When using the flash space of stm8 to store some data, how can we arrange the data space reasonably to avoid damaging the program code? [Copy link]

Because I don't know which address ranges the program occupies, and the data space I need may take up half of the flash, how should I plan the data space?

STM8 has EEPROM.

This is separate and will not affect the code. A key is required to read and write the EEPROM, and it will not affect the data.

If there is no need to rewrite, you can plan it however you want, as long as there is enough space. If rewriting is required, all data sectors must be independent and cannot share the same sector with the program. If frequent rewriting is required, you need to pay attention to the write cycle life of the sector, and use "balance algorithms" such as cyclic writing. At this time, you must consider the relationship between storage space and data volume, which determines the life.

Reserve a certain amount of space for the code area, and then just change the space of other addresses!
