MediaTek MT8127 SoC to Bring H.265 Video Support to Mid-Range Android Tablets

MediaTek has just announced MT8127, a quad core ARM Cortex A7 processor @ 1.5 GHz with Mali-450MP GPU, that provides hardware support for HEVC (H.265) video playback, and targets “super-mid” range Android tablets. HEVC/H.265 video codec will allow to half the required bandwidth and/or storage for a given quality compared to H.264, or to greatly improve quality at the same bitrate. The latest Mediatek processor will also support 1080p video playback and recording, and up to 13MP cameras, as well as  1920×1200 LCD screen display. As with other Mediatek SoCs,  a Bluetooth 4.0, Wi-Fi, FM receiver and GPS combo-chip can be coupled with MTK8127. The company also claims Miracast and NFC support. The first tablets to integrate this solution will be ALCATEL ONETOUCH PIXI 7 and Cube U25GT, as well as ALCATEL ONETOUCH PIXI 8, which will be launched later this year.

AsiaRF AWM002 Wi-Fi Module and a Tiny IoT Server Kit Get Crowdfunded for $15 and Up

VoCore Wi-Fi module selling for $15 to $20, and it’s corresponding VoCore Dock with Ethernet has been quite popular, and at the time of writing, the project has already received $40,000 in funding with 50 more days to go. But if you’d rather get something for the same price, a few months early, and an already FCC/CE certified and proven module and tiny IoT server, AsiaRF has also launched a crowdfunding campaign for their AWM002 Wi-Fi module running OpenWRT on the same Ralink RT5350 found on the VoCore. as well as AWM002 Tiny Kit which adds Ethernet and USB, and a larger board with easier access to all ports and I/Os. As a reminder, let’s go through AWM002 specifications again: SoC – Mediatek/Ralink RT5350 MIPS 74KEc core @ 360 MHz dual band 802.11n Wi-Fi with data Rate up to 150Mbps, hardware NAT, QoS, TCP/UDP/IP checksum offloading. System Memory – 32 MB Storage […]

$15 Open Source Hardware VoCore Wi-Fi Module Runs OpenWRT (Crowdfunding)

There are already low cost Wi-Fi modules that can be used for the Internet of Things such as AsiaRF AWM002 and Hi-Link HLK-RM04. However, AsiaRF mainly caters to companies, and the Hi-Link module has a limited memory (16MB), which may or may not be an issue depending on your application. VoCore Wi-Fi module could prove to be an interesting option as it is the same $15 to $20 price range, runs OpenWRT with 32 MB RAM, will be open source hardware, and provides up to 20 GPIOs in a tiny (25x25mm) form factor. VoCore Wi-Fi module specifications: SoC – Ralink/Mediatek RT5350 MIPS processor @ 360MHz with dual band 802.11n Wi-Fi with data Rate up to 150Mbps System Memory – 32 MB RAM Storage – 8MB SPI Flash (for firmware) / 16 MB on limited edition Available Signals (Via through holes): 10/100M Ethernet USB UART, I2C, SPI I2S, PCM JTAG Over 20 […]

$15 AsiaRF AWM002 & AWM003 Wi-Fi Modules Run OpenWRT, Expose GPIOs

This week-end I explained how to build a web server that could be used for automation and other Internet of things applications for less than $15 by combining an Arduino Leonardo with ECN18J60 Ethernet module. The hardware itself is cheap, but it may not always be convenient, or cost effective, to wire your house or office with Ethernet cables. One solution is to use Wi-Fi modules such as TI CC3000 evaluation module, an Electric Imp module, or Ariettea G25 + Wi-Fi board, but these usually cost between $30 to $50 in single quantity. AsiaRF AWM002 and AWM003 are low cost 802.11n Wi-Fi modules with access to GPIOs that could be an interesting alternative as they cost $15 + shipping, and even below $10 in quantities. The only difference between the two is that AWM003 supports more RAM (64MB vs 32MB). Here are the specifications for these modules: SoC – Mediatek/Ralink […]

Techniques to Get more Space for Apps in Android

Many devices now have a single internal partition for apps and data on the internal NAND / eMMC flash, but some companies are still providing firmware with the flash partitioned with an “internal storage” partition for apps and systems, and another partition either called “phone storage” or “internal SD card” to order to store data. In the first case, no problem, but in the second, you may have issues where you have plenty of total space, but the device keeps telling you there is no space, leading to error messages such “email service has stopped”,  app updates which can not complete, and app update downloads occurring in loops and draining the battery. I’ve experienced this issue with my phone (ThL W200) which features a mere 0.91 GB internal storage out of an 8GB NAND flash. Internal storage was 0.91 GB (94% full), phone storage 5.73 GB(3% full), and my micro […]

Mediatek MT8639 Wi-Fi Display SoC to Support 802.11ac, NFC

Wi-Fi display technologies such as Miracast and Airplay allow you to conveniently mirror your mobile device on your TV without the needs to connect any cables, and for over about a year we’ve seen Miracast, Airplay, DLNA, and EZcast dongles on the market. In theory, this is all great, but in practice, this is all too often disappointing because of lag, sometimes the video quality is very poor, and sometimes it won’t connect. Mediatek is now working on MT8639 supporting 802.11ac which will hopefully offer a more consistent and enjoyable user experience, if your mobile device also supports 802.11ac. Here are the main features of the chip: ARM Cortex A7 @ 1 GHz Wi-Fi Dual band 2.4Ghz and 5 GHz 802.11 b/g/n/ and 802.11ac Wifi-Direct, Wi-Fi SoftAP, and Wi-Fi Bridge support Optional NFC support Wi-Fi Display – DLNA, Airplay, Miracast, “Windows” mirror Video Output – HDMI 1.4 / MHL 2.0 […]

Mediatek Hotknot is a Low Cost Alternative to NFC for Chinese Phones

NFC first started to be found in phones running Android 2.3 in 2010, and most flagship smartphones integrate NFC. But in China, at least, the story is different with about 10 percent of smartphones enabled with NFC, according to Mediatek. That’s partly why the company has designed Hotknot proximity technology, which is in theory capable of anything NFC does, but comes at a lower cost. Contrary to NFC, Hotknot it does not require RF transceiver and antenna, but instead relies on a new type of capacitor touch driver IC designed for touch screens combined with data from a gravity sensor (G-sensor) to ensures the actual contact, and a proximity sensor (P-sensor) to detects the presence of nearby objects. It’s not clear when the first smartphone with the technology will hit the “e-store”, but HaoJung Li, product marketing manager of MediaTek’s wireless communications business unit, told EETimes, that every MediaTek customer, […]

Mediatek MT6589 Linux Source Code, CyanogenMod 11 Image for Wiko Stairway Smartphone

Mediatek and their customers have still not gotten into the habit of complying with the GPL license, and releasing the relevant source code such as the Linux kernel. There appears to be at least one smartphone, Wiko Stairway, where the Linux kernel has been released, and chrmhoffmann, a members of XDA developers forums, has even released on unofficial CyanogenMod 11 ROM (Android 4.4.2 Kit Kat) for the device. There are three source repositories for the Linux kernel, “android device“, and Android. I’ve only looked into the kernel which is version 3.4.5. Mediatek has apparently messed up the Linux kernel quite a bit, and you’ll have to do some funny things to build the kernel, and all Mediatek options in menuconfig are in a sub-section called “Mediatek Properitary Configuration” (sic.), and it’s not possible to simply go to System Type menu to change the processor type for instance. Let’s get the […]
