Bit Viewer – version 1.1.4263 (first official release) September 4, 2011at00:38
I recently started doing a lot of low level programming in C. I wrote a small desktop application to help with conversions between hexadecimal, decimal and binary formats. It also allows for some simple visualization of the bit-pattern. The program is released under GPL2 and source code as well as executable can be downloaded from the Bit Viewer project page.
