Here's how we render a Framebuffer with #PinePhone's A64 Display Engine

https://github.com/lupyuen/pinephone-nuttx#render-colours

Let's render something more interesting on #PinePhone with #NuttX: Mandelbrot Set

https://github.com/lupyuen/pinephone-nuttx#render-mandelbrot-set

#PinePhone's Framebuffers support Animation ... Because A64 Display Engine renders Framebuffers via DMA

https://github.com/lupyuen/pinephone-nuttx#animate-madelbrot-set

Let's add a Blue Square and Green Circle as #PinePhone Framebuffers

https://github.com/lupyuen/pinephone-nuttx#render-square-overlay

Here's how we render the Blue Square and Green Circle as UI Overlays on #PinePhone's A64 Display Engine

https://github.com/lupyuen/pinephone-nuttx#render-circle-overlay

Here's how we run the p-boot Display Code on #PinePhone with Apache #NuttX RTOS

https://github.com/lupyuen/pinephone-nuttx#test-pinephone-display-engine

We captured the Display Engine Log from #PinePhone p-boot ... Super helpful for creating the Display Engine Driver for Apache #NuttX RTOS

https://github.com/lupyuen/pinephone-nuttx#display-engine-usage

#PinePhone's A64 Display Engine also supports Rotation, Write-Back and Video Scaling

Rendering graphics to #PinePhone's LCD Display with Apache #NuttX RTOS ... All shall be explained in this article

https://lupyuen.github.io/articles/de?1

#PinePhone renders graphics to the LCD Display ... By calling the A64 Display Engine and Timing Controller

https://lupyuen.github.io/articles/de?2#display-rendering-on-pinephone

#PinePhone graphics rendering gets complicated ... Because the ST7703 LCD Controller is RAM-less

https://lupyuen.github.io/articles/de?2#display-rendering-on-pinephone

#PinePhone's A64 Display Engine handles DMA, Overlay, Scaling and Blending of the Framebuffers

Rendering Colour Blocks with #PinePhone's A64 Display Engine

https://lupyuen.github.io/articles/de?4#render-colours

Let's render something infinitely fascinating with #PinePhone's A64 Display Engine: Mandelbrot Set

https://lupyuen.github.io/articles/de?5#render-mandelbrot-set

Updates to #PinePhone's Framebuffers are pushed instantly to the LCD Display ... Because the Framebuffers are connected to the A64 Display Engine over DMA

https://lupyuen.github.io/articles/de?6#animate-madelbrot-set

#PinePhone's A64 Display Engine can render Framebuffers as Overlays ... Let's render a Square Overlay

https://lupyuen.github.io/articles/de?7#render-square-overlay

#PinePhone's A64 Display Engine supports blending of 3 Framebuffers ... Let's render all 3 Framebuffers

https://lupyuen.github.io/articles/de?8#render-circle-overlay

Here's how we test #PinePhone's A64 Display Engine ... By booting Apache #NuttX RTOS on microSD

https://lupyuen.github.io/articles/de?9#test-pinephone-display-engine

"we systematically analyzed the security of
wireless communications between Smart TVs and their
Remote Controls, and based on this analysis proposed a
new attack, EVILSCREEN Attack, which exploits insecure
multi-channel remote control communication"

Let's mod #Blockly and add Custom Blocks ... For #ZigLang and #NuttX Sensors
