# Troubleshooting Feelix

{% hint style="danger" %}
The Feelix Mini-Driver board needs to be connected to the external power supply to work properly. The USB port can only be used to download/upload the Arduino code. The motor can **NOT** be powered through the USB port. *Hardware damage may occur.*
{% endhint %}

## General

#### Motor is not behaving as expected

* [ ] Check if the power supply is connected.
* [ ] The motor draws more current than the external power supply can provide.
* [ ] The motor temperature is **very hot**. Wrong settings could be applied to cause this. **Let the motor cool down** before continuing.
* [ ] Make sure the Feelix Mini-Driver is running the [latest code](https://docs.feelix.xyz/downloads/c-library#arduino-library-feelix-design-tool): If you are using your own code, please revert to the stock version to verify whether it is still functioning correctly.

#### **Code is not compiling**

* [ ] Check if [**all dependencies**](https://docs.feelix.xyz/uploading-files/simplefoc) are installed
* [ ] Check if you have selected the correct board in the Arduino IDE. *Feelix Mini-Driver uses the STM32F401RE*.

#### Feelix Mini-Driver is not recognized

* [ ] Check if your computer recognizes the microcontroller when its connected via USB. In windows this can be verified by the "Device Manager." 
* [ ] Make sure the port is not in use by another program (e.g. Serial monitor of the Arduino IDE).
* [ ] Try the **RESET** button.
* [ ] Check if **STM32CubeProgrammer** is still able to detect the device in **BOOT mode**.
* [ ] It is recommended to use the cable provided.
* [ ] Test it on a different USB port or computer if possible. 

## Feelix - Haptic Design Tool

#### The Feelix Mini-Driver does not connect with the Feelix Haptic Design Tool

* [ ] Make sure the device is in **RUN mode**. The pink colored LED in the Feelix logo should blink periodically
* [ ] Try to restart Feelix in case the microcontroller is recognized by the computer but not by Feelix. Otherwise follow the steps at "Feelix Mini-Driver is not recognized". 

#### Motor is not behaving as expected

* [ ] Try to [recalibrate ](https://docs.feelix.xyz/uploading-files/broken-reference)the motor
* [ ] Make sure the right number of pole-pairs are specified ([see hardware settings](https://docs.feelix.xyz/uploading-files/broken-reference))\
  If not, recalibrate the motor.

#### Motor cursor does not move

* [ ] Check if the magnetic encoder is still working:\
  Upload example code from the [FeelixEffect library](https://docs.feelix.xyz/downloads/c-library#arduino-library-for-exported-feelix-effects) to read the encoder value \
  \&#xNAN;*Arduino IDE > examples > Feelix MiniDriver Effects > test > sensor.*
* [ ] If the sensor value is not read, the issue is probably caused by a broken sensor.

#### Feelix is not loading properly

* [ ] ***Issue occured after update?*** Go to 'help' > 'development tools'.
* [ ] Search for 'application' in the development tools.
* [ ] Clear all data.
* [ ] Restart Feelix.

#### If nothing is working..

* [ ] Delete the Feelix Mini-Driver from microcontroller settings window.
* [ ] Restart Feelix Host software.
* [ ] Reconnect to Feelix Mini-Driver.
