STM32 Jobs

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....

I need a custom ELRS (ExpressLRS) solution for drone control, utilizing an STM microcontroller instead of the original MCU. Key requirements: - Improved range - Enhanced security - Dual band - Mesh networking capabilities Ideal skills and experience: - Proficiency in STM microcontrollers, especially STM32 - Strong background in RF communication and protocols - Experience with drone control systems - Knowledge of security implementations in wireless networks - Familiarity with mesh networking technology Please provide relevant experience in your bids.

The task is to design a compact PCB that drops straight into an SCX 1/32 car so it can run on a digital track. I want the board to read the track’s reed-sensor signal, let me assign any of 20 unique car IDs in firmware, and expose a surface-mount USB-C port on the edge for easy flashing once the body shell is back on. Size must stay close to the original analogue board footprint (about 24 × 18 mm, height under 6 mm) but I can adapt mounting holes or connector positions if you have a cleaner layout idea. Power comes from the standard track pickups (nominal 14–18 V DC), so include an efficient buck or LDO to feed the microcontroller and reed circuitry. I haven’t locked the MCU yet; pick anything small, inexpensive, and easy to program—ATmega, STM32, ESP32, or s...

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 putting together a new Raspberry Pi build that will run Ubuntu rather than the standard Raspberry Pi OS. My own experience level is advanced, but I’d like another seasoned set of eyes to speed things up and help polish the system. The job focuses on: • Reviewing my current headless Ubuntu image for best-practice partitioning, bootloader tweaks, and basic hardening • Tracking down and fixing the boot-time warnings that surface in dmesg and journalctl • Suggesting and, where sensible, applying performance optimisations—overclock settings, thermal management, swap behaviour, I/O tweaks • Writing or refining a few clean Bash/Python scripts for unattended updates and off-device backups We’ll work entirely over SSH, so no hardware shipping...

I have individual, validated firmware blocks for the STM32L432KBU6 that handle an LIS3DH accelerometer (interrupt-driven), an EM4095 RFID front-end, the MCU’s internal touch-sensing controller, and a UART-based E220-400T22S LoRa module. My next step is to merge these routines into one cohesive, ultra-low-power application on our custom PCB. Power optimisation is the top priority. I want the system to remain in STOP mode most of the time, waking through the LIS3DH interrupt and periodic RTC events. When active, each peripheral must communicate reliably without compromising the sleep budget. Key points • Integrate existing C-based drivers into a single project • Configure and test the STOP-mode strategy, ensuring wake-ups from both the LIS3DH and the RTC function every t...
