## Interface ##

The interface with the Harp board can be done through [Bonsai](https://bonsai-rx.org/) or a dedicated GUI (Graphical User Interface).

In order to use this GUI, there are some software that needs to be installed:

1 - Install the [drivers](https://bitbucket.org/fchampalimaud/downloads/downloads/UsbDriver-2.12.26.zip).

2 - Install the [runtime](https://bitbucket.org/fchampalimaud/downloads/downloads/Runtime-1.0.zip).

3 - Reboot the computer.

4 - Install the [GUI](https://bitbucket.org/fchampalimaud/downloads/downloads/Harp%20Load%20Cells%20v1.1.0.zip).
