#144567 - Checksums in Intel Hex Files Responding to: ???'s previous message |
The data sheet says the controller sends back the 'X' if you send it a record with a bad checksum. So--on the surface, anyway--it seems like a good thing that you are not getting any X's.
As for calculating the checksums, I think this page (on this very site) tells everything you need to know. -- Russ |
