SBrConfigRecord Struct Reference

Description

Brownie configuration record (stored in EEPROM).

This record contains changeable configuration parameters.

The configuration is stored in the EEPROM at address BR_EEPROM_CFG_BASE (see below). On startup, an SRAM copy is made, accessible via 'brConfigRecord'. Hence, changes to the EEPROM only take effect after the next reboot. This is particularly relevant if the device address is changed.

Note: The size of this structure must be equal to BR_EEPROM_CFG_SIZE and a multiple of BR_MEM_BLOCKSIZE. This can be checked by compiling and running 'home2l-brownie2l' (see entry of main() there).
