Segger taps J-link tech for headless device debug
Segger has developed a simpler way to configure a device that does not have a display based on its J-Link debugger probe technology.
The Segger emWeb tool means that connecting a device that does not have a human interface is now as easy as plugging in a USB cable. This enabled configuration via the USB port and a web browser.
The emWeb technology was launched back in 2017 for embedded web servers and has now been adapted with the technology from the J-Link probes for debugging all USB devices. This means there is no need for buttons or a display on the unit, as any PC can be used to operate the device.
One example is a printer. Instead of the usual mini touch screen, emWeb via USB enables a printer to be headless. Connecting a printer via USB allows the user to configure WiFi or IP address, paper type and print quality and status information on the PC screen. This saves the manufacturer the cost of a display, plus the design headache of where it should be placed, while also improving the user experience in the process.
Almost any IoT device with a USB port could benefit from emWeb to improve and simplify its human interface says Segger, citing headphones, speakers and solar inverters as typical headless devices.
