Don't let this gap widen

Why this program matters

Without this upskilling, your team accumulates a technological gap that translates directly into productivity loss.
Organizations that don't train their talents on key topics see their competitiveness drop.
Every quarter without training is a gap widening with competitors who invest.
The cost of inaction quickly exceeds that of well-targeted training.

Learning objectives

Master GPIO, PWM, I2C and SPI control from user space on professional embedded systems.
Leverage the character GPIO interface and associated library to replace legacy file-based access.
Drive modulated outputs and read serial buses directly from user space in production.
Measure achieved latency and jitter to quantify operational limits under real conditions.
Decide when a kernel driver becomes necessary based on precision and timing constraints.
Manage access rights securely without granting full privileges to the final application.

Program

Module 1Character GPIO interface and image deployment (libgpiod, Buildroot)

Build Linux images from sources with Buildroot, deploy to target and perform updates including power-cut scenarios. Exploit the character GPIO interface via libgpiod to drive inputs and outputs with reproducible command-line operations. Practical exercises on Raspberry Pi with basic measurements and limited access rights configuration.

Module 2PWM, I2C and SPI from user space (libgpiod, spidev, i2c-tools)

Drive PWM modulated outputs and read I2C and SPI serial buses directly from user space. Use spidev and i2c-tools libraries with real sensors and actuators. Embedded target use cases with full command reproduction and verification of reproducibility after reboot.

Module 3Latency measurement and kernel driver decision (cyclictest, perf)

Precise latency and jitter measurement with tools such as cyclictest to quantify user-space limits. Analyze results to decide when a kernel driver is required. Secure rights management and real-time constraint validation exercises on physical targets with final configuration deliverables.

Our method

Training quality, guaranteed at every step

Before, during, after: we frame the brief, introduce the trainer, tailor the content and measure impact. You stay in control from kickoff to wrap-up.

Step 1

Rigorous trainer selection

Each trainer is validated on three criteria: hands-on field expertise, proven pedagogy and alignment with your industry.

Triple validation: technical, pedagogical, sectoral.
Minimum rating 4.8/5 over the last 12 sessions.

Step 2

You meet the trainer beforehand

30-minute video call between you and the selected trainer to validate the fit, adjust content and clear any final doubts.

Live briefing on goals and team context.
Veto right — we swap the trainer for free if needed.

Step 3

Content tailored to your context

No recycled slides. The syllabus is reworked from your real cases: tools, constraints, vocabulary, ongoing projects.

Hands-on cases drawn from your stack and projects.
Program co-written then validated by your team.

Step 4

Continuous quality follow-up

Live evaluations, 30/90/180-day check-ins and a consolidation plan. If the impact misses the mark, we rework it.

NPS, knowledge quizzes and skills self-assessment.
Satisfaction guarantee: fully satisfied or free rework.

A simple promise: you don't pay to discover the trainer on day one. Everything is validated upfront, by you.
