Sorry if my questions look obvious, I’m an absolute beginner (Eagle user until now).
I am trying to draw my first schematic. I have a µP, and for the moment I have implemented
only the power supply capacitors. So here is the first problem. I have added SMD capacitors.
All the same type, 0.1µ ceramic. I would expect the software to number them automatically.
C1, C2, etc… But it doesn’t. There is a C?, that’s it. The most surprosing is that if I edit
the capacitor, I can set the same reference to 2 capacitors, there is apparently no rule against it.
Is this a feature? I first thought that reference may have another meaning, but in this case,
it should not appear on the PCB, so the C? is probably the component name.
I didn’t find an explanation to this in the first 20 (or so) items of the search, whith is also
surprising. Can anybody explain me how to have an automatic numbering? Or even manual
but that forbids name reuse?
