---+ The ESP-IDF version

The esp-idf version of hello world is almost identical to the Arduino version except the way it built.

We must first tell the idf.py that we are using an !ESP32S3 chip:

<verbatim>idf.py set-target esp32s3</verbatim>

After that we may have to clean previous builds:

<verbatim>idf.py fullclean</verbatim>

and finally we can build the hello_world program:

<verbatim>idf.py build</verbatim>

Once the program is built we can flash it and connect the serial monitor to see the results:

<verbatim>idf.py flash monitor</verbatim>

The program repeatedly runs the induction for 20 angle values between 0 and 2&Pi;. These values can easily be captured by redirecting the output to a file. I then used an editor to prepare the data to be plotted with gnuplot.

<verbatim>idf.py flash monitor | tee results.txt</verbatim>

Finally I wrote a simple Python program calculating the correct 20 sine values, which allows to compare them to the results from TinyML.
