Eagle Hidden Pins Connectivity Problem

Community PCB Design

Hey all,

I’m new to Eagle so please excuse me. I’ve added a 74HC595 shift register to my schematic and at first, I couldn’t find the VCC and GND connections for it. Then, I used Eagle’s invoke command to get them to appear below them. But now, am in a fix, I want the shift register to be powered by +5V and not VCC because it is something like 9V and such a high voltage will fry the IC for sure.

Schematic:

I’m using a 7805A to get regulated +5V. Now, however, when I switch to the board layout, I see that the VCC of shift register is connected to the battery input which is clearly NOT what I intend. As shown:

I’m using Eagle 6. What do I do to get it to connect to +5V instead of VCC?

looking at the schematic you haven’t connected +5V to the VCC pin, it needs to connect to the end of the pin like on the other pins, not on the middle you you have

once you connect +5V to the pin it should work, VCC is just the default when you haven’t connected anything else

Further to what langwadt suggested, to make it easy to see where the connection should be, in the schematic view, in the View Layers dialog, enable the layer for pins.

Ah! Thank you very much langwadt and eejake52! :slight_smile:
