vocore-screen 0.1.1

Library to control the Vocore Touchscreen

Python wrapper for Vocore Screens

This repo includes some python helper scripts to easily interface with the VoCore Screen v2. Internally PyUSB is used, which in turn uses libusb.

For now this has only been tested with the 4" VoCore Screen v2 (with touch). This should also work with the 4.3" version. As the 5" version has a slightly higher resolution, this will most likely not work. Adjusting the FRAME_SIZE in image.py and the command in screen.VocoreScreen._write_start could possibly fix this.

For usage check the example.py - it should be pretty straightforward.

Working features

• Setting screen brightness
• Sending images to the screen

Getting started

Linux

• Make sure your screen in plugged in
• Make sure libusb is installed
• If you want to use the scripts as non-root, make sure to add a rule to /etc/udev/rules.d/

Windows

• Download and install the LibUSBk driver from the VoCore Homepage

Now run example.py. If everything worked, your screen should now show some test content.
