The Intel HEX file format is a widely used ASCII text file format for conveying binary data, primarily for programming microcontrollers, EPROMs, and other programmable devices. It represents binary data in a human-readable hexadecimal format. Each line in a HEX file represents a record, which contains information such as the starting address for the data, the number of data bytes, the actual data bytes in hexadecimal representation, and a checksum to ensure data integrity. The format is designed to be simple to parse and generate, making it suitable for transferring data between different development tools and programming devices. HEX files are commonly used in embedded systems development for storing firmware, configuration data, and other types of binary information. The format allows for specifying memory addresses, enabling precise placement of data within the target device's memory space. Different record types within the HEX file allow for specifying the start address, end of file, and extended address information, supporting memory spaces larger than 64KB. The checksum ensures that the data has not been corrupted during transmission or storage. The simplicity and widespread support make the Intel HEX format a reliable choice for programming embedded systems.
