Embedded Software Development Company

Embedded systems are evolving rapidly now. Being part of standalone systems earlier, now it extends to web, cloud, and mobile. These technologies change the way users interact with the product. With IoT extending to all industries, these systems are bringing innovation, convenience, and user experience to human life.

Time to market has been the key factor for success these days. Sunstream engineering group can set up engineering teams to deliver projects in quick turn-around, within budget. Our team of engineers is very proficient with embedded software development. We develop IoT applications and design GUI that enhances the utility of the product. 

Our services include

  • Embedded Software Development.

Embedded software has become an integral part of many devices, especially Internet of Things (IoT) devices. The embedded software development has its own subtlety and complexity which is built and integrated into any device other than the outdated computers to meet the devices requirements by controlling its limits and assigning hardware device functions. The embedded software is considered as the brain of any device and without which the device is considered as functionless equipment.

As these are the primary part of today’s IoT devices, there are quite challenges in developing the embedded software such as stability, security, and safety. Developing an embedded software for IoT devices such smart phones, smart watches, etc. without a standardized approach can make the system lose its stability by putting the user in potential risk.

Similarly, the embedded system should be developed in such a way that it is safe and does not cause any functional or critical issue in its functionality even during the varying temperatures. In the case of mobile security, the embedded software is the brain of your device and connected with your application, which makes it essential to safeguard your credentials and if not done properly, can lead to data hijacking.

  • Machine to machine communications.

Machine to Machine communications, often termed M2M/IoT is going to be the next generation of Internet revolution connecting more and more devices on Internet. M2M communications refer to automated applications which involve machines or devices communicating through a network without human intervention. Sensors and communication modules are embedded within M2M devices, enabling data to be transmitted from one device to another device through wired and wireless communications networks.

Machine To Machine Communication or M2M is a technology offered by many as part of embedded software development services by many companies where two of the same kind or separate devices information is shared automatically and streamlined. Some common examples that incorporate the M2M technology are vehicle telemetry services, smart home meters, wearable technologies, asset tracking, and supply chain management (SCM) automation. 

The primary purposes of incorporating the M2M technology in the device is to reduce the manual assistance and offer a fully automated device for the business or other purposes. The usage of M2M technology is endless across the various business sectors which includes tracking, monitoring, and estimating the time when a customer would receive the products. Not only that with the help of M2M technology one streamlines their supply chain and maintain the management equipment through their automated sensors.

  • IoT applications.

The Internet of Things (IoT) is a network of devices that allows them to communicate and exchange data with other smart devices over the Internet. The embedded sensors and software make these material things “smart.” IoT enables seamless communication between people and things by connecting everyday utilities such as home appliances, security systems, kitchen appliances, thermostats, cars, baby monitors, and more via embedded unique identifiers (UIDs). The connected devices transmit data over the internet without needing human-to-computer interaction. The IoT finds application in various private and public aspects of life like Agriculture, Consumer Applications, Healthcare, Manufacturing, Retail, Utilities/Energy, Fleet Management, Smart Cities.

  • Connectivity and protocol stack development.

The generic arrangements of protocols utilized mostly in a communications network. The protocol stack can simply be defined as an endorsed hierarchy of various layers of primary software. Initiating from the layer at the top called application layer which is the primary method of the ongoing data towards the base layer simultaneously transmitting bits. The stack dwells in every client, user as well as the server. Notably, the layered methodology lets various protocols be exchanged in and out to oblige diverse and quality different network models. It can be explained basically as a combination of protocol layers of a network that operates altogether. Not to mention that the OSI Model defining the seven layers of protocols is often referred to as a stack.

  • GUI Development.

A graphics-based operating system interface that uses icons, menus, and a mouse (to click on the icon or pull down the menus) to manage interaction with the system. A comprehensive GUI environment includes four components: a graphics library, a user interface toolkit, a user interface style guide and consistent applications. The graphics library provides a high-level graphics programming interface. The user interface toolkit, built on top of the graphics library, provides application programs with mechanisms for creating and managing the dialogue elements of the windows, icons, menus, pointers and scroll bars (WIMPS) interface. The user interface style guide specifies how applications should employ the dialogue elements to present a consistent, easy-to-use environment (i.e., “look and feel”) to the user. Application program conformance with a single user interface style is the primary determinant of ease of learning and use, and thus, of application effectiveness and user productivity.

  • Porting applications across OS (Windows, Linux, RTOS).

Embedded software often needs to be ported from one system to another. This may happen for a number of reasons among which are the need for using less expensive hardware or the need for extra resources. Application portability can be achieved through an architecture-independent software/hardware interface. This is not a straight-forward task in the realm of embedded systems,

since they often have very specific platforms like Android, Linux, WinCE, μClinux, QNX, μCOS, FreeRTOS, MQX, etc. Porting includes starting from choosing the right OS for the system hardware/application, bringing up the same in the shortest possible time, and run applications on it.

  • Driver development.

A fundamental skill that an embedded team need to master is understanding how to write drivers. Within an embedded system, there a typically two types of drivers: microcontroller peripheral drivers and external device drivers that are connected through an interface like I2C, SPI, or UART. In many cases today, microcontroller vendors provide example drivers for their chips that can be leveraged as-is or may require modifications for production. External drivers may include pseudo code, but developers are responsible for writing the driver themselves almost always.

It’s important to realize that there is more than one way to write a driver and the way that it is written can dramatically affect system performance, energy consumption and many other factors that we like to track as we develop a product. The different techniques for driver development are The Polled Driver, Interrupt Driven Drivers and DMA Driven Drivers.
