STM32 Motor Control Consulting – Remote Testing and Android Integration

This page describes one of our core services within Engineering & Firmware: STM32 motor control consulting with remote testing on your real hardware and Android-based tools for updates, telemetry and analytics.

What we do

We connect to your lab PC via secure remote access (for example VPN or TeamViewer) and work directly in STM32CubeIDE on your target hardware. We bring up and tune control loops, verify ADC and PWM synchronisation and DMA timing, and provide an Android USB application for firmware updates, bidirectional communication, user input and telemetry. Where useful, we add an ESP32 bridge for Wi-Fi or BLE access and design a clean RTOS-based architecture around it.

• Motor control firmware on STM32 with FOC and PI loops, including anti-windup and rate limiting
• Real-time integrity of ADC sampling, PWM generation, DMA transfers and interrupt timing
• Robust USB-based update and telemetry flow for field and service teams
• Android EMM app for firmware updates, parameters and data export
• Optional ESP32 bridge for wireless diagnostics, logging and OTA transport

For related services see real-time optimisation and motor drive protection and fault handling .

Typical results

• Faster bring-up and debugging on your test bench without on-site visits
• Stable control loops with verified ADC and PWM synchronisation and clean ISRs
• Reliable USB update flow and telemetry pipeline for field units and service
• Actionable analytics in the form of logs, CSV data and simple KPIs
• A clean, maintainable code base with RTOS tasks, watchdogs and CI-ready repository

Service modules

• Remote testing – secure access to your Windows lab PC and STM32 board via ST-Link; live flashing, probing and tuning in STM32CubeIDE.
• Control firmware – design and retuning of FOC and PI loops, anti-windup, rate limiting and observers for speed or torque estimation.
• Timing integrity – ADC and PWM synchronisation, DMA configuration, interrupt and latency budgeting, FPU usage and optimisation.
• Protection and fault handling – overcurrent, overvoltage, undervoltage and overtemperature logic, safe states and debounced fault handling.
• Android EMM USB app – secure firmware updates (DFU or DFUSE and CDC), command and telemetry channels, parameter UI and data export.
• ESP32 bridge (optional) – Wi-Fi or BLE diagnostics, remote logging and OTA transport for updates.
• Data-driven gain scheduling (capability) – simple data-based maps or regressors across speed, torque, bus voltage or temperature when the project requires it.
• Code quality – reviews, pull requests, documentation, unit tests and workflows in GitHub, GitLab or Azure DevOps.
• HIL and SIL support – basic test harnesses, scripts and measurement captures to stabilise regression testing.

Your deliverables

• Running firmware on your target, delivered via pull requests with documented changes and comments
• A tuning report summarising loop settings, timing, risks and recommendations
• Android USB application as APK and, if agreed, source code, including update flow and telemetry channels
• Artefacts such as logs and CSV files, example scripts, session notes and oscilloscope or logic analyser captures
• A small backlog with next steps and rough effort ranges for follow-up work

Technology stack

• IDE and tools: STM32CubeIDE and CubeMX, ST-Link, logic analyser and digital storage oscilloscope
• MCU and SDK: STM32 with HAL or LL drivers, CMSIS-DSP and Cube middleware
• RTOS: FreeRTOS or your in-house RTOS with tasks, priorities, watchdogs and health metrics
• Connectivity: USB CDC and DFU, UART, CAN; ESP32 bridge for Wi-Fi and BLE when needed
• Android (EMM): managed devices, USB host mode and secure update workflows
• Data and analytics: CSV export, basic dashboards and hooks for Grafana or cloud platforms if required

How collaboration works

• Access – we agree on VPN or TeamViewer access, configure a least-privilege account and review your lab safety checklist.
• Toolchain validation – we verify build and flash flow, measure a few critical signals and perform basic sanity checks.
• Tuning and testing – we iterate on the loops, verify timing, enable telemetry and document findings and changes.
• Delivery and review – we provide pull requests, reports and a backlog, then plan the next sprint or a structured handover.

What we need from you

• A Windows PC in your lab with STM32CubeIDE and ST-Link connected to your board
• A short README or overview of the existing hardware and firmware, including schematics or PCB PDFs and motor data
• Target use cases and acceptance criteria, for example limits for ripple, response time or thermal behaviour
• The agreed access path (VPN or TeamViewer) and your lab safety rules

Packages (examples, pricing on request)

• Remote pilot (about 1–2 weeks) – environment setup, baseline health check of ADC and PWM synchronisation, Android USB handshake and first analytics export.
• Feature sprint (about 2–4 weeks) – firmware update flow, telemetry channels, parameter UI and optional ESP32 bridge.
• Continuous support – scheduled remote sessions for maintenance, releases and ongoing optimisation.

FAQ

Can you work with our existing code base?
Yes. We work with your HAL or LL setup, your coding conventions and your CI. Changes are delivered via pull requests so your team can review them.

Do you take care of security and compliance?
We work with VPN or jump hosts, least-privilege access and logging on request. Data handling can be aligned with your internal and GDPR requirements.

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

Who owns the results?
All agreed artefacts – firmware changes, Android app source or APK and documentation – are transferred to you under the terms of our contract.
