The Intel HEX file format is a widely used ASCII text file format for conveying binary information, primarily used for programming microcontrollers, EPROMs, and other programmable devices. It represents binary data in a human-readable hexadecimal format. Each line in an Intel HEX file represents a record, which contains information such as the starting address, record type, byte count, data bytes, and a checksum. The record types indicate the purpose of the data, such as data records, end-of-file records, extended segment address records, and start address records. This format is crucial for transferring compiled code from a development environment to the target hardware. The checksum ensures data integrity during transmission. Intel HEX files are essential in embedded systems development, providing a standardized way to represent and transfer executable code to microcontrollers and other programmable devices. They are preferred due to their simplicity, readability, and widespread support across various programming tools and hardware platforms. The format allows for efficient storage and transmission of binary data, making it a cornerstone of embedded software development workflows.
