TI SimpleLink Wi-Fi CC3000 Brings WiFi Connectivity to All Devices

Yesterday, Texas Instruments unveiled the SimpleLink product family, a portfolio of wireless connectivity technologies for low-power, low-cost embedded applications, which includes self-contained wireless processors supporting Wi-Fi, ZigBee, 6LoWPAN, and ANT. The most noticeable product is the SimpleLink Wi-Fi CC3000, a self-contained 802.11 (WiFi) network processor, that can be added to any embedded application and provide WiFi connectivity to the Internet of Things. With this solution, you can add WiFi to any device, even those powered by MCUs without operating systems such as dishwashers, toasters, refrigerators, thermostats, and factory automation equipment. I wish they’ll make new version of the MSP430 Chronos Wireless Watch with WiFi connectivity, this would remove the need for the RF Dongle. This solution features TCP, UDP and IP software stacks in the chip, it consumes 0.5% of the resources as compared to traditional Wi-Fi and only requires 6KB Flash and 3KB RAM. The company claims it can be […]

Texas Instruments OMAP 5 Reference Design

Texas Instruments announced it was developing the OMAP 5, the first Cortex A15 processor, in February 2012. This year at CES 2012, Texas Instruments unveiled OMAP 5-based reference design / development platform running Android 4.0.1 to Engadget. Remi El-Ouazzane, VP of OMAP at Texas Instruments, explains: “This is the greatest platform on Earth right now… way ahead of Apple, and it’s the first Cortex-A15 (which runs 2x faster than the Cortex-A9) product on the market. When running two Cortex-A15 chips at 800MHz, it’s more or less the same performance as running two Cortex-A9s at 1.5GHz. You’ll see [commercially available products] ramping up with this stuff in late 2012 or early 2013. We are also running Windows 8 on the latest OMAP; it runs perfectly well, and we’ve been working very closely with Microsoft. We’re working on multiple form factors — tablets, thin-and-lights — and we think ARM is going to […]

Board Bringup: LCD and Display Interfaces – ELCE 2011

Presentation “Board Bringup: LCD and Display Interfaces” by David Anders, Texas Instruments, at Embedded Linux Conference Europe 2011. Board bringup is one of the most under documented aspects of embedded development. This presentation looked at the various display technologies such as DisplayPort, DVI, LVDS, and other LCD interfacing methods with emphasis on how to bringup, debug, and validate them on new hardware. Using a case study, aspects such as interfacing timing, extended display identification data(EDID), and backlight controls have been discussed. Most embedded linux developers at some point in their career will be handed a piece of hardware that is untested. LCD bringup is one of the most challenging assignments for an embedded developer. This presentation intends to provide some core tools and methods for bringup of a new display interface. You can also download the presentation slides Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, […]

TI Unveils Sitara AM335x ARM Series Cortex-A8 Processors

Texas Instruments has just announced the new Sitara AM335X Processors and the low cost Beaglebone development board. The low cost Cortex-A8 SoCs start at 5 US dollars per piece and are aimed at upgrading ARM9 solutions (software compatible) and adding new features such as 3D interfaces and touch screen, high resolution displays with faster performance. Texas Instruments says you could take those new upgraded products to market within 6 months thanks to their inexpensive development board (Beaglebone) and complete SDK. There are six models in the Sitara AM335X series: AM3552: Cortex A8 up to 720 MHz. AM3554: Cortex A8 up to 720 MHz with 3D Graphics (PowerVR SGX GPU). AM3556: Cortex A8 up to 720 MHz with programmable real-time unit (PRU) @ 200 Mhz. AM3557: Cortex A8 up to 720 MHz with PRU @ 200Mhz and EtherCat. AM3558: Cortex A8 up to 720 MHz with 3D Graphics and PRU @ […]

BeagleBone: New 89 USD Beagleboard

The BeagleBone is a low-cost, high-expansion hardware-hacker focused BeagleBoard. It is a bare-bones BeagleBoard that acts as a USB or Ethernet connected expansion companion for your current BeagleBoard and BeagleBoard-xM or works stand-alone. The BeagleBone is smaller than the previous version of BeagleBoards (looks like the business of a credit card) and features TI Sitara™ AM3358 Cortex A8 processor clocked at 700Mhz. The BeagleBone is also able to run a full-featured Linux. Here are the current hardware specifications: TI AM3358 ARM Cortex-A8 @ 700 MHz 256 MB DDR2 RAM Board size: 3.4″ x 2.1″ Shipped with 2GB microSD card with the Angstrom Distribution with node.js and Cloud9 IDE Single cable development environment with built-in FTDI-based serial/JTAG and on-board hub to give the same cable simultaneous access to a USB device port on the target processor Industry standard 3.3V I/Os on the expansion headers with easy-to-use 0.1″ spacing On-chip Ethernet, not […]

Texas Instruments OMAP 4 / OMAP 5 Update at ARM Techcon 2011

Katie Morgan interviews Brian Carlson, OMAP Product Line Manager – TI, at ARM Techcon 2011. They talk about current products using OMAP4 such as the Amazon Kindle Fire, Motorola Bionic, Motorola Razr and Toshiba AT200. Then they discuss about OMAP 5. Brian explains that OMAP 5 is an extension of OMAP 4 so that once you write software for OMAP 4 it will run on OMAP 5, so the transition is very easy. Products using OMAP 5 will start shipping end of 2012, beginning of 2013. They also talked about the new Cortex-A7 and big.LITTLE processing, but it seems there is no formal announcement from TI on the matter, right now. Finally, they showed two demos: an OMAP4 platform streaming 1080p video stream from Netflix and an augmented reality demo where you show a picture to the camera to start a video on the phone.

Yocto Project Release 1.1 Announced

The Linux foundation announced Yocto Project Release 1.1 today. This release codenamed “Edison” and based on Poky 6.0 is the the second release of the project, one year after it was announced in October 2010 to provide developers with greater consistency in the software and tools they’re using across multiple architectures for embedded Linux development. The Yocto Project reached the following milestones during the last year: Alignment of OpenEmbedded technology and the inclusion of OpenEmbedded representation in the Yocto Project governance structure. The projects share a common core that consists of software build recipes and core Linux components that prevent fragmentation and reinforce the OpenEmbedded methodology as an open standard for embedded Linux build systems. Contribution of tools and technologies such as Cross-prelink, EGLIBC, Pseudo, Shoeleather Lab (for automated testing) and Swabber have been contributed from Intel, Mentor Graphics, MontaVista Software and Wind River. Commercial adoption with examples such as […]

ARM Unveils Cortex-A7 and big.LITTLE processing

ARM unveiled the Cortex A7, a new core with higher performance than the Cortex A8 (1.5x) and with 5 times less power consumption. It will be used in conjunction with Cortex-A15 Core and allows big.LITTLE processing where the Cortex A7 (companion core) takes care of the low performance, low power tasks (social network, email, SMS, phone calls) and the Cortex A15 kicks in for high performance tasks such as video processing and gaming. Here’s an excerpt of the Cortex A7 / big.LITTLE processing press release: ARM today announced the ARM® Cortex™-A7 MPCore™ processor – the most energy-efficient application class processor ARM has ever developed, and big.LITTLE processing – a flexible approach that redefines the traditional power and performance relationship. The Cortex-A7 processor builds on the low-power leadership established by the Cortex-A8 processor that is at the heart of many of today’s most popular smartphones. A single Cortex-A7 processor delivers 5x […]
