject payloads, and trigger transmissions programmatically. What I expect from you: 1. Clean, well-documented C (or C++) source that compiles in Simplicity Studio or any GCC-based toolchain compatible with the chip. 2. A concise header/API that my applicatio...
I am building an embedded feature around an MRS Electronics controller, part number 1.107.110.00, and I need clean, portable C firmware written specifically for this board. The code has to run directly on the microcontroller, so please follow embedded-system best practices: no dynamic memory, tight timing awareness, readable state machines, and clear separation between hardware-abstraction layers and application logic. I will provide the detailed register map and functional requirements after kickoff; however, expect typical tasks such as configuring peripherals, servicing interrupts, and exchanging data over the existing communication bus. Compile-time options must allow me to toggle individual features because the same image will later be scaled to multiple variants of this har...

We are developing a commercial embedded product based on an STM32U5 microcontroller running TouchGFX for the GUI and, alongside an ESP32-S2 responsible for WiFi connectivity and OTA updates. The ESP32 downloads firmware from a server and transfers it via UART to the STM32, which then performs a firmware update through a custom bootloader mechanism. Our hardware is currently in development, and we are looking for a highly experienced embedded firmware engineer who can take full technical ownership of the firmware architecture and development as a long-term partner. This is not a short-term debugging task or small assignment; we need a dedicated engineer who understands production-grade embedded systems, robust OTA implementation, bootloader design, flash partitioning, memory mana...

This board will bridge a home server's motherboard with an ESP32 microcontroller, allowing for remote power/reset control and real-time status monitoring via a web dashboard.

Boxing Speed & Reaction Time Trainer (Wokwi Project) I just built a Boxing Speed Test Simulator using Wokwi — a browser-based microcontroller simulator that lets you prototype and test circuits without physical hardware. This project is designed to give a simple reaction time training setup inspired by how boxers measure punch speed and reflexes: -> Random light cues appear on LED indicators -> You have to press the correct button as fast as you can -> Time and accuracy feedback is printed to the serial monitor Why this matters: In boxing, faster reaction time and correct hits dramatically improve performance — hitting first and accurately can change the outcome of a bout. How it works: • Four LEDs light up in a random order • The user must ...

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.

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 th...

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.

I need a compact, two-layer PCB whose sole job is to host an IR proximity sensor on one side and a WS2812-compatible LED visible on the reverse. A connector should allow these components to be connected to a separate microcontroller board. Key points to keep in mind • LED type: WS2812B but open to your suggestion • Sensor type: IR proximity sensor, e.g. VCNT2020 but open to your suggestion • Control method: the LED and sensor trace terminate on a connector so an external board can switch it. No on-board logic is required. • LED should be visible on the reverse side of the IR proximity sensor, so either should be mounted on the reverse or use a reverse-mounted LED • Board should be as small as feasible but still be easy to manufacture. If needed the desi...
