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software development has its own subtlety and complexity which is built and integrated into any device other than the outdated computers to meet the devices requirements by controlling its limits and assigning hardware device functions.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 (M2M) communications, frequently referred to as M2M/IoT, represent the forthcoming phase of the Internet revolution, connecting an increasing number of devices on the Internet. M2M communications entail automated applications wherein machines or devices communicate through a network without human intervention. M2M devices incorporate sensors and communication modules, allowing data transmission between devices through both wired and wireless communication 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) refers to a network of devices that facilitates communication and data exchange among smart devices through the Internet. Integrating embedded sensors and software transforms ordinary objects into "smart" entities. IoT facilitates seamless communication between individuals and objects by linking everyday items such as household appliances, security systems, kitchen devices, thermostats, automobiles, baby monitors, and more using unique identifiers (UIDs). These interconnected devices transmit data over the internet without requiring direct human-computer interaction. IoT has diverse applications in both private and public spheres, including agriculture, consumer applications, healthcare, manufacturing, retail, utilities/energy, fleet management, and the development of smart cities.

  • Connectivity and protocol stack development.

The standard configurations of protocols predominantly employed in a communication network constitute the protocol stack. The protocol stack is a sanctioned hierarchy of various layers of fundamental software. It begins with the top layer known as the application layer, serving as the primary conduit for ongoing data, while simultaneously transmitting bits down to the base layer. This stack is present in every client, user, and server. Importantly, the layered approach facilitates the interchange of various protocols to accommodate diverse network models and quality requirements. In essence, it can be described as a combination of protocol layers within a network that operate cohesively. Additionally, it's worth noting that the OSI Model, which defines the seven layers of protocols, is commonly referred to as a stack.

  • GUI Development.

A Graphical User Interface (GUI) is an operating system interface that relies on graphical elements such as icons, menus, and a mouse for user interaction with the system. GUI development is a crucial component, ensuring user-friendly interactions on embedded Linux platforms and we are pioneers in offering these services as part of our embedded Linux development services. A comprehensive GUI environment comprises four key components: a graphics library that offers a high-level graphics programming interface, a user interface toolkit that sits atop the graphics library and provides mechanisms for creating and managing dialogue elements like windows, icons, menus, pointers, and scroll bars (WIMPS), a user interface style guide dictating how applications should utilize these elements for a consistent and user-friendly "look and feel," and finally, consistent applications. The adherence of application programs to a single user interface style is crucial for ensuring ease of learning and use, directly impacting 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. Hence, porting applications across different OS environments (including Windows, Linux, and RTOS) requires expertise. Through our embedded Linux development services our engineers adapt software for diverse platforms, optimizing performance for resource-constrained environments, integrating with specific hardware configurations, and deploying software to embedded systems effectively. 
  • Driver development.

Mastering the art of writing drivers is crucial for any embedded software development services. Embedded systems generally involve two main types of drivers: Microcontroller peripheral drivers and external device drivers connected via interfaces such as I2C, SPI, or UART. Nowadays, many microcontroller vendors offer sample drivers for their chips, which can be utilized as they may need adjustments for production. External device drivers might provide pseudo code, but it's typically the developers' responsibility to write the drivers themselves. Sunstream, offers development services focusing on embedded Linux development services, as it facilitates seamless communication with microcontrollers through SPI or I2C interfaces, especially in embedded systems..

It is essential to recognize that there are various approaches to writing a driver. Hence,  choosing the right method is crucial as it can significantly impact system performance, energy usage, and other factors which need to be closely monitored during product development. The different techniques for driver development are The Polled Driver, Interrupt Driven Drivers and DMA Driven Drivers.
