I'm using eagle for some circuit development. I had learnt the basic aspects of it, but happens i have several doubts about it:
In the symbol view of a chip, in some of them, they have the pin names available and in someothers not. When i work on my scheme
when i see the names, i can connect them by using the mouse, but when i don't see it, how can i edit the devicepackage/symbol
to see the names again?
About the autorouter.. what is the purpose of this tool? How does it help to develop boards?
Finnaly, as i'm working on a single layer, i'd like to export the pcb design into a desktop printer and then transfer it manually. I'm finding
out i was not able to define the size of my physical pcb and i'd like to print the wiring design so i can effectively transfer to the copper
and etch it by using normal ferric perchloryde, what' s the best manner of doing this?
