4. Logging setup
The VESC express has the ability to log continuously while the VESC controller is powered. This is a big
step for logging as before you could only log data from the VESC device you were connected to. Now,
the VESC-Express will be able to log every VESC device and BMS connected to CAN.
Start by installing an SD card (installation guide on page 1). The size of the SD card would depend on
your project and how long you are logging for. More CAN devices and longer logs will result in large files.
Now the card is installed, power on your VESC speed controller and connect to the VESC-Tool. If you
have connected to the VESC-Express dongle then make sure you connect to your VESC speed controller
in CAN-devices (1). Once VESC speed controller is selected click on the VESC packages tab (2).
Now click yes and you will be shown the Log User Interface. The UI is easy to use, simply check the box
of the values you wish to record, and click START. More detailed info can be found under
VESC Package > LogUI.Please note that the permanent logging upon system start, incorporating GNSS
position data will start once a sufficient number of satellites are found.
Click on LogUI (3), and information will appear on the right hand side. Please read this carefully
as it explains what the logUI does and how to use its UI. Finally, click install to write the logUI package
to your VESC speed controller. Once installed you should see a pop up like below. Click OK then power
off the VESC speed controller and power it back on.

When reconnected, and the VESC speed controller is
selected on CAN (1), you will see a pop up asking you
to loadthe logUI. If you do not see a pop then the
installation has failed, make sure the VESC speed
controller is selected on CAN and retry the
installation.
