Drawing Charts in Android with AChartEngine Library

AChartEngine is a charting library for Android applications that currently supports the following chart types: line chart area chart scatter chart time chart bar chart pie chart bubble chart doughnut chart range (high-low) bar chart dial chart / gauge combined (any combination of line, cubic line, scatter, bar, range bar, bubble) chart cubic line chart They announced that new chart types would be added in future release (Current version is 0.7.0). You can follow the updates for the library on Google Code or Facebook at http://www.facebook.com/achartengine. You can download the aChartEngine library on Google Code. You can also download some demo code such as TemperatureChart.java which display the following chart with just 100 lines of code including comments. Here’s the code (TemperatureChart.java) to display the Chart above:

Meet the Wifi SD Card: Toshiba FlashAir

Toshiba is currently showcasing the Toshiba AirFlash – a new Wifi-Enabled SDHC card – at IFA 2011 in Berlin (2-7 September 2011) The card features an embedded wireless LAN chip that allows it to both transmit and receive files wirelessly. The FlashAir is reportedly the world’s first SDHC memory card with embedded wireless LAN functionality to meet the SD Memory Card Standard. Previously other SD cards such as Eye-Fi allowed Wi-fi connectivity, but the Eye-Fi could only transmit files from a camera directly to another Wifi device, the FlashAir can receive and transfer by using point to point connection and a router is not needed. The FlashAir can be fully configured thanks to a configuration file located in the SD Card, so that you can select the IP of the SD Card, the wifi security settings such as WEP, WPA, WPA2… and more. The Toshiba FlashAir will be sampled starting […]

Freescale i.MX6 in Tablet PC by First International Computer (FIC)

Back in January 2011, Freescale announced the availability of its new i.MX 6 Processor series based on Cortex A9 with sample delivery at the end of 2011. Freescale has now revealed that First International Computer (FIC) – 大眾電腦 – a Taiwanese company – has adopted Freescale Semiconductor’s i.MX 6 series microprocessors for use in tablet PCs at the 2011 Freescale Technology Forum China on August 30. FIC will use Freescale’s i.MX 6 MPUs in its new line of tablet PCs with a price target sub-200 USD in order to differentiate itself from major competitors. The Freescale i.MX 6 is based on the ARM Cortex-A9 architecture running at up to 1.2 GHz and come in single core (i.MX6 Solo), dual core (i.MX6 Dual) and quad Core I.MX6 Quad). Currently there are no further information on the FIC tablet specifications.

Android NDK revision 6b

Google has just released Android Native Development Kit Revision 6b, the Android SDK that allows developers to reuse C/C++ code. It is a bug fix version without new feature compared to Revision 6. Here’s the Changelog of the most important bug fixes: Fixed the build when APP_ABI=”armeabi x86″ is used for multi-architecture builds. Fixed the location of prebuilt STLport binaries in the NDK release package. A bug in the packaging script placed them in the wrong location. Fixed atexit() usage in shared libraries with the x86standalone toolchain. Fixed make-standalone-toolchain.sh –arch=x86. It used to fail to copy the proper GNU libstdc++ binaries to the right location. Fixed the standalone toolchain linker warnings about missing the definition and size for the __dso_handle symbol (ARM only). Fixed the inclusion order of $(SYSROOT)/usr/include for x86 builds. See the bug for more information. Fixed the definitions of ptrdiff_t and size_t in x86-specific systems when they […]

Wyse Announced Two Linux Thin clients: Z50S and Z50D

Wyse Technology announced that its fastest thin clients ever, the Z90D7 and Z90DW are now shipping at VMworld 2011. You can have a look at AMD Embedded G-Series mini-PC, motherboard and thin client for details about the devices. In addition, Wyse also introduced two new Linux-based members of its Z class family – the Wyse Z50S and Wyse Z50D. Both thin clients run Wyse Enhanced SUSE Linux Enterprise. The press release also indicated that “the Z50 thin clients are built on the same exact advanced single and dual core processor hardware platform as the Wyse Z90 thin clients, the upcoming Linux-based Wyse Z50 promises more of the same industry leading power and capability on an enterprise-class Linux operating system”. Wyse did not provide further details but based on the statement above, we can probably safely assume that Z50S will use the single core AMD G-T52R and the Z50D will be […]
