How can work with the schematic view after prepared my test platform
I installed Fritzing and I have a mix of french and English word... I have not found how tohave all in english......
So I started to put my componment on the "Platine d'essai" (test platfrom), then I can switch to the Shematic view. I can see my componments, but all are not wired. there very tin wire.
Here is my question. I controlled 2-3 time my text platform and when I switch to the schematic view, the componment are not linked following the position of my test platfrom. If I press "Autoroute", it does not match.
After having done the platform test, should I also wired componment of the shcematic view or it would consider the test platfrom to build the schematic view....
Thank for your help
teh tin wire are call ratsnest. What is a ratsnest exactely?
Let's start with the idea of a "net". A net is a set of connectors that are electrically connected. They don't all have to be directly connected to each other. For example, if A is wired to B and B is wired to C and C is wired to D, then the "net" is A, B, C, and D, but A and D are not directly connected. In Fritzing, if A, B, C, and D are wired in breadboard view as just described, then in schematic view you will see ratsnest wires--a ratsnest wire represents some connection made in one view that has not been made in another view.
Ratsnest wires are "virtual"--they are essentially User Interface components acting as a reminder--they do not actually affect anthing directly. Furthermore, the ratsnest wires are an illustration of an unconnected net, but they do not display every possible connection in the net--just one possible way. So, based on the wiring as described above in breadboard view, in schematic view you might find ratsnest lines from A to B and A to C and A to D. And if you autoroute, you might find the routing goes from A to B, B to C, and B to D. All these different arrangements are electrically equivalent. If you switch to PCB view, you may find a different arrangement of ratsnest wires for the A B C D net.
Hope that helps,
Thank for your explicaton, but I did not undeerstand all.
What make me confusing. I make my small project in the breadboard. For exemple, I have an IC. From the pin 4, the is a resistor which then go to a femal header. Same for the pin 6, there is a resistor and another femal header.
Then if I switch to the schematic view, I should see a wire (or at least a ratsnest) from the pin 4 to the restistor, and another wire to the resistor to the header symbol. In my case, there is no wire or ratsnest to the header symbol.
Doesn't it follow the breadboard implementation?
Should I wire all componment from my schematic view?
Then later I create my PCB view, the autoroute will consider my Breadboard or my schematic view?
I thought that the schematic view will be "drawn" following the breadboard implementation.
By the way, I am still confused, because I tried to make my PCB from the PCB view. It could not complete (no worrie for that). But then I return to my breadboard view, and I saw several new ratsnests that I do not want because my breadboard componment are correctly connected...
Please save out your sketch file and email it to info .at. fritzing .dot. org. It is too difficult to to discuss this without seeing what we are talking about.
Also, what version of Fritzing are you running and on what platform?
I am sorry for my stupid question, but when you say "save you sletch file", do you mean my .fzz file?.
I running the last version of Fritinh on MacBook. I just tried to check for update and it's up to date
Yes, the fzz file.
I sent it :o)
I got the file--thanks.
I have not checked everything, but the main point is that Fritzing does not automatically wire any view. So if you make connections in breadboard view, you will only find ratsnests in the other views. You either must do all the wiring manually, or use the autorouter (or some combination of both).
It is not necessary to wire all the views--it depends on your purpose.
In terms of the ratsnest wires in breadboard view, R4 is not connected to anything in breadboard view, it is merely lying on top of the breadboard. So drawing the trace to R4 in PCB view generates a ratsnest in breadboard view. It also looks to me like R5 and R6 may never have been fully "seated" in the breadboard. You can make all the ratsnests disappear by reseating R5 and R6 in the breadboard, moving R4 onto empty breadboard holes straight above, and reseating LED1. You can tell a part is connected if all its ends are green--red means that something is not connected.
Most of the blue wires that lead into the breadboard are also unconnected at the breadboard end--notice the ends are red rather than green. Did you draw those wires or were they somehow created for you?
If you are having trouble making connections in breadboard view, try turning off "Align to Grid" under the View menu.
