DataTables erver-side processing (5,000,000 rows)

DataTables’ server-side processing mode is a feature that naturally fits with Scroller. Server-side processing can be used to show large data sets, with the server being used to do the data processing, and Scroller optimising the display of the data in a scrolling viewport.

When using server-side processing, Scroller will wait a small amount of time to allow the scrolling to finish before requesting more data from the server (200mS by default). This prevents you from DoSing your own server!

This example shows Scroller using server-side processing mode and 5 million rows. Important This particular example uses ajax as a function to fake the data to show Scroller’s ability to show large data sets. It does not have a real database behind it! You would normally not use ajax as a function to generate data, but rather as a url for where to fetch the real data!

In this example we also enable the scroller.loadingIndicator option of Scroller to show the end user what is happening when they scroll passed the currently loaded data.

Frequently Asked Questions
Here are some of the most frequently asked questions regarding the PINE64. If you don’t see your question here, please visit Pine64 forum, http://forum.pine64.org, for more info. Thank You!

What is Single Board Computer?
A single-board computer (SBC) is a complete computer built on a single circuit board with microprocessor(s), memory, input/output (I/O) and other features required for a functional computer. SBC were made as demonstration or development systems, for educational systems, or for use as embedded computer controllers. Many types of home computer and portable computer integrated all their functions onto a single printed circuit board.

What is Pine A64?
The Pine A64 is an index card sized 64-bit single board computer. It can perform like your desktop or portable PC with browsing the Internet, playing games, watching video, and execute programs like spreadsheets and word-processing. The Pine A64 board can also play ultra high definition 4Kx2K video.

Why 64-bit processors really matters?
The ARM 64-bit processor significantly increases performance over its 32-bit counterpart. Besides the performance increase, the 64-bit processor is more power efficient and consumes less energy.

How powerful is Pine A64 CPU processors?
The Pine A64 CPU is quad-core ARM A-53 64-bit processor and runs at 1.2GHz. The CPU’s MIPS benchmarks around 11,040 which makes it capabilities roughly equivalent to the Sony PS3’s level of performance or a netbook running AMD E-240 CPU at 1.5GHz.

How powerful is Pine A64 GPU processors?
The Pine A64 GPU is dual-core MALI-400 MP2 and runs at 500MHz, capable of 1.1 Gpixel/s throughput. Graphics capabilities are slightly higher than the original Xbox’s level of performance. The GPU provides OpenGL ES 2.0, hardware-accelerated OpenVG, 4Kx2Kp30 H.265 decode, and 1080p60 H.264 high-profile encode and decode.

Does Pine A64 board need a heatsink?
The SoC chip used in the Pine A64 is the same SoC design that is used in a tablet. Heatsink requirement will directly influenced by each application and case design.

What type of hardware interfaces that Pine A64 have?
Depending on the model, all the Pine A64 has 46 dedicated GPIO pins, three UART, two i2c bus, two SPI bus, i2s audio, SPDIF out, IR receiver, Speaker out, 3v3, 5v, and ground. In the “PLUS” model, there are additional three ports: CSI-Camera, Touch Control, and DSI-LCD Panel.

Can I add additional system memory?
No.

What is Pine A64 operating temperature?
The Pine A64 operating temperature qualified range from -20°C to 70°C.

What is the difference between “BASIC” and “PLUS” model?
Two models are available: Pine A64 “BASIC” and the Pine A64+ “PLUS.” The “BASIC” model is the low-cost variant of the Pine A64 board. It has 512MB system RAM and 10/100 Mbps Ethernet port. The Pine A64+ “PLUS” model has 1GB system RAM, Gigabit Ethernet port, camera port, LCD panel display port, and touch control port. For Android users, we strongly recommend the Pine A64+ “PLUS” model due to the larger system memory size and for a better user experience.

Can I connect a keyboard and mouse to the Pine A64 and act as a computer?
Yes, most existing USB keyboard and mouse can work with the Pine A64 board.

What are the Pine A64 dimensions? What about the weight?
The Pine A64 board measures 127mm x 79mm x 21mm (or roughly 5.00″ x 3.11″ x 0.83″) at 46 grams.

Which SoC are used in the Pine A64 boards?
Both BASIC and PLUS model uses the Allwinner A64 SoC. The SoC contains a quad-core ARM Cortex A53 64-bit CPU with floating point, running at 1.2Ghz, and a dual-core MALI-400 MP2 GPU running at 500MHz. The GPU has a high performance 3D core accessed using the supplied OpenGL ES2.0 and OpenVG libraries.

Why use the Allwinner A64 SoC?
Cost, performance and reliability.

How does the Pine A64 boot?
With the microSD card inserted in the card slot, all files necessary for booting should be installed in a microSD card with FAT32 partition.

What operating systems do the Pine A64 board support?
Android Lollipop 5.1 or Ubuntu with Kernel 3.10 are available for you. Both comes with 64-bit version. For Android users, we recommend using Pine A64+ “PLUS” boards which has a larger system memory. In addition, we also work with openHAB (http://www.openhab.org) for IoT (Internet of Things) application. The OS is stored on the microSD card; it is a straightforward process to replace the root partition on the microSD card with another ARM Linux.

Will the Pine A64 run Microsoft Windows or Windows RT OS?
No but we are working on it. Check back here frequently for updates.

Which Linux runs on the Pine A64 board?
Ubuntu and Debian runs on the Pine A64 board.

Can the Pine A64 run Android?
Yes, Android Lollipop 5.1 64-bit OS runs natively in Pine A64 board. We strongly advise you run Android on Pine A64+ “PLUS” model due to the larger system memory size for a better user experience.

What is the power requirement?
The board is powered by +5v microUSB port. Exactly how much power is required, in terms of current. (mA), is depending on what you hook up to the board. An official 2.0A (2000mA) power supply is available at the Pine64 store with ample power to run the board for most applications.

What is size of the microSD card I need?
For Linux OS, the minimum microSD size can be as low as 4GB. For Android OS, we recommend no less than 8GB. Besides OS space requirement, please also calculate the free space you need to install additional packages or make programs/data of your own.

What capacity of the microSD card can the Pine A64 support?
The Pine A64 board supports SD, SDHC, and SDXC format microSD card – this means the largest capacity is 256GB. Please note that if a microSD card is formatted as an FAT32 file format, the maximum capacity is 32GB.

How about support for other storage devices?
You can also attach a USB stick or USB hard drive to provide extra storage.

What happens when the Pine A64 board brick?
Just simply restore the Pine A64 board by re-flashing the microSD card.

Does the Pine A64 support networking?
The “BASIC” model has built in 10/100Mbps wired Ethernet and “PLUS” model has built in Gigabit wired Ethernet. There is a Wi-Fi and Bluetooth native expansion port on both models.

Is there wireless expansion for Wi-Fi and Bluetooth?
Yes, the Pine A64 has the reserved expansion port for Wi-Fi and Bluetooth. The various Wi-Fi and Bluetooth daughter boards are available at Pine64 store (https://shop.pine64.org).

Is sounds supported through HDMI?
Yes.

Is sounds supported through SPDIF?
Yes it is through the output port located at the “euler“ bus connector.

Is there a mic port on the Pine A64?
