Detailed Description
template<nvm_size_t PROVISION = 0, uint8_t LAST_SLOT = 0>
class SlotNVM32CRC< PROVISION, LAST_SLOT >
SlotNVM with 32 bytes per cluster protected with CRC.
26 bytes per cluster or 81,3% can be used for user data. Random function for wear leveling is random() so do not forget to call srandom() or randomSeed().
- Template Parameters
-
PROVISION Bytes that must always be free to ensure that data can safely be rewritten. If your slot data do not exceed this limit is can always be rewritten without deleting other data before. This value is rounded to next multiple of user data of a cluster. LAST_SLOT Number of last usable slot. Maximum value is 250. 0 mean number is equal to count of available cluster.
