STM32 Motor Control Consulting – Remote Testing & Android Integration

What we do

We connect to your lab PC via secure remote access (e.g., VPN or TeamViewer) and work directly in STM32CubeIDE on your real hardware. We get your control loops running, verify ADC/PWM synchronization and DMA timing, and deliver an Android USB app for firmware updates, parameterization, telemetry, and basic analytics. Where it makes sense, we add an ESP32 bridge for Wi-Fi/BLE and build a clean RTOS-based architecture around it.

  • STM32 motor-control firmware with FOC and PI controllers incl. anti-windup and slew-rate limiting

  • Real-time integrity of ADC sampling, PWM generation, DMA transfers, and interrupt timing

  • Robust USB update and telemetry path for field devices and service teams

  • Android EMM app for updates, parameters, and data export

  • Optional ESP32 bridge for wireless diagnostics, logging, and OTA updates

  • Related services: real-time optimization as well as protection functions & fault handling (separate pages)

Typical outcomes

  • Faster bring-up and debugging on your test bench without on-site visits

  • Stable control loops with verified ADC/PWM synchronization and clean ISRs

  • Reliable USB update path and telemetry pipeline for field devices and service

  • Actionable analytics in the form of logs, CSV data, and simple KPIs

  • Clean, maintainable code with RTOS tasks, watchdogs, and a CI-ready repository

Service modules

  • Remote testing — secure access to your Windows lab PC and STM32 hardware via ST-Link; live flashing, measuring, and tuning in STM32CubeIDE.

  • Control firmware — design and (re-)tuning of FOC and PI controllers, anti-windup, limiters, and observers for speed or torque.

  • Timing integrity — ADC/PWM synchronization, DMA configuration, interrupt and latency budget, FPU usage, and compiler optimization.

  • Protection & fault handling — overcurrent, overvoltage, undervoltage, overtemperature, safe states, and debounced fault management.

  • Android EMM USB app — secure firmware updates (DFU/DFUSE, CDC), command and telemetry channels, parameter UI, and data export.

  • ESP32 bridge (optional) — Wi-Fi/BLE diagnostics, remote logging, and OTA transport.

  • Data-driven gain-scheduling maps — simple maps/regressors over speed, torque, DC-link voltage, or temperature.

  • Code quality — reviews, pull requests, documentation, unit tests, and CI workflows (GitHub, GitLab, Azure DevOps).

  • HIL/SIL support — lightweight test harnesses, scripts, and measurement captures for more stable regression tests.

What you get from us (deliverables)

  • Working firmware on your target hardware, delivered as pull requests with documented changes and comments

  • A tuning report summarizing controller settings, timing status, risks, and recommendations

  • Android USB app as an APK and—if agreed—source code including update flow and telemetry channels

  • Artifacts such as logs and CSV files, example scripts, session notes, and oscilloscope/logic-analyzer screenshots

  • A small backlog list with next steps and rough effort estimates

Technology stack

  • IDE & tools: STM32CubeIDE & CubeMX, ST-Link, logic analyzer, digital oscilloscope

  • MCU & SDK: STM32 with HAL or LL drivers, CMSIS-DSP, Cube middleware

  • RTOS: FreeRTOS or a custom RTOS with tasks, priorities, watchdogs, and health monitoring

  • Connectivity: USB CDC & DFU, UART, CAN; ESP32 bridge for Wi-Fi/BLE if needed

  • Android (EMM): managed devices, USB host mode, secured update workflows

  • Data & analytics: CSV export, simple dashboards, hooks for Grafana or cloud platforms if desired

How we work together

  • Access — we agree on VPN or TeamViewer access, set up a least-privilege account, and review your lab safety rules.

  • Toolchain check — verify build and flash flow, measure a few critical signals, run basic sanity checks.

  • Tuning & tests — iteratively tune loops, verify timing, enable telemetry, document results and changes.

  • Delivery & review — deliver pull requests, reports, and backlog; plan next sprints or a structured handover.

What we need from you

  • Windows lab PC with STM32CubeIDE and ST-Link connected to your board

  • Short description of hardware and firmware (README, schematics/PCB PDFs, motor data)

  • Target applications and acceptance criteria, e.g., ripple limits, response time, or thermal behavior

  • Agreed access method (VPN or TeamViewer) and your lab safety rules

Packages (examples; pricing in your shop)

  • Remote pilot (~1–2 weeks) — set up environment, baseline health check for ADC/PWM sync, Android USB handshake, first analytics export.

  • Feature sprint (~2–4 weeks) — update flow, telemetry channels, parameter UI, optional ESP32 bridge.

  • Continuous support — recurring remote sessions for maintenance, releases, and ongoing optimization.

FAQ

Can you work with our existing codebase?
Yes. We work with your HAL or LL setup, your coding style, and your CI. Changes come as pull requests so your team can review everything.

Do you handle security & compliance?
We use VPN or jump hosts, least-privilege accounts, and logging if desired. Data handling follows your internal requirements and GDPR.

Can we keep using the STM32 Motor Control SDK (MCSDK)?
Our focus is STM32CubeIDE and RTOS-based projects, but we can integrate existing MCSDK parts where it makes sense.

Who owns the results?
All contractually agreed artifacts—firmware changes, the Android app (source/APK), and documentation—are fully yours afterwards.
