Firmware development for equipment that can't stop

New firmware, or the firmware you already have made stable and extensible. Written by the same team that designs the hardware, so the code and the circuit agree with each other.

When companies call us

If one of these sounds familiar, this is the service to start with.

  • The equipment locks up or resetsBlocking code, missing watchdogs and poor error handling show up as random failures.
  • Every change breaks something elseThe code grew without structure and nobody wants to touch it.
  • Updates require a technician on siteWithout remote updates, every fix means travel.
  • Communication dropsWi-Fi, Bluetooth or industrial buses lose messages under real conditions.

What's included

Take all of it or only the part you need. The scope is agreed in writing before development starts.

New firmware

Architecture, drivers, control logic and communication for a new product.

Rescue and refactoring

Stabilising existing code and making it maintainable.

Communication protocols

Wi-Fi, Bluetooth, MQTT, Modbus, CAN and serial links.

Remote updates

Firmware delivered to installed units without a technician on site.

Sensors, displays and actuators

Reading, filtering and controlling the hardware around the microcontroller.

Testing

Validation on the bench and on the real equipment.

  • ESP32
  • PIC
  • MQTT
  • Modbus RTU/TCP
  • CAN
  • BLE
  • Over-the-air updates
One accountable lead
you talk to the same person from diagnosis to delivery
45+ units online
running continuously for more than six years, updated remotely
Fixed scope first

Common questions

Can you work on firmware written by another company?

Yes. We start with an analysis of the code and the hardware, then propose fixing it or rewriting the parts that can't be saved.

Can firmware be updated remotely?

Yes. We have kept a fleet of more than 45 connected units updated remotely for over six years.

How do we start?

Send a short description by email or WhatsApp. We reply within one business day, sign an NDA if needed and schedule the technical conversation.

Do you work with companies outside Brazil?

Yes. Files, code and documentation are delivered digitally, and calls are scheduled across time zones.

Tell us what the equipment needs to do

Fill in the form and it opens a WhatsApp conversation with our project manager, with your details already written. We reply within one business day and sign an NDA before the technical call if you need one.

  • We work with companies only.
  • Scope, timeline and price are agreed before development starts.
  • We don't take academic, hobby, repair or maintenance work.
  • Business hours in Brazil (UTC−3). Calls scheduled across time zones.
