Services
Engineering support across the embedded stack.
From early architecture decisions to hardware bring-up, Ferrer Engineering supports embedded product work that needs both electronics and firmware understanding.
02
Embedded Firmware
Low-level firmware in C/C++ for STM32 and embedded platforms, including peripherals, timers, communication interfaces and device logic.
03
Bring-up & Debugging
Board testing, signal validation, oscilloscope-based debugging, interface checks and firmware/hardware integration.
04
Protocol & System Integration
UART, SPI, I2C, CAN and custom protocol integration for products that need to communicate reliably with other hardware or software.
How I work
A practical workflow from idea to validated prototype.
01
Understand the system
Define requirements, constraints, interfaces and risks before starting the implementation.
02
Design the architecture
Choose the hardware and firmware structure that fits the product, not just the fastest prototype.
03
Build the electronics
Create or review schematics, PCB layout, components and manufacturing constraints.
04
Develop the firmware
Implement peripheral drivers, control logic, communication protocols and application behavior.
05
Bring up the board
Test power, clocks, signals, interfaces and firmware behavior on real hardware.
06
Validate and iterate
Fix issues, document decisions and improve the system until it behaves reliably.
Selected work
