HS XMODEM is a useful and reliable software library in C that provides a progammer with off-the-shelf support for XMODEM protocol data transfer capability. Support for both Xmodem Sedder and Xmodem Receiver is provided as well as support for 128/1024 packet size and checksum/CRC16.
When user application initlialises HsXmodem library, it provides interface callbacks for the services used by Xmodem protocol module: timer management, serial transmission and reception, memory management, event callbacks. This architecture makes it easy to port Xmodem protocol module to any environment
Xmodem module handles all protocol information flow, error recovery, acknowledgements, timeouts and so on. When it is appropriate to send next block of data Hs Xmodem will get next memory block from user application. Similarly, when data has been received Hs Xmodem module will get the next block of memory from user application to store data into
As a backup or an alternative to TFTP, Xmodem is often used in embedded devices and appliances for the purpose of software or configuration upgrade or retrieval.
Main features:
- Xmodem Sender and Receiver
- 128 and 1024 block size
