Motor Control 
Arduino Serial Monitor
Here I'm sending one brushless motor commands from the Arduino serial monitor. I'm using the SimpleFOC Commander interface, which is a set of commands similar to G-code.
SimpleFOC Studio
I followed the setup instructions for SimpleFOC Studio. The link to the code repo is hidden in the website title.
I got an error when trying to install the program using Anaconda.
I went to the SimpleFOC Discord server and saw that one other user had encountered this problem. I asked for help and someone recommended that I update Python to the latest version. I did that, but it didn't help. Then I went back into the terminal and looked at the command that I was using:
But I was running a more recent Python than 3.6.0! What if I don't say anything about the Python version? I tried:
and it worked!
SimpleFOC Studio is up and running!
I reported the successful command to the SimpleFOC Discord server.
In SimpleFOC Studio, I tried changing the P, I and D values in the PID controller to see the difference that it made in the motion of the motor. Then I changed the values in the Arduino code that runs on my board. The PID controller still isn't particularly well-tuned, as SimpleFOC user AdinAck noticed in my final project presentation video.
There was one glitch in the program when I first opened it; every time I gave the motor a command to move, it immediately moved back to T0. This behavior stopped when I closed the program and opened it again. I mentioned this on this SimpleFOC Community forum thread:

Here is the motor control code that runs on the SAMD21 chip and uses the SimpleFOC library. I used this code in all the other parts of the final project.
