Newbie got stuck-up on ERC

Schematic
1

Hi Mates,

I am new to KiCad and PCB designing.
I got installed the current stable version on a Win7-X64 PC and started working with a Schematic in the getting_started_in_kicad.html.
When I run the ERC check after finishing the schematic, around 6 pin not connected errors came up and I tried wiring them again etc …but not able to find the actual problem causing the error.

Please find the screenshot of the error and the ERC file.

Your schematic have folowing errors:

  1. Labels uCtoLED and INPUT nearest IC1 aren’t “connected” to any wire. The active point - a small rectangle - must lay over a wire. Just like LEDtoR or INPUTtoR.
  2. Pins in J1 connector have wrong orientation. The active points - a small circles - must be outside the symbol. You have to correct your symbol in library.

Expanding on the comment above, open circles are not-connected hints in the SCH.

eg following the open circles …

  • You have two labels, which are floating on the sheet, and have not been placed carefully enough to connect
  • The J1 wires are also not connected - as you see on IC1, a correctly placed/connected wire, then removes the open circle.

Hi Mates,

Thanks for your quick and kind support.
I have edited the component J1 and its pin orientation solved the connection issues with this particular component.
and the connection issue with uC pin 6 and R4 was the floating label, can’t we place the net labels away from the wire with a line pointing at it?

Thanks.:slight_smile:

Sure, you can do that, provided the “line pointing at it” is a Wire entity, to make a connection to the Label Point. :slight_smile:
