SEGGER offers a complete portfolio for the developer of firmware for embedded systems. Below are examples where multiple components have been used to demonstrate different use cases.
SEGGER Showcase projects
SEGGER Weather Station
The SEGGER Weather Station demonstrates how to create an IoT Node to communicate with an IoT Cloud Service.
Secured communication via MQTT
Secured communication via HTTPS
Device configuration and provisioning
Creating and parsing JSON data
The IoT Temperature Node registers with the service and publishes its sensor data. The data is analyzed in the cloud and made available on a website: http://weather.segger.com
The Remote Display showcase project demonstrates how an embedded system can be used as a remote display to another embedded system, separating the display unit from the control unit.
IP based communication via USB
User interface and game controller
The project connects both units with a USB cable that actually serves as an IP connection in order to establish a Virtual Network Computing (VNC) connection. The second USB-Host port on the emPower-USB-Host board is used to connect the game controller.
To connect the two systems, the project uses emNet with emUSB-Host and emUSB-Device using IP over USB. The user interface data is exchanged by using emWin VNC Server and a version of emVNC Client that runs on a microcontroller based system.
Using the application
The emPower-USB-Host and the STM32F746G discovery board are connected via USB (CN12 USB High Speed for the discovery board). Then both boards are powered. To establish the VNC connection a button appears close to the top right corner of the display. By touching the button, the two boards establish the IP connection.
Pressing button "A" on the game controller starts the game. To evade the asteroids, the game pad on the controller is used.
This application uses emBASIC, our feature-rich BASIC interpreter designed for embedded systems. This project is available on target hardware as well as the Windows simulation. It uses various SEGGER embedded software products such as embOS, emFile, emWin, emUSB and emNet, making it easy to create powerful applications using the components.
This application can be used to learn the computer programming language BASIC, to easily "play" with SEGGER software, but also to create usable applications on real hardware without much effort. Created programs can be stored in the cloud or on the device. Generated programs can be executed stand-alone, by simply powering up the board.
The core of the software is emBASIC, SEGGER's implementation of the BASIC programming language for embedded systems. It can seamlessly interface to a lot of SEGGER software libraries, making access to the internet, cloud storage, USB Keyboards and easier.
In this application, emBASIC uses SEGGER's embedded software as key components. embOS provides the capability to run multiple tasks, servicing networking tasks and USB devices. emNet provides Internet and LAN connectivity. The IoT Toolkit, with emSSL, provides communication to Dropbox where programs can be stored securely. emUSB-Host provides access to flash storage devices for portable storage. emFile provides the file system framework for USB flash drives, on-board NAND devices, and removable SD cards. emWin provides the graphic capabilities of emBASIC and also enables it to display a console on an LCD. And built into emBASIC is the ability to shrink and expand data using emCompress.
Using the application
Two builds of the application are available, one for target hardware and one in the simulation. Both builds use the same source code of application and software libraries and behave in an identical way. BASIC programs written in the simulation can be executed in the same way on the target hardware. The simulator is a great way to write simple yet powerful applications in BASIC and is a great way to make first steps into the exciting world of programming.
Some sample BASIC programs such Conway's game of life are also available for download.
In a special version (available upon request), the command line interpreter can be controlled via network and secure shell using emSSH.
Flasher Portable Plus
Flasher Portable Plus is a SEGGER product showcasing an end product intended for service technicians and application engineers. Engineers can easily select an image stored on this Flasher and start programming with just a couple of button presses.
Flasher Portable Plus has been developed by SEGGER engineering using Embedded Studio and J-Link and J-Trace probes during development. The core of the software is created by using SEGGER RTOS and software products. embOS provides the capability to run multiple tasks, programming tasks and USB communication tasks. emFile provides the file system framework to store the firmware images in the memory of Flasher Portable Plus. This can either be done by using the J-Flash software or by using the MSD mode of the Flasher. The user interface has been created using emWin.
"Using SEGGER's products has been a great move for our firmware. SEGGER’s product reliability and support have substantially facilitated our firmware development."
Jason Schlessmann, adidas Wearable Sports Electronics, U.S.A.
"I am actively using the J-Link Debugger (Ozone) on several PCs and targets and I am very impressed with the functionality of this version. I am also using the SEGGER Real-Time-Terminal on my Cortex-M0 target (which does not support SWO), directly in J-Link Debugger and it works great as well."
Volkmar Schwert, Miele & Cie. KG
"I have worked using emWin for a week now and I am excited how fast and how well the library works and how easy it is to integrate. Fantastic."
Original: "Ich arbeite sei einer Woche mit emWin und ich bin begeistert wie schnell und gut die Library funktioniert und auch zum Anbinden ist. Echt super."
Thomas Karer, ARRI Cine & Video Geräte, Austria
"Since I started the ARM based project about 3 years ago, I have used your embOS, emFile, and your J-link emulator. They all work great. I am especially happy about the performance of the embOS. My application is a multitasking application including the audio, and real-time video capturing, Flashing writing, and at the same time sending the video to the remote site through a RF radio interface. Without your embOS, I can hardly imagine how I could do all these tasks."
Jimmy Wang, Working for a southern California based company, USA
"We bought a couple of Flasher-ARM devices. We could immediately use them for stand-alone programming of new boards. Flawless software, flawless hardware, a really beautiful product. Thanks for making this available."
Marcus Simons, YiG Engineering, The Netherlands
"I am using emWin for a week now and I am thrilled. This is a very good software package! Thanks to the good documentation and the many examples it is easy to get started. I think we made a very good choice."
Original: "Ich arbeite seit letzter Woche mit emWIN und bin total begeistert. Ein sehr gutes Softwarepaket ! Man kann sich Dank der guten Doku und den vielen Beispielen schnell einarbeiten. Ich glaube wir haben hier eine gute Wahl getroffen."
Dipl.-Ing.(FH) Martin Zeh, software developer, Erhardt + Leimer GmbH, Germany
"I would like to say HUGE THANKS for the incredible work and decision you have made with the Segger Embedded Studio. We have been using this tool a lot recently altogether with Nordic nRF52 (integrated on u-blox NINA-B1). We absolutely love this tool - it gives us great flexibility (simple project management via XML files), stability and speed. We have been using the IDE seamlessly across all OS platforms without a hassle. I can't see myself going back. Thank you."
Pavel Hübner, Co-Founder of HARDWARIO, Czech Republic
"I can vouch for 'It simply works!' I won't do any embedded stuff without at least a J-Link."
Gawie de Vos, Sulani, South Africa
"SEGGER embOS is implemented on each and every electronics control system in the Forze III hydrogen racing kart. During testing and racing, sensordata is vital to gain knowledge about the karts performance. Using emFile, we were able to log all of our sensor data on an SD card. For the live feed to the pit, we needed a telemetrics system. Using emNet made it possible to develop such a system on short notice, while guaranteeing reliability."
Koen Lubbers, Greenchoice Forze, The Netherlands
