The development of firmware for MCU and hardware platforms requires the management of limited resources such as memory and processing power, consideration of hardware dependencies, and optimisation of performance and power consumption. This is why the optimisation of your Bill of Materials (BoM) is a vital step in ensuring the seamless operation of your device.
Â
When determining the most cost-effective MCU for your project, firmware outsourcing can often be an optimal solution. Our experts can assist you in the selection of an appropriate MCU based on your project's specifics and budget. We work closely with global chip vendors to propose several options. We will outline their pros and cons so that you can consider vital factors such as performance requirements, power consumption, available resources, and development costs.
Â
As a custom firmware development company, we update existing products with new functionality, fix bugs, and implement other required modifications. When you provide access to the existing source code, our team will analyse your current firmware and recommend the best approach to achieve your desired updates.
Â
Robust firmware security is essential, especially for devices connected to the internet or other networks. As part of our firmware engineering services, we take the following security measures:
Â
Microcontroller firmware plays a critical role in IoT devices considering that it is responsible for controlling the device's functions and communicating with other devices and systems.
IoT firmware must be designed with security in mind, as these devices can be vulnerable to attacks if not properly secured. Also, the firmware must be highly optimised for performance and power consumption, as many IoT devices are battery-powered and often operate for extended periods.
Â
Version control is a methodology that allows developers to manage changes to their codebase over time. It is crucial because it enables developers to keep track of changes and revert to previous versions if needed. It also facilitates collaboration between team members that are working on the same project.
Â
As a custom firmware development company, we carefully plan and implement over-the-air (OTA) updates. We assess them early in the device development process to ensure successful delivery, authentication, encryption, and installation on the device.
Our firmware outsourcing team also evaluates the impact of OTA updates on the device's resources, including additional memory and processing power requirements, in order to avoid performance issues.
