2. Install the drivers ​

In order to flash the firmware, you'll need some drivers, mainly the CH340 drivers, here's where to get them from:

3. Install PlatformIO IDE ​

Once Visual Studio Code is installed, open it and install PlatformIO IDE for VSCode, an extension that will allow you to connect to the tracker, build and upload the firmware.

4. Clone the firmware project ​

Make sure you close any current projects you have open or open a new window before moving forward with these steps.

1. Go to https://github.com/EyeTrackVR/OpenIris and clone the latest version from the main branch.

   1. If you do not have git installed please install it from here.

   2. Open Git Bash.

1. Change the directory to the directory that you want the firmware to be cloned. Ex: cd C:/

1. Clone the repository by entering the command: git clone https://github.com/EyeTrackVR/OpenIris.git

For more info about cloning please refer to this documentation

Do not download as a zip - please only properly clone the project, take note of the path you run the clone command in, this is where the files will be downloaded. When we open it in PlatformIO later, this path will be needed.

1. Open the firmware in VSCode by going to PlatformIO, selecting open, then navigating to OpenIris/ESP folder and opening it.
