Hi guys, Good day! I’m asking for what language I’m gonna use for code?
If you mean Particle devices, then C and C++ are the languages you should use. You can pretty much do it in C (with the additions brought in by the Wiring framework), though most of the libraries are written in C++, so it helps to be able to at least understand C++. There is some work to bring Rust to the platform, and Zerynth has a development environment that allows you to program Particle devices in Python.
Thank you sir, God bless!
