SEGGER Showcases & Testimonials — Real life applications of SEGGER products

Project Description: 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.

Implementation: The core of the project is built with embOS as the operating system to handle the different tasks, and emWin for the graphical user interface and user input.

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.

Project Description: 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.

Implementation: 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.

Project Description: 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.

Implementation: 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.

Project Description: The Leica Disto X3 is a distance measuring device.

Implementation: The complete graphical user interface has been implemented with emWin PRO. Multiple driver instances are used to accomplish screen rotation depending on the orientation of the Disto X3. Tactile input using positive-feel buttons is forwarded seamlessly to emWin allowing the user to control the Disto X3s menu.
