bitstring is a pure Python module designed to help make the creation, manipulation and analysis of binary data as simple and natural as possible. BitStrings can be constructed from integers (big and ... [More] little endian), hex, octal, binary, strings or files. They can be sliced, joined, reversed, inserted into, overwritten, etc. with simple functions or slice notation. They can also be read from, searched and replaced, and navigated in, similar to a file or stream. Internally the data is efficiently stored as byte arrays, the module has been optimized for speed, and excellent code coverage is given by over 300 unit tests. It is available for Python 2.4+ and for Python 3. To get updates on new releases you can subscribe to the project on freshmeat. DocumentationThe manual for the bitstring module is available as a PDF. It contains a walk-through of all the features and a complete reference section. You can also view this on the Wiki. ExamplesCreation: >>> a = BitString(bin='00101') >>> b = BitString(a_file_object) >>> c = BitString('0xff, 0b101, 0o65, uint:6=22') >>> d = pack('intle:16, hex=a, 0b1', 100, a='0x34f') >>> e = pack('For full details on the API changes and for earlier changes, see the release notes. There is one version for Python 2.4 / 2.5 / 2.6 (version 1.0.0) and another for Python 3.0 / 3.1 (version 1.0.1). [Less]

This is mloskot's personal workshop dedicated to miscellaneous prototypes and experiments mostly written in C++ programming language.

PySTDF is a Python module that makes it easy to work with STDF (Teradyne's Standard Test Data Format). STDF is a commonly used binary file format in semiconductor test -- automated test equipment ... [More] (ATE) from such vendors as Teradyne, Verigy, LTX, Credence, and others support this format. [Less]

A binary clock in Python

What is STDF?STDF is the standard test data format used by many of the ATE vendors such as Teradyne. It is the file format most likely being created at production line due to its compactness to save ... [More] storage spaces. STDF ResourcesSTDF on Wikipedia STDF Group MotivationIt could be very useful and convinient to directly look into STDF files, and enables more complicated test data analysis framework to be based on this parser. The old solution is to convertion it to another format (such as TSF) and then open such files with another dedicated tool. This, for me is troublesome and lack of the possibility to fully automate data processing and extraction. Another project pystdf is already there for sometime which supports STDF v4 very well. However somehow (possibly due to the limitation of my knowledge) I found pystdf is a bit diffcult to understand and not easy to extend to meet my personal requirements. Thus I developed this brand new STDF parser that supports both STDFv3 and STDFv4. And I also build an automated yield extraction and reporting tool based on this parser which have now totally substituted the old tool we were using. The parser will support both STDF version 3 and STDF version 4. However the STDF version 3 don't have a public available specification (If at all the version 3 spec is unique for all companies). This STDF version 3 parser is based on Infineon STDF version 3 spec (the spec itself has bugs, well it is fixed in this tool) and probably won't fit your company spec on STDF version 3. Current StatusI would say this STDF parser is reliable enough that it has at least processed more than 10K files (all at mid-night when the server load is at minimum level). The previous development history is all in a git repo which makes the current hg repo only a initial commit of the reliable version. Most of the code is very simple and straightforward. LicenseThis project is released under GPLv3. Related ProjectsI learnt especially how to define the kxCn data type from this project: Another Python-Based STDF parser for STDF version 4 Special NoteI have only tested this script in GNU/Linux environment and it works fine. I don't have much knowledge on MS windows system and I'm glad to hear from other people whether this script works on Windows system. [Less]

NIAPIU stand for NIAP(our group name) + Incremental Upgrade. NIAPIU is designed for help people to decrease the bandwidth when software upgrade. It use bsdiff(http://www.daemonology.net/bsdiff/) ... [More] as kernel.bsdiff routinely produces binary patches 50-80% smaller than those produced by Xdelta, and 15% smaller than those produced by RTPatch. In our experience,NIAPIU is VERY useful.Under normal circumstances，it can save more than 90% of the bandwidth. [Less]

Tool to inspect the content of a binary file

Application binary data files are encountered when creating embedded software for EEPROM or Flash programming. There exist various semi-standard formats to store such files, the most popular of ... [More] which are Intel HEX files and Motorola S-files. In addition, some tools store data in plain binary of ASCII hex-pair files. This module supports reading and writing application binary data files in several formats, and converting between them. [Less]
