HEX and S-record files
Text formats that carry a firmware or calibration image with its memory addresses and checksums, used to flash controllers: Intel HEX and Motorola S-record (.s19, .srec, .mot). Their content must match the A2L that describes it.
- Abbreviation
- .hex, .s19
- Also called
- Intel HEX, Motorola S-record, SREC
Example
Data, communication and electronics: an example situation
2500 in a log might mean 25.00 °C, 2.5 V or raw counts. Units and scale must accompany the value.
Read HEX and S-record files alongside A2L file in this context. The ASAM description of a controller’s internal measurement and calibration variables — names, memory addresses, data types and conversions — that tools need to read or tune them over XCP. It is generated with each firmware build and must match it exactly.
Use in Lemonergy

This is a reference concept. No executable Lemonergy block has been verified for this term.
