OLED Display Library Setup for the Raspberry Pi featuring SSD1331

Thanks to an impressive Python library, we can connect various types of OLED displays to the Raspberry Pi such as the SSD1331 colour display. So to get this vivid, high-contrast 16-bit colour display up and running, I take a look at how to set up this library from   Luma.OLED. Additionally, I also show how to install and run the many examples available. Continue reading “OLED Display Library Setup for the Raspberry Pi featuring SSD1331”

Motor Driver for Raspberry Pi Robot using TB6612FNG

In this feature, I take another look at the TB6612FNG motor driver, but this time, with the Raspberry Pi instead of the Arduino. The H-Bridge module is the chosen robot driver for my Pi Wars entry effort. View this post for circuit examples and Python test code to get started with your own Robot Project.

Pi Camera Video Capture with OpenCV and Python Multithreading

In this article, I install the Raspberry Pi Camera which I will be using to add camera vision to a robot. Also, to maximise the performance of OpenCV and Camera, I will be using a utility to add multithreading to the Python applications. Furthermore, I include Python demo code which also supports USB webcams. Continue reading “Pi Camera Video Capture with OpenCV and Python Multithreading”

Install OpenCV onto Raspberry Pi from Shell Script

This article is a quick guide on how to install OpenCV onto the Raspberry Pi – the easy way. I will introduce a shell script that will install OpenCV and dependencies without user intervention. Furthermore, I will also introduce GNU Screen so that the OpenCV installation can be done remotely in a Virtual Terminal Session. Continue reading “Install OpenCV onto Raspberry Pi from Shell Script”
