Hi! I want to ask if it’s possible to control 4 PWM pins on an ESP32-C3 mini from a Unity application over USB. For context, Unity wouldn’t talk to the pins directly — it would just open the ESP’s USB serial port and send simple text commands like “SET PIN=18 DUTY=2000\n”, and the ESP firmware would interpret those commands and update its PWM outputs. So the only thing Unity needs to do is: detect the serial port, open it, send formatted command strings, read the ESP’s “OK/ERR” responses, and keep the connection alive without blocking the main thread. Is this kind of serial-port communication reliable/possible with Unity on desktop builds, and does anyone here have experience with using System.IO.Ports or another approach for this type of hardware control?

You should probably start by making a standalone C# program that does what you want and then move it over to Unity. There shouldn't be anything in Unity that would somehow prevent that kind of thing.
It's very unlikely to find someone here who has done that very specific hardware communication thing, but if you get stuck with Unity-specific issues it's worth it to ask again because they usually can be solved with general Unity knowledge

alright, thanks!

what is your goal? there is a serial port communication asset on the asset store that creative coders regularly use for stuff

Im controlling some vibration motors with esp32
tbh i have never touched unity, but i need a simple shooting game for demonstration of my mechanical project
And I wanted to make sure it was possible in unity before i start to learn it

are you talking about
using System.IO.Ports;
