In previous articles (HERE and HERE), we have talked about the RGB LED matrix panel as well as the RGB Matrix HAT which is the hardware interface between the LED panel and the Raspberry Pi. Today we will cover how to draw simple graphics on the LED panel.
Here the second article (first one is HERE) about how to render real time 3D stuff on a RGB LED matrix panel with a Raspberry Pi. In this article, we’ll look at the hardware interface between the Raspberry Pi and the RGB LED matrix display: the RGB Matrix HAT.
The latest GeeXLab 0.9.6.0 is available with a new support: Raspberry Pi with OpenGL desktop (OpenGL 2.1).
A new version of GeeXLab is available for all platforms: Windows (32-bit, 64-bit), Linux (64-bit), Mac OS X and Raspberry Pi (Raspbian).
Don’t know what to do with the 7-inch touchscreen display you bought for your Raspberry Pi? Transform it in a clock.
Here is a ready-to-use GeeXLab demo (OpenGL ES 2.0), that displays a clock.
The GLSL Hacker project is now officially stopped. To make a long story short, the support of Direct3D 12 as well as the upcoming support of Vulkan (when it will be available) are the main reasons that have led to a change of name.
I received last week the official touchscreen display for the Raspberry Pi. This 7-inch display has a resolution of 800×480 pixels, 140° horizontal viewing angle and supports 10-finger touch. The latest version of Raspbian integrates all necessary drivers for full functionality. Let’s test it.
