Install Git for Windows XP, Windows 7

I’ve used TortoiseCVS and TortoiseSVN under Windows XP. However, nowadays many project are using Git instead. Luckily, there is also TortoiseGIT for that matter. You’ll need to install 2 components: TortoiseGit – Port of TortoiseSVN to TortoiseGIT MSysGit – Git for Windows MSysGit already has a graphical interface, so you would also be able to clone repositories, commit change, etc.. with MSysGit alone. The only reason to install TortoiseGit is if you are used to TortoiseCVS/TortoiseSVN and want to keep the same look and feel. I use the following version for installation on Windows XP: TortoiseGit 1.7.2.0 32-bit Git 1.7.4 First, I installed TortoiseGit with the default parameters (TortoisePlink SSH Client) . Finally, I installed Git by deselecting unnecessary components as shown below. We do not need Quick Launch or Desktop icons as we’ll use TortoiseGit instead. I’ve also disabled Windows Explorer Integration or you’d have two Git options in […]

How to Write and Submit a Linux Kernel Patch

Greg Kroah-Hartman has a very good tutorial about writing and submitting a patch to the Linux kernel. The video is over 1 year old but this is still relevant. The materials for this tutorial are available via git: git clone git://github.com/gregkh/kernel-tutorial.git Alternatively, you can also download a copy of the presentation slides. The actual presentation is divided into 6 parts: git basics (git branch, git clone…) Kernel coding style (Details can be found in Documentation/CodingStyle) Fixing a file (with scripts/checkpatch.pl scripts) Generating a patch (with git -diff) Email the patch (with scripts/get_maintainer.pl and git send-email) Q&A If you want to skip the git basics and kernel coding style parts (although I don’t recommend it), fast forward to 13:33. All patches by in the linux kernel are checked by at least 2 persons. Before submitting a patch, you’ll have to make sure of the following (Checklist): Kernel builds with patch applied […]

What is GENIVI ? A Software Standard for the Automotive Industry

I’ve recently read in the news that a few operating systems had achieved GENIVI compliance. So let’s see what Wikipedia says about the GENIVI Alliance: The GENIVI Alliance was founded on March 2, 2009 by BMW Group, Delphi, GM, Intel, Magneti-Marelli, PSA Peugeot Citroen, Visteon, and Wind River Systems with the goal of establishing a globally competitive, Linux-based operating system, middleware and platform for the automotive in-vehicle infotainment industry. Since then, the alliance has expanded to more than 100 members who are working together to deliver an open and globally consistent software platform based on Linux for use by the whole car industry. So the clear goal here is to have some set of software specifications and standards (Currently GENEVI 1.0) in the automotive industry in order to speed time to market and reduce the cost of developing Infotainment applications. GENIVI comes from a concatenation of Geneva and IVI (In-Vehicle […]

Energy Harvesting Development Kit by Microchip Technology

The XLP 16-bit Energy Harvesting Development Kit is a development platform for realizing energy harvesting applications powered by Microchip nanoWatt XLP PIC MCUs which are suited for low power applications with sleep currents down to 20nA, active mode currents down to 50uA/MHz, code execution efficiency, and multiple wake-up sources. The power for the kit is supplied by Cymbet’s EVAL-08 Solar Energy Harvester which features a solar panel suitable for use with indoor or outdoor light. The XLP kit enables rapid prototyping of low power applications such as RF sensors, temperature/environmental sensors, utility meters, remote controls, security sensors and more. For software development and programming, the kit includes the PICkit 3 programmer/debugger for use with the Microchip’s free MPLAB™ Integrated Development Environment. Microchip also provides XLP 16-bit Energy Harvesting RF Demo Code in C language (The file is a Windows Executable, but it’s just an executable compressed file so it can […]

Texas Instruments TRF7970A NFC Transceiver

Texas Instruments has introduced the TRF7970A NFC Transceiver ” speeds designs with easy-to-configure software that helps developers bring peer-to-peer, ultra-low-power capabilities to more applications”. Here’s an excerpt from the press release: Raising the standard for ultra-low-power near field communication (NFC) devices, Texas Instruments Incorporated (TI) (NYSE: TXN) today announced the industry’s lowest power contactless short-range communication transceiver. Ideal for infrastructure devices, the new TRF7970A extends battery life up to 2 times longer than competitive products, as it provides eight selectable power modes ranging from <1 uA in power-down mode to 120 mA in full-power mode. The transceiver comes with easy-to-configure software to help developers get started quickly. Royalty-free stacks are compatible across a broad range of ultra-low-power MSP microcontrollers. Additionally, developers are able to directly access all control registers, allowing for easy fine-tuning of various parameters for the highest performance in every application. You can also read the complete TRF7970A […]
