Embedded Software & Firmware Engineering

The firmware and embedded software that makes hardware actually function. Everything else we do is this core applied to a sector.

Embedded device with HMI touchscreen and bare PCB — firmware and embedded systems by Precision Software Solutions

Firmware · Embedded Modules · Automation Software

From microcontroller to product — we own the software layer.

MCU firmware (C/C++) RTOS & bare-metal Custom embedded modules Automation & control Instrumentation
MCU Firmware — C / C++
Bare-metal · RTOS · ARM Cortex-M · ESP32 · AVR

Production-grade firmware for embedded microcontrollers — interrupt-driven architectures, peripheral drivers, bootloaders, and application logic, bare-metal or on FreeRTOS / Zephyr.

Custom Embedded Modules
Hardware + firmware · Smart devices · Full stack

Smart embedded devices and control modules built end-to-end — from hardware specification through firmware, testing, and documentation, or firmware for hardware you already have.

Automation & Control Logic
State machines · Fault handling · Fail-safe

Control software for actuators, relays, and machinery — state-machine architecture, configurable thresholds, watchdog supervision, and fail-safe fallback behavior.

Connectivity & Protocols
CAN · LIN · Modbus · OBD-II · UART · I2C · SPI

Communication stacks and protocol handlers — message encoding/decoding, gateways, and signal mapping for vehicles, vessels, buildings, and industrial equipment.

Sensors & Instrumentation
ADC · Signal conditioning · Calibration

Driver implementation and signal processing for analog and digital sensors — conditioning, calibration curves, linearization, and fault detection built into the firmware layer.

HMI & Display Firmware
TFT · OLED · LVGL · Custom UI

Embedded user-interface firmware for instrument clusters and control panels — hardware-accelerated rendering, live data, and clear indicator logic.

Engineering Evidence

From source code to validated hardware.

Real development work across embedded Linux, firmware, HMI, instrumentation, and hardware integration.
