STM32 MCSDK Integration | Control Loops, PWM & ADC Sync

What we do

We integrate and harden STM32 Motor Control SDK (X-CUBE-MCSDK) projects for production hardware. From control-loop configuration to PWM/ADC synchronization, DMA paths, and sensor integration (encoder/Hall/sensorless)—we make your project deterministic, maintainable, and ready for validation.

Outcomes we target

  • Stable current & speed loops with documented margins

  • Glitch-free PWM↔ADC timing and calibrated sensing

  • Clean DMA/ISR pipelines and reliable scheduler timing

  • Portable code: CubeIDE/CubeMX projects that build reproducibly

  • Measurable performance with logs, plots, and acceptance criteria

Services

  • MCSDK Project Setup/Porting – new project creation or migration from Nucleo/EVAL to your custom board (pins, timers, ADCs, drivers).

  • Control Loop Integration – dq current and speed controllers, anti-windup, saturation handling, feed-forward and decoupling.

  • PWM & ADC Synchronization – center-aligned PWM, injected ADC sampling at current crest, dead-time compensation, SVM sector handling.

  • Sensing Chain & Calibration – shunt/Hall/LEM/DFSDM setup, offset/scale calibration, gain sanity, temperature sensors.

  • Sensor Interfaces – incremental encoder and Hall decoding; sensorless observers (SMO/MRAS/PLL) and handover logic.

  • DMA & ISR Budgeting – circular/double-buffer DMA, bounded ISRs, NVIC priority plan (with or without FreeRTOS).

  • Field-Weakening & MTPA – flux-weakening and torque optimization integrated with speed loop limits.

  • Fault Handling – overcurrent/over/undervoltage, thermal derating, kill inputs (BKIN/BRK), controlled restart.

  • Code Review & Refactor – HAL/LL hygiene, module boundaries, config headers, clear parameter sets.

  • Test Harness & Logging – scripted sweeps, telemetry hooks, plots, and regression tests.

Deliverables you receive

  • Working MCSDK Project (CubeIDE/CubeMX): .ioc + source with documented init and parameters.

  • Integration Report (PDF): diagrams, timing budget, stability margins, and test results.

  • Parameter Packs: control gains, limits, and hardware constants in headers/CSV.

  • Diagnostics & Logs: binaries/CSV, plotting notebooks (Python/MATLAB) and acceptance checklist.

  • Handover Session: 60–90 min walkthrough with your engineers.

Technical stack

  • MCUs: STM32F3/F4/F7, G4, H7, U5

  • SDK/Tools: X-CUBE-MCSDK, STM32CubeIDE, CubeMX, HAL/LL, FreeRTOS (optional)

  • Peripherals: TIM1/8 advanced timers, HRTIM (G4), ADC injected/regular, DMA, OPAMP/COMP, DFSDM

  • Motors: PMSM/IPMSM, BLDC (FOC or 6-step→FOC migration)

  • Math: CMSIS-DSP, single-precision FPU; fixed-point where timing budgets require

How an engagement works

  1. Discovery (30 min) – hardware, goals, constraints.

  2. Plan & Setup – project scaffolding/porting, pin/timer/ADC map, risk list.

  3. Integrate & Tune – control loops, PWM/ADC sync, sensors, DMA/ISR.

  4. Validate – sweeps across speed/torque/voltage/temp; pass/fail vs. KPIs.

  5. Handover – docs, code, parameter sets, and training.

What we need from you

  • Schematics/PCB, motor & inverter specs (poles, Rs, Ld/Lq if known, Ke/Kt)

  • Target PWM frequency, ADC windows, sensing topology (shunt/Hall/LEM/DFSDM)

  • Encoder/Hall details (CPR/pole pairs) or sensorless requirement

  • KPIs (e.g., overshoot ≤ 5 %, ripple ≤ X %, settling ≤ Y ms)

Packages

  • Integration Audit – code/hardware review, timing/stability plan, task list.

  • MCSDK Build-Out  – full integration on your hardware + validation report.

  • Production Readiness – robustness at corners, documentation, and team training.
    (Positioning tip: use “transparent, cost-effective pricing” or a clear price-match policy instead of “cheapest”.)

Example use cases

  • Custom board bring-up – move from Nucleo demo to your inverter with clean SVM and calibrated currents.

  • Performance lift – increase current-loop bandwidth, cut torque ripple, stabilize low-speed operation.

  • Migration – 6-step to FOC, or sensored↔sensorless with seamless handover.

  • Compliance prep – documented protection paths and test evidence for certification workflows.

FAQ

Can you integrate without FreeRTOS?
Yes—bare-metal/HAL/LL or with FreeRTOS; we size ISR and tasks to your budgets.

Do you support dual/triple shunt and DFSDM?
Absolutely—proper timing, calibration, and filtering are included.

What if MCSDK isn’t a fit?
We also deliver minimal HAL/LL projects with only the pieces you need.

Will this overwrite our code style?
No—changes are patch-based with diffs and clear rollback; we adopt your conventions.
