App note: Microchip Ni-MH battery charger application library
Our app note for the day: The Battery Charger Application Library easily allows adding battery charging functionality to portable applications. Since it is very compact (uses less than 2k words of program space and less than 128 bytes of RAM) it fits on small, cost-effective parts like the 14-pin PIC16F616. The library is available in […]
Radare2 open source reverse engineering software
Radare2 is an open source tool to disassemble, debug, analyze and manipulate binary files. Edd at Canthack has posted a detailed example demonstrating use of Radare2 to reverse shellcode. You may also want to check out the Radare talks and docs pages for more information on this tool. They have a 152 page book covering […]
3 wire DLG2416 CPLD display controller
Alan posted this project at FromOrbit demonstrating how to implement three wire control of a DLG2416 display using a CPLD. The chip he chose was the Xilinx XC9536 which is the 36 macrocell version of the XC9572 CPLD found in our CPLD Development Board, so this can be implemented on our board with room to […]
Read an Arduino via REST and upload value to Thingspeak
Thingspeak bills itself as “an open application platform designed to enable meaninful connections between people and things.” The graphic above demonstrates how dynamic temperature level readings can be made available on the internet via Thingspeak. In working with the Thingspeak API Sirleech has developed code he calls RestduinoThingspeak. It’s a Python script to read a […]
EasyMSP 0.8.3 Beta1 released
Matthew Burmeister writes to inform us of the release of version 0.8.3 Beta1 of EasyMSP. As covered in our previous post, EasyMSP allows MSP430 users to run Arduino code with few modifications.
Pen testers build a better mousetrap
Netragard is a security company that provides anti-hacking services (penetration testing, vulnerability assessments, web application security testing, etc) to its customers via the realistic reproduction of threats. In a recent assignment the client specified that the test could not use social engineering or physically access client facilities. With their work cut out for them, Netragard […]
PropForth IDE for the Parallax Propeller
PropForth is a fully interactive development environment which runs on the Parallax Propeller allowing you to program the chip interactively in Forth using a PC serial terminal program. Their latest code release is Version 4.5. According to their project description: Propforth 4.5 introduces standardized interfaces (cog, serial, ethernet, etc), SD support (thanks caskaz), completed EEPROM […]
The Verbalizer: open source dev board for Google’s voice search
BreakfastNY has posted details on how to build The Verbalizer: your own open source Arduino based microphone dev board for use with Google’s Voice Search for Desktop. They write: With Google announcing the launch of Voice Search for desktop, we couldn’t help thinking that there was even more fun to be had with talking to […]
IR decoding using ATtiny2313
This article from Radosław Kwiecień’s website shows how to decode RC5 IR signals from a remote control using the 16-bit Timer1 and INT0 external interrupt input in the ATtiny2313 Atmel AVR device. All code in assembly in available in a compressed file.
Simple LaunchPad DAC
NJC’s MSP430 LaunchPad Blog presents this short tutorial on using DAC with the LaunchPad. He writes: This post will show you how to generate a periodic analog signal using the LaunchPad and the MSP430G2231. For the sake of simplicity, I stuck to the default DCO value. This will allow us to generate a very clean […]
Kinect for Windows SDK beta released
Microsoft has released the beta of their Kinect for Windows SDK. The Kinect for Windows SDK beta is a programming toolkit for application developers. It enables the academic and enthusiast communities easy access to the capabilities offered by the Microsoft Kinect device connected to computers running the Windows 7 operating system. The Kinect for Windows […]
EasyMSP 0.8.2 Beta2 released
MattTheGeek has released his early project code for EasyMSP, which allows MSP430 users to run Arduino code with few modification, thanks to EasyMSP’s AFI, or Arduino Function Interface. The purpose of this project is to create a user friendly dev environment for MSP430 MCUs, seeking to accommodate both beginners and advanced users by providing the […]
Update on Arduino imaging – Processing sketch + video
Earlier this week we posted about Carlos Agell’s project which allows the acquisition of analog camera images by an Arduino. Carlos has updated this project for use with a Processing sketch instead of the costly LabVIEW required in the original design. Here’s the link to his compressed file containing the Arduino and Processing sketches, LabVIEW […]
Processing 1.5 provides Android support
Processing version 1.5 is available for download. In addition to support for traditional desktop/web development, this release also includes an Android development mode. This should make Android development easier than using the Android SDK. For everything you need to know to start developing in Processing for Android, see the their Android Wiki page.
Polycode
Polycode is a cross-platform framework for creative code. You can use it as a C++ API or as a standalone scripting language to get easy and simple access to accelerated 2D and 3D graphics, hardware shaders, sound and network programming, physics engines and more. The core Polycode API is written in C++ and can be […]
Image acquisition from an analog camera using Arduino
Carlos Agell of Hacking Electronics has developed this project which allows the acquisition of analog camera images by an Arduino. He uses an Arduino, Nootropic’s video experimenter shield, 1% resistors and a potentiometer. This hardware captures a 128×96 monochrome image and sends it back via serial to a PC where it can be viewed using […]
