TI SimpleLink GPS CC4000 Enables GPS For MCUs

Yesterday, Texas Instruments unveiled the SimpleLink GPS CC4000, a GPS self-contained module that can be interfaced with any MCU or MPU having a UART interface. Due to limited resources of microcontrollers, several GPS features have been implemented in hardware such as the push-to-fix function which can simply be controlled by the MCU via a GPIO to receive National Marena Electronics Association (NMEA) strings containing location, time and velocity information. TI Simplelink GPS CC4000 enables GPS-based applications such as asset tracking, industrial M2M, sports and fitness, and precision timing. It can deliver better than 2.5 meter accuracy and provides pulse-per-second output functions to provide precise location and timing data. It can also automatically reuse previously decoded satellite information thanks to its “watchful-eye” feature in order to deliver fast time to first fix (TTFF) and optimize power consumption. Here are SimpleLink GPS CC4000 key features: Driverless, fully integrated GPS solution which requires […]

Cross-compiling the ARM Linux Kernel in Ubuntu 12.04 LTS

Yesterday I installed Ubuntu 12.04 ‘Precise’ Beta 1 in Virtual Box to give it a try (I could not manage to have HUD working btw), and today, I’ve noticed an article entitled “Ubuntu 12.04 ‘precise’ and cross compilation of ARM kernels” explaining how to build Linaro ARM kernel in Ubuntu 12.04. So I’ve decided to give it a try, especially it seems straightforward. I followed the instructions in the aforementioned link, it basically worked except I had to install dpkg-dev package that also installed the build essentials (gcc, g++, etc…) and use sudo for some commands. You’ll notice the name change for the ARM gcc toolchain as it now uses hard-float by default which seems to provide quite a boost in performance for the Pandaboard. Here are the steps I followed: Install the ARM GCC cross compiler and the development package of dpkg:

sudo apt-get install gcc-arm-linux-gnueabihf dpkg-dev

1	sudo apt-get install gcc-arm-linux-gnueabihf dpkg-dev

Retrieve the kernel source:

apt-get source linux-source-3.2.0

1	apt-get source linux-source-3.2.0

Install […]

FSLBOT: Freescale (Dancing) Robot Kit

Freescale unveiled the FSLBOT prototype last year (and I missed it!), and today, the company has announced further improvements to the Freescale Tower System mechatronics robot and board, a bipedal robot and development board that allows designers to write software for a variety of sensor applications while making a robot walk and respond to touch, motion, vibration, tilt and other external stimuli. The new version of the robot uses a new programming language based on StickOS, has wireless capabilities and adds an Xtrinsic MAG3110 magnetometer. This robot has been designed with the collaboration of StickOS and CPUStick.com with the goal “to create a tool that would enable casual users and consumers of technology to become creators and innovators”. The Freescale FSLBOT Robot Kit comes with the following: Freescale Tower System mechatronics board powered by a 32-bit ColdFire MCU with 64K of RAM and 512K of flash. Leg mechanics and associated […]

Glark, an alternative to Grep

grep is a very useful tool to search or filter strings in order to look for files, parse useful info in log files and more. glark is an alternative to grep, it has few features that grep does not such as complex expressions, Perl-compatible regular expressions, and excluding binary files. It also has a more fancy way of display results. It is described as follows in the manpage: Similar to “grep”, “glark” offers: Perl-compatible regular expressions, color highlighting of matches, context around matches, complex expressions (“and” and “or”), grep output emulation, and automatic exclusion of non-text files. Its regular expressions should be familiar to persons experienced in Perl, Python, or Ruby. File may also be a list of files in the form of a path. glark is not installed by default. To install it in Debian/Ubuntu/Mint: sudo apt-get install glark It does not appear to be available in Fedora and […]

ARCHOS G9 Tablets Firmware 4.0.5 Released

Two weeks ago, Archos released the first firmware for Archos 80 G9 / 101 G9 and A70B supporting Android 4.0.3 (ICS), so it was likely a new one would soon follow to fix a few bugs. Here’s the ChangeLog: Version 4.0.5 – March 22nd, 2012 Wi-Fi: fix slow throughput and disconnections happening on some access points HDMI: solve no sound or no video output issue on some TVs Bluetooth: make sure Bluetooth does not prevent device suspend VPN: fix VPN connection failing Touchscreen: avoid loss of first finger touch while tapping with second finger The update should be done automatically OTA, but alternatively the firmware can be downloaded at http://update.archos.com/9/gen9/gen9_4.0.5/firmware_archos_it4.aos Jean-Luc Aufranc (CNXSoft)Jean-Luc started CNX Software in 2010 as a part-time endeavor, before quitting his job as a software engineering manager, and starting to write daily news, and reviews full time later in 2011. www.cnx-software.com

Microchip Unveils Wi-Fi Comm Demo Board with 32-bit PIC32 MCU

After TI and Qualcomm, here’s another WiFi solution for MCU aimed at the internet of things (IoT). Yesterday, Microchip Technology announced the Wi-Fi Comm Demo Board, which combines a Microchip 32-bit PIC32 microcontroller (PIC32MX695F512H) with a low-power MRF24WB0MA embedded Wi-Fi radio transceiver module. This small (and cheap) demo board can be used to integrate with existing embedded designs and/or to evaluate Wi-Fi connectivity with a 32-bit MCU. Contrary to TI and Qualcomm, the IP network stack is not implemented in hardware, but Microchip provides a TCP/IP stack that can be freely downloaded at http://www.microchip.com/get/A3VP. This TCP/IP stack includes HTML, DHCP, DNS, IPv4/v6, SSL, etc… (See diagram below) The memory footprint is 28-34 KB depending on the modules used. I could not find details about power consumption, but the company claims their solution can also run with just 2 AAA batteries. Microchip explains that this solution can enable the rapid growth […]
