libsigrokdecode

The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source signal analysis software suite that supports various device types, such as logic analyzers, MSOs, oscilloscopes, multimeters, LCR meters, sound level meters, thermometers, anemometers, light meters, dataloggers ... [More] , function generators, power supplies, GPIB interfaces, and more. libsigrokdecode is a shared library written in C, which provides (streaming) protocol decoding functionality. The protocol decoders are written in Python (>= 3.0). [Less]

jpeg2000

ABSTRACT CECÍLIO, Pablo Lira. A solution for image capture, compression and transmission by using jpeg2000 in an embedded system. 2009. 61f. Trabalho de Conclusão de Curso (Graduação) – Faculdade de Engenharia de Computação, Centro de Ciências Exatas, Ambientais e de Tecnologias ... [More] , Pontifícia Universidade Católica de Campinas, Campinas, 2009. The size of the image handled by a program affects its performance directly: the larger the image, the lower the performance in the same hardware. The system approached by the present monograph is run in an embedded Analog Devices system, which captures, compresses, and sends images to a PC through a connection under the Zigbee protocol. As the wireless transmission of Xbee devices is very slow, the objective of this system is to decrease the time of image transmission through image compression before their transmission takes place. The system was developed in two main modules: the former is run in the embedded system and written in C/C++ and Assembly; the latter is run in a PC and written in C# and SQL. The system that is run in the embedded system captures images through a CDD camera. Next, it compresses them in the JPEG2000 format (whose features are compression speed and small use of computer resources) and sends them through the Zigbee connection (used in the market by several low-cost devices, in addition to being a high scalability protocol). Prototyping was the methodology in use for the development of such system. The system evaluation showed that in spite of images being frequently corrupted during the transmission, a significant decrease of ten seconds in transfer speed was attained because of the compression. Indexing terms: Image compression. Wireless information transfer. Embedded system. Image storage in database. see more details at http://code.google.com/p/jpeg2000/source/browse/trunk/TCC/entregas/TCC2/Monografia_final.pdf The source code is available at: http://code.google.com/p/jpeg2000/source/browse/trunk/TCC/ This project will use - jpeg2000 for image encoding - NSC/PAL analogic camera for image capture - Ez-kitLite evaluation board with bf533 processor as main board for image processing and image transmission - Xbee for image transmission working in 115200bps [Less]

uarttester

This project aims to test the UART functionality of your platform running any flavor of Microsoft Windows. It has a simple GUI where you configure the parameters and select what type of test you want to run. This project stems out of our requirement to frequently test our UART settings and physical ... [More] connections on new platforms and Windows flavors. Since this project is completely written using win32 API, it should be portable across different OS flavors, with just one or two #define changes. Suggestions, Criticism, Compliments and Volunteers are welcome. [Less]
