|

* FEE_DENSITY_PAGES # Total number of pages to use for eeprom simulation (Compact + Write log)
|
||||
* FEE_DENSITY_BYTES # Size of simulated eeprom. (Defaults to half the space allocated by FEE_DENSITY_PAGES)

* FEE_PAGE_COUNT # Total number of pages to use for eeprom simulation (Compact + Write log)
|

* FEE_DENSITY_BYTES # Size of simulated eeprom. (Defaults to half the space allocated by FEE_PAGE_COUNT)
|
||||
* NOTE: The current implementation does not include page swapping,
|
||||
* and FEE_DENSITY_BYTES will consume that amount of RAM as a cached view of actual EEPROM contents.
|
||||
*
|
||||
* The maximum size of FEE_DENSITY_BYTES is currently 16384. The write log size equals
|
||||
* FEE_DENSITY_PAGES * FEE_PAGE_SIZE - FEE_DENSITY_BYTES.
|
||||
* FEE_PAGE_COUNT * FEE_PAGE_SIZE - FEE_DENSITY_BYTES.
|
||||
* The larger the write log, the less frequently the compacted area needs to be rewritten.
