Embedded Systems Engineering
Embedded systems engineering bridges custom hardware design with low-level software to create highly reliable, single-purpose computing platforms.
SOLVEO builds custom embedded software and integrates hardware components for edge processing, sensor networks, and industrial control systems, primarily focusing on ESP32 and ARM Cortex microcontrollers.
What SOLVEO provides
We don't just write software that lives in the cloud; we write code that lives on silicon. We handle the strict memory constraints, power limitations, and real-time execution requirements of embedded devices.
- Microcontroller Programming: Bare-metal C/C++ and RTOS (Real-Time Operating System) development for deterministic execution.
- Sensor & Actuator Integration: I2C, SPI, UART, and ADC/DAC interfacing for real-world data acquisition and control.
- Hardware-Software Co-design: Assisting in PCB layout and component selection to ensure software compatibility and performance.
- Edge Processing: Implementing local algorithms and logic to reduce cloud dependency and latency.
Typical Architecture (Edge Node)
A reliable embedded node requires careful scheduling and resource management. We heavily utilize FreeRTOS to segment tasks by priority.

Common Failure Points & Limitations
Embedded systems cannot easily be rebooted by a user. They must recover autonomously.
Memory Leaks: Unlike high-level web languages, C/C++ requires manual memory management. We avoid dynamic memory allocation (malloc/free) in long-running loops to prevent heap fragmentation.
Hardware Watchdogs: We implement hardware and software watchdog timers to automatically reset the system if a task hangs due to an unforeseen electrical spike or peripheral failure.
