How do I compile Arduino IDE code?
Hello! So I am new to the Arduino IDE, but I still need it for a project.
So I'm trying to program code for an RS422-shield, and I have connected it to the PC through a USB. The terminal block at the RS422-shield is connected to a male Sony 9-pin connector, which I was originally supposed to connect to a female connector - USB adapter, but unfortunately I couldn't find that in any electronics store. I could only find a male connector - USB ( also, it's a RS232-connector, so perhaps that is the problem ), which is why I am using a female - female adapter ( the gray cables you can see ) to connect those two. Do not pay attention to the white cables in the background, they are not supposed to be there...
I was unable to find " RS422-shield " in the " Boards manager ", so I instead chose " Arduino UNO R4 Minima ", since that is what I envision the RS422-shield will be connected to for the end product.
However, when I try to compile ( upload ) code, I get an error message saying: " No DFU capable USB device available ", even though I have connected a USB to a RS422-shield. Do I need an actual Arduino card, or can I program with the shield alone? Or what is the issue here?
I appreciate any help as fast as possible. My project is due on Monday...
I'm sorry if I sound like a noob, because I kind of am...
