Luca Dentella has another useful tips-and-tricks-like blog about using the Chrome browser’s functionality for interfacing with serial ports, including a pre-packaged ‘Serial Monitor’ Chrome App that is likely already compatible with your Chrome device and OS. That said, don’t expect to be using the Chrome app launcher for much longer.
I asked myself how I could create a really cross-platform interface, that is an interface that can run also on Linux and Mac. You may consider to use a programming language that has a compiler/interpreter for almost all the operating systems, like Java (a solution for the .Net Framework could be the Mono project) or Phyton. Developing a GUI with those languages however requires the use of dedicated frameworks, sometimes made by third party developers. In addition, Sun/Oracle only defined the specification of the Java’s serial communication APIs (javax.comm); you therefore need to adopt an external library (the most famous one is RxTx) that implements those APIs .
Today I’m going to describe you a way to develop cross-platform applications with the same techniques you use to develop web sites and without requiring external libraries: the Chrome Apps.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
