Actually, very little of what people use is "Wiring". We provided some headers and libraries to get you some of the same experience, but there is lots, lots more going on. ( GitHub - particle-iot/device-os: Device OS (Firmware) for Particle Devices ). We didn't port the Wiring IDE. Wiring is a language, the Arduino IDE is a port of the Processing IDE. We made our Web IDE from scratch, and our downloadable IDE is running on Atom.
