Connecting Zoolark to a Computer

Zoolark is capable to communicate to a computer which allows waveform to be displayed on a larger screen and have data exported. If you need to update firmware, please read next section.

To download the software Zookee first and follow the procedures. You can also check out this video for better demonstration.

  1. Download the software Zookee from our Github repository, click the link below

  1. Unzip the folder, then click the “Zookee” file located in the folder. This is an executable file.

  1. The interface of Zookee is introduced in the following picture.

  1. Connect Zoolark to your computer’s USB port and turn on the device. Click Refresh icon to get the port and then Link the device. Click Run to display the data onto your computer screen.

  1. Once connection has established, the software will display Zoolark’s waveform. You can open the cursor function for more detailed measurement. The Export icon allows data to be exported in .csv format.

Instructions for Firmware Updates

Firmware is a piece of machine code to be flashed into the hardware and enables certain functionalities of the device.

The initial firmware was released on July 2021 during the Kickstarter product launch. This firmware did not support computer communication. All firmware version released after Oct 31, 2022 improved screen refresh rate and have supported computer communication.
