SimpleFOCStudio by @JorgeMaker

Graphical user interface for the SimpleFOClibrary. This application allows to tune and configure any BLDC/Stepper SimpleFOClibrary controlled device, using serial port communications and the Commander interface.


  • Plug and play with the SimpleFOClibrary version 2.1+
  • Real-time tuning and configuration of the motors
  • Real-time plotting and monitoring of motor variables
  • Code generation for easier integration of the tuned parameters in your code
  • Built on PyQt5 and a standardized SimpleFOCConnector interface that can be used as a gateway form python to the SimpleFOClibrary device.


Don’t worry, SimpleFOCStudio is easy to install even if you have never used the terminal before! 😃 There are just couple of steps to take:

  1. Install Python if you don’t have it installed yet
    • We suggest to use Anaconda. Here is how to install it.
    • Once you have your Anaconda running open your terminal (on windows anaconda prompt) and run:
       conda create -n simplefoc python=3.6.0
    • Once this is done you will never have to run that command again, from now on you will just need:
       conda activate simplefoc
  2. Clone this repository or download the zip file
  3. Enter the folder containing the repository using the terminal
    • the command will be something like this:
       cd  some_path_on_disk/SimpleFOCStudio
  4. Final step of the installation is installing all the necessary libraries for the SimpleFOCStudio :
     pip install -r "requirements.txt"

Once you have done all the steps above you do not need to repeat them any more. All you need to do the next time is open your terminal in the SimpleFOCStudio directory and run the command:


Or if using Anaconda:

conda activate simplefoc

Using the SimpleFOCStudio

SimpleFOCStudio has several useful features:

  • A simple approach to tuning your motor setup
    • Form view for fast motion control PID/LPF tuning
    • TreeView for more in depth tunning and experimenting
  • Code generation for transferring the found parameters into your arduino code
  • Serial terminal integrated with various commander features

Motion control tunning windows

Once you have your application running add a device by clicking the motor button in the toolbar. You can choose either the TreeView or the FormView.

  • To connect to your device first configure the serial port by clicking on Configure button
  • Add your com port info and click OK
  • Then add the device command ID that you’ve added to the commander usually its M
    • Command M , Arduino code : command.add('M',doMotor,"my motor")
    • Command A , Arduino code : command.add('A',doMotor,"my motor")
  • Then click to the Connect button and you should be ready to go!

Code generation

SimpleFOCStudio helps you to easier transfer your carefully tuned parameters to the Arduino code. Once you are happy with the performance of your system you can automatically generate the arduino code of the parameters you have tuned. To generate the code :

  • Click on the Arudino button in the toolbar.
  • Choose which sets of parameters you wish to generate the code for and click OK
  • In the new tab you will have a code of your tuned parameters.

The generated code you can just copy/paste in your setup() function, just before calling the motor.init()

Integrated serial terminal

SimpleFOCStudio also has integrated serial terminal for easier debugging and monitoring.

Arduino code

Basically there are two things you need to do:

  1. Use the commander interface and add the motor to the commander
  2. Use the monitoring and add the motor.monitor() in the loop

Here is a mockup of the code:

#include <SimpleFOC.h>


// include commander interface
Commander command = Commander(Serial);
void doMotor(char* cmd) { command.motor(&motor, cmd); }

void setup(){
  // add the motor to the commander interface
  // The letter (here 'M') you will provide to the SimpleFOCStudio
  // tell the motor to use the monitoring
  motor.monitor_downsample = 0; // disable monitor at first - optional

void loop(){

  // real-time monitoring calls
  // real-time commander calls;
