Visualized Device Tree Configuration Issue

[HHJ]

When we were configuring SDA in the visualized device tree, we forgot which button for SDA we should click (as shown in the red box in my picture). Now all the buttons for SDA are off, and the drop-down box for SDA can't assign other pins either. How should we solve this problem? Does the official provide any tutorials on operating the visualized device tree?

Hi,

The SDA is greyed out probably because maybe that pin is being used elsewhere. 

You could take a look at the following documentation for a detailed understanding:
