Understanding data types is especially important if you wish to use serial communication to send data to your Arduino and have the ATmega328 act on this data. HexCmp is a program, which combines together the features of a binary file comparison application and a convenient hex editor. The program will help you to compare files in binary format, at the same time serving as a hex editor that will edit files.
