For the GPS receiver IPEspeed by Ipetronik, Berger Schmidt programmed the responsive web interface in HTML, CSS and JavaScript.

The GPS receiver IPEspeed has a mini web server on board and can be configured over a web interface (similar to a router). So templates for data input (formular elements and buttons) and data output (mostly listet key value pairs) as well as scripts for the data exchange between client and server were programmed.

The complete application does not need much more than 100 KB of storage, transfers data asynchronous via AJaX, adjusts to displays of mobile devices (smartphones or tablets) via Media Queries, and is downward compatible to older browser versions.
