This is mainly due to the location in which TinyCAD by default chooses to store its library files. If you follow this guide you free download a different set of libraries and install them to a different location in a directory where Users have the correct permissions. The installer is self-extracting libraries will pretty much install itself once you run it. Then all you have to do is select the installation directory - the default should be fine but read the note above if you have any Windows above XP.
The actual installation takes almost no time on my computer. Then it asks if you want tinycad run TinyCAD:. You can start to use TinyCAD with the default libraries or you can download the latest version of the libraries that I use. TinyCAD by default ships with a download old set of disorganized libraries combined with a new set of more organized libraries.
Ideally they would choose one or the other but such is life. The newer, more organized set of libraries can be downloaded by themselves from Github:. Most people rely on making their own symbols anyhow. If you click on that link downloqd will download the whole repository containing the TinyCAD libraries. This directory contains many. TCLib files. Copy all of the. TCLib files there. Now downlozd need to add all of these new libraries to TinyCAD and remove the old ones.
Start up TinyCAD and you should see a screen like this:. Select, then Removethen select, then Remove.
Do this until the whole library dialog is empty:. Drawing your own symbols is livraries necessary part of schematic capture. You should in general add all new symbols to one library - your personal library. Alternatively you can try to organize all of symbols into logical groups. This is the group for passive devices like resistors and capacitors and inductors that are not specifically through hole or surface-mount parts - just schematic symbols.
You libraties attempt an organization like that but I would recommend just using a single library for all of the parts you generate - until it becomes too large and difficult to organize. Call it whatever dowmload like and put it in the same directory as the other library files:. This will bring up a largely blank screen - your library is empty.
Right-click on the blank space and select New Symbol in the menu:. A drawing canvas will come up.
These grid settings will help ensure that the pins on the symbol you generate end up on the grid when you use them in a design. This is ljbraries very important step! Now you tknycad start drawing your part. There are three types of things you can have on the canvas when generating a part:. The most attention in this tutorial will be paid to the pins. Feel free to investigate the myriad graphical options on your own with the knowledge that the worst you can do is make the part uglier.
Cownload first place to start the datasheet. The datasheet will provide you an example symbol and the pinouts for the package you intend to use. It is very ffee to use the correct pinout! Datasheets often cover multiple packages for the same part. For example, downloaf the differences in free for the various packages of the ATMegaP:. A lot of libraries look the same! And later in the document they show several circuits which include a schematic symbol for the LM Click on the text icon on the toolbar:.
Then click the mouse somewhere in the canvas to place the text. Next we need to draw a box around the text, so click the rectangle button from the toolbar:. Using the pinout from the datasheet I added all download pins as they were shown in the datasheet. All were 30 length and Passive typed pins.
I had to increase the size of the rectangle to accommodate the text for the pin names and it ended up looking like this:. You can also add as many parameters as you like. I tend to add things like Digi-Key part number, price per unit, electrical characteristics and so forth. Two important parameters to add for some components such as capacitors and resistors are Value and Tolerance.
This is the completed dialog for the LM with me ready to Store the part in the library:. TinyCAD makes it easy to capture schematics quickly. Just download and add the costume. A blank canvas will appear where we can place all of our parts. The TO package can handle 1A of current. The actual part looks like this:. They look like this:.
