Embedded Systems & Firmware

Production-minded C/C++ firmware for ESP32, STM32, Arduino-class platforms and sensor-driven electronics. This service focuses on the code running on the device — not the mobile-app UI.

WHAT YOU CAN RECEIVE

Firmware outputs ready for hardware bring-up and product testing.

Deliverables are scoped around the target board, peripherals, timing, communications and test requirements.

  • C/C++ firmware source code
  • Board support, peripheral and sensor drivers
  • ADC, PWM, timers, interrupts, DMA and low-power behavior as required
  • BLE, Wi-Fi, LoRa/LoRaWAN, CAN, UART, SPI, I²C, USB and protocol integration
  • Sensor calibration, actuator control, state machines and safety/fault logic
  • FreeRTOS tasks, queues, events and watchdog architecture where appropriate
  • Serial logging, diagnostics, test firmware and configuration support
  • Build/flashing guide, wiring/interface notes and validation evidence
CLEAR SERVICE BOUNDARY

Firmware and app development are separate — but designed to integrate cleanly.

Embedded development owns the microcontroller, drivers, device state and communication protocol. App Development owns the mobile UI/UX, Firebase/backend, user flows and phone-side BLE/Wi-Fi implementation.

CAPABILITIES

Technical depth from peripherals to wireless products.

01

MCU platforms

03

Connectivity & RTOS

BLE, Wi-Fi, LoRa/LoRaWAN, CAN, MQTT, serial buses, FreeRTOS, event handling, watchdogs and fault recovery.

04

Bring-up & debug

Peripheral validation, serial logs, test firmware, board diagnostics, power-cycle testing and structured troubleshooting.

WORKFLOW

How firmware work is approached.

  1. 01

    Map interfaces

    Define pins, peripherals, timing, protocols, data paths, power states and fault behavior.

  2. 02

    Bring up drivers

    Validate the board and each peripheral before layering on product logic and communications.

  3. 03

    Build product behavior

    Implement state machines, RTOS tasks, connectivity, storage and the agreed device protocol.

  4. 04

    Test edge cases

    Exercise disconnects, timeouts, resets, sensor faults, power cycles and recovery paths.

  5. 05

    Document & release

    Provide source, build instructions, flashing steps, interface notes and test evidence.
