Independent Dual Display Support on Firefly-RK3288 Development Board (Video)

From time to time, I’m being asked which platform can support dual independent displays, and although I noticed Mele A1000 (Allwinner A10) did support dual displays in Linux, I never really investigated how well it handles it, so I normally recommend to have a look at x86 platforms with AMD or Intel processor that specifically claim support for dual independent display. But today, I’ve noticed a developer working for T-Chip posted a nice demo on T-Firefly forums with two displays connected via HDMI and VGA. The demo shows Firefly-RK3288 development board running Android with two displays in three configurations: Display Mirroring – The same content is shown on both display. Especially useful for digital signage application, where one board can drive two displays with the same content Extended Desktop – The user interface is extended on both monitors. It’s like having a single large monitor with a 32:9 aspect ratio […]

Meet STMicro STM8S Based One Dollar Development Board

ESP8266 modules are $3 Wi-Fi boards targeting IoT applications that can be used in standalone mode, or connected to another MCU based board. But what if you don’t actually need Wi-Fi, but instead require a tiny board to control a few GPIOs? Arduino Pro mini can be used for this, but it costs about $10 on Sparkfun, and it’s certainly cheap enough for most projects. Switching to Aliexpress, you can get Arduino Pro mini clones for about $2, and a bit less in 10 pieces quantities. But you can get even cheaper and add a micro USB port with STMicro STM8S based boards that can be found for 5.5 CNY (Less than $1) on Taobao.com, or – once oversea shipping is factored in – about $1.60 to $1.70 on BuyInCoins, or Aliexpress without headers, and the version with headers sells for about $2 or more. Let’s check the board specifications: […]

$60 MarsBoard Rockchip PX2 Development Board Runs Ubuntu, Debian, openSUSE, or Android 4.4

Haoyu Electronics has made a new board similar to their MarsBoard RK3066, but instead of using a CPU module with Rockchip RK3066, they’ve used the industrial version of the chip called Rockchip PX2 dual core Cortex A9 processor. The board is also comprised of a baseboard and CPU module (CM-PX2), and based on the name of the pictures it’s using the exact same PCB: CM-RK3066 SoM, and SOM-RK3066 baseboard, but they simply replaced RK3066 by PX2, and increased the NAND flash capacity to 8GB. CM-PX2 Computer-on-Module: SoC – Rockchip PX2 dual core ARM Cortex A9 @ 1.4 GHz + Mali-400MP4 GPU System Memory – 1GB DDR3 Storage – 8 GB NAND Power Management Unit – TPS659102 Misc – TX indicator LED use for debug, Power Indicator LED 10/100M Ethernet PHY – LAN8720A Connectors – 2x 100- pin for baseboard connection, 40-pin connector (unsoldered) Dimensions – 70 x 58 mm SOM-RK3066 […]

3D Graphics Acceleration in Linux on Allwinner A80 based Cubieboard4

Allwinner A80 is a powerful octa-core processor found in development boards and TV boxes such as Cubieboard4 or Tronsmart Draco AW80. Some early Ubuntu images and instructions had already been released for A80 Optimusboard and Draco AW80, but none of these featured GPU drivers for 3D acceleration, which to be honest, has limited advantages in Linux desktop distributions since desktop environments and most apps require full OpenGL support, i.e. not only OpenGL ES, and the only ARM SoC that can provide OpenGL support without external graphics card is Nvidia Tegra K1 SoC. Having said that GPU drivers would pave the way for smooth OpenELEC / Kodi user interface support in Allwinner A80 Linux distributions. That’s only one part of the puzzle, since the GPU normally handles the user interface, while the VPU takes care of video decoding. The good news is that CubieTech release updates images for their Cubieboard4 (CC-A80) […]

WebGL Demos in Radxa Rock Pro Board Running Firefox OS 2.1

Radxa Rock Pro is a development board powered by Rockchip RK3188 quad core Cortex A9 processor, and although 2D/3D graphics acceleration via Mali-400MP4 is shown to be possible in Linux with tools like es2gears and glmark2-es2, full integration is seldom worked on, and things like WebGL may not work in web browsers. But thanks to the work of naobsd and MatchStick team, Firefox OS has been ported to this Rockchip development board, and as you’ll see in the video below, some WebGL demos work amazingly well. The hardware setup for this demo is comprised of Radxa Rock Pro development board, a 7″ LCD display with touchscreen, and some lego bricks :). WebGL demos can be found @ https://developer.mozilla.org/ja/demos/tag/tech:webgl, so you could try your own platform to see how it performs. If you own a Radxa Board Pro (or Lite), you can even build Firefox OS by yourself by following the […]
