Auto tunning tab missing in pac_foc_gui

Hi there,

I’m currently working with the PAC55723EVK1 Evaluation Kit and have successfully run the FOC firmware, flashed it to the PAC device, and controlled a motor using the PAC FOC GUI in manual mode. Now, I’d like to use the auto-tune feature mentioned in the documentation. I can see the feature is present in the firmware and understand how to enable it, but the GUI doesn’t appear to have any tab or interface for auto-tuning. I’m using the latest FOC firmware version 4.5.0. Could you please help clarify this issue? Thank you!

Hello,
For the GUI auto-tuning, you will need to go to config_feautres.h in the src folder, and then uncomment the line 236: #define ENABLE_AUTOTUNE_PI. And then you can compile, flash and open the GUI. After connecting to the board by config->COM port config, you can see the auto-tuning tab.
Thanks.

Thank you for you reply.

That’s exactly what I did, but the Autotuning tab still doesn’t appear in the GUI.

Could you check the following items and tell me what you find?

  1. Open the GUI without connecting to the board. There should be the auto-tuning tab no matter the software on the board is.
  2. Erase and flash the board again. Then power off, power on. Open the GUI and connect to the board. You should see the auto-tuning tab.
    Please tell me if there is still any issue after this.
