Introduction to Hilbert Curve

The Hilbert curve is a kind of curve. As long as the function is appropriately selected and a continuous parameter curve is drawn, when the parameter t takes a value between 0 and 1, the curve will traverse all the points in the unit square and obtain a space-filling curve. curve.

As you can see, the Hilbert curve is a very beautiful curve. We can use it to beautify our board and do some useful things. For example, this project ESP32 heating table uses Hilbert curve as a The wire produces a certain resistance and is used to generate heat.

Here is his resistance calculation formula, you can refer to it.

The first is how to draw the Hilbert curve,

Here I refer to the tutorial of the B station video   and use this UP code. You can check it out. Here I will put the link to the code . After entering, just click the DownloadZip button to download the code and unzip it for later use.

Then start configuring the Python environment

1. First download VScode , enter and follow the steps in the picture.
2. Download the Python interpreter, enter the Python official website , and download it according to your system version. Here I use Python 3.9.1. Note that you must check Add Python path during installation, otherwise it will be installed in vain and it will be very troublesome to configure.
3. Then we use the code file we downloaded earlier, and directly open the folder where the code file is located with vscode.
4. Press the shortcut key F1, and a search box will appear. We enter Python, find and select the interpreter, and then select the Python interpreter we just installed. If you have multiple versions, your Python versions will be listed.
5. We right-click on the file with the suffix .py and select the Run Code button to run the python file. At this time, a json file will be generated, which can be opened with Lichuang EDA.
6. 
7. These are the only three places we need to modify. You can generate the pattern you want according to your own situation.
