Any Fritzing users? Can you help explain whats going on?

[Stese]

Hi all,

I've been attempting to use Fritzing to design a circuit I want to put onto a PCB in the future.

I've set up the breadboard view to replicate my real-world breadboard, and i'm happy with it.

Going into the PCB view. I've located the items roughly where I want them on the board, and have started to work on putting in the traces, whoever, i'm finding the Ratnest traces don't seem to match the breadboard at all... and I don't know why,

https://www.dropbox.com/s/u9gfn1giuy6we2e/RSTD Breakout.fzz?dl=0

is the file i've saved ,and i'm running 0.9.0 x64.

This file is showing a ratsnest line on the second MCP23017 chip between pins A1 and A2, which isn't needed. PCB does not have this connection shown at all, (but there is a ratsnest for it) Schematic view is completely empty, as i've read it can confuse matters.

I've asked the question on the Fritzing forum, but i've not had any replies yet...

Hope someone here can help,

Regards,

Steve

I have used it before and suggest you against using it Stese.
Try Eagle or ExpressPCB instead.

Also, if you have any other problem, tell me.
I could send you a layout of your ckt if you want the same.....

Hi Ketanrd01,

Thanks for the advice, I'll have a look. I'm using fritzing as it's got the breadboard view I like to work in, and also already has parts available that I need. I've found that other programs either tend not to have the parts i'm using, or make it very difficult to create new parts.

Regards,

Steve
