    Hallo.

    Is there a possibility to let user write/read some data to/from eeprom of st7flite29 from user level? I mean to let the user store a number of groups of parameters for typical objects. There's only a few objects but many parameters for each of them, so this kind of solution seems to be best. So the main question is, if it'possible, how to initialize eeprom for user and how to let him store the grops of data there?

    regards,

    Hi,

    I suppose you don't mean the memory EEPROM of the ST7FLite29 but the flash. There is a mode called the IAP (In Application Programming) where you can program an area of the flash EEPROM with some restrictions.

    For details see chapter 4.3.2 of the manual and some application notes e.g.
