protel questions friends, please come in!

And when you say the thin lines are nets, it's just telling you that the lines are connected or you have to draw them yourself. toplayer is the top layer (the line drawn is red), the bottomlayer is the bottom layer (the line drawn is blue), the top overlay is the silk screen layer (the word white is printed on the shape or something, and the display is yellow on the computer), and the keepout layer is the forbidden wiring layer (red is generally used to determine the external dimensions of the version). For single-layer and double-layer boards, these layers are more commonly used.

You don't need to put it in the project in that PCB file, you can do it) according to the upstairs expansion of hee-hee. Myself.

The thin line you are talking about is a network (net) connection, and the PCB still needs to draw the line. Toplayer is the top layer, BottomLayer is the bottom layer, Top Overlay is the silk screen layer, and the Keepout Layer is the no-wiring layer. For single-layer and double-layer boards, these layers are more commonly used.

DS18B20, a commonly used one-line temperature sensor, is easy to use and has low accuracy. The shape is similar to an ordinary transistor, and the package form is TO-92, you can directly use the triode TO-92 package in Protel, pay attention to the pin order.

I don't know how you ds18b20 do, do gadgets, make a liquid crystal perpetual calendar and temperature, of course, use ds18b20 to measure temperature, and then use infrared remote control to adjust the time, this is an idea you can do it, I just learned the microcontroller that will make this thing, hehe, you can communicate when you have time...

Who doesn't want your score, since you think it's a waste, I guess no one dares to ask you anymore! Ha ha.

What is earthworm-shaped, is it an arc-shaped line? If so, press shift+space to select the one you want.

It's best to have ** attached, so that people can see it at a glance, and it will be better to help you analyze the problem.

Why don't you refresh it.

You look at your cabling rules set.

I don't know what the situation is, but I'll guess if it's arc-like or not. If it's an arc, you must have pressed the shift+spacebar, and when you press this key to trace the line, it's a curved arc.

I used an example of a diagram to demonstrate it to you, you can take a look at my legend, I hope it will help you.

You can use the netlist comparison to generate the schematic and the PCB netlist, and then select the comparison netlist to see if there are any errors.

The shortcut e s p then click on the line you need to check, and all the originals on this line will change color, and just compare them with the schematic one by one. After the check is complete, X A cancels.

If you have the patience, draw your own or go online to find someone else's library.

Or simply put a 5-pin single-row head5. In the future, when soldering components, just pay attention to the common end and don't make a mistake.

This kind of thing with only a few legs, you can draw it yourself, and you don't need to have a ready-made component library for everything.

What can be done in two minutes, you can completely wrap it yourself!

It is said that it is said that Ha!

It is said that it is caused by Protel's poor support for new multi-core computers, and I often encounter it, very headaches, most people on the Internet say to change DXP, but new things are always not used to it!

Sometimes I have to delete the library in the PCB file, but I can't get in, so I usually close the protel and modify the name of the library file, and then reopen it and delete it again!

Sometimes click on the right keyboard, set the program compatibility mode, compatible with the previous 2000, XP, 98 OK, you have to do it again.

Sometimes it seems like you have to play both at the same time.

Sometimes neither approach works.
