(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_PAGE_COUNT * FEE_PAGE_SIZE - FEE_DENSITY_BYTES. - * The larger the write log, the less frequently the compacted area needs to be rewritten. - * - * - * *** General Algorithm *** - * - * During initialization: - * The contents of the Compacted-flash area are loaded and the 1's complement value - * is cached into memory (e.g. 0xFFFF in Flash represents 0x0000 in cache). - * Write log entries are processed until a 0xFFFF is reached. - * Each log entry updates a byte or word in the cache. - * - * During reads: - * EEPROM contents are given back directly from the cache in memory. - * - * During writes: - * The contents of the cache is updated first. - * If the Compacted-flash area corresponding to the write address is unprogrammed, the 1's complement of the value is written directly into Compacted-flash - * Otherwise: - * If the write log is full, erase both the Compacted-flash area and the Write log, then write cached contents to the Compacted-flash area. - * Otherwise a Write log entry is constructed and appended to the next free position in the Write log. - * - * - * *** Write Log Structure *** - * - * Write log entries allow for optimized byte writes to addresses below 128. Writing 0 or 1 words are also optimized when word-aligned. - * - * === WRITE LOG ENTRY FORMATS === - * - * ╔═══ Byte-Entry ══╗ - * ║0XXXXXXX║YYYYYYYY║ - * ║ └──┬──┘║└──┬───┘║ - * ║ Address║ Value ║ - * ╚════════╩════════╝ - * 0 <= Address < 0x80 (128) - * - * ╔ Word-Encoded 0 ╗ - * ║100XXXXXXXXXXXXX║ - * ║ │└─────┬─────┘║ - * ║ │Address >> 1 ║ - * ║ └── Value: 0 ║ - * ╚════════════════╝ - * 0 <= Address <= 0x3FFE (16382) - * - * ╔ Word-Encoded 1 ╗ - * ║101XXXXXXXXXXXXX║ - * ║ │└─────┬─────┘║ - * ║ │Address >> 1 ║ - * ║ └── Value: 1 ║ - * ╚════════════════╝ - * 0 <= Address <= 0x3FFE (16382) - * - * ╔═══ Reserved ═══╗ - * ║110XXXXXXXXXXXXX║ - * ╚════════════════╝ - * - * ╔═══════════ Word-Next ═══════════╗ - * ║111XXXXXXXXXXXXX║YYYYYYYYYYYYYYYY║ - * ║ └─────┬─────┘║└───────┬──────┘║ - * ║(Address-128)>>1║ ~Value ║ - * ╚════════════════╩════════════════╝ - * ( 0 <= Address < 0x0080 (128): Reserved) - * 0x80 <= Address <= 0x3FFE (16382) - * - * Write Log entry ranges: - * 0x0000 ... 0x7FFF - Byte-Entry; address is (Entry & 0x7F00) >> 4; value is (Entry & 0xFF) - * 0x8000 ... 0x9FFF - Word-Encoded 0; address is (Entry & 0x1FFF) << 1; value is 0 - * 0xA000 ... 0xBFFF - Word-Encoded 1; address is (Entry & 0x1FFF) << 1; value is 1 - * 0xC000 ... 0xDFFF - Reserved - * 0xE000 ... 0xFFBF - Word-Next; address is (Entry & 0x1FFF) << 1 + 0x80; value is ~(Next_Entry) - * 0xFFC0 ... 0xFFFE - Reserved - * 0xFFFF - Unprogrammed - * - */ - -#include "eeprom_stm32_defs.h" -#if !defined(FEE_PAGE_SIZE) || !defined(FEE_PAGE_COUNT) || !defined(FEE_MCU_FLASH_SIZE) || !defined(FEE_PAGE_BASE_ADDRESS) -# error "not implemented." -#endif - -/* These bits are used for optimizing encoding of bytes, 0 and 1 */ -#define FEE_WORD_ENCODING 0x8000 -#define FEE_VALUE_NEXT 0x6000 -#define FEE_VALUE_RESERVED 0x4000 -#define FEE_VALUE_ENCODED 0x2000 -#define FEE_BYTE_RANGE 0x80 - -/* Addressable range 16KByte: 0 <-> (0x1FFF << 1) */ -#define FEE_ADDRESS_MAX_SIZE 0x4000 - -/* Flash word value after erase */ -#define FEE_EMPTY_WORD ((uint16_t)0xFFFF) - -/* Size of combined compacted eeprom and write log pages */ -#define FEE_DENSITY_MAX_SIZE (FEE_PAGE_COUNT * FEE_PAGE_SIZE) - -#ifndef FEE_MCU_FLASH_SIZE_IGNORE_CHECK /* *TODO: Get rid of this check */ -# if FEE_DENSITY_MAX_SIZE > (FEE_MCU_FLASH_SIZE * 1024) -# pragma message STR(FEE_DENSITY_MAX_SIZE) " > " STR(FEE_MCU_FLASH_SIZE * 1024) -# error emulated eeprom: FEE_DENSITY_MAX_SIZE is greater than available flash size -# endif -#endif - -/* Size of emulated eeprom */ -#ifdef FEE_DENSITY_BYTES -# if (FEE_DENSITY_BYTES > FEE_DENSITY_MAX_SIZE) -# pragma message STR(FEE_DENSITY_BYTES) " > " STR(FEE_DENSITY_MAX_SIZE) -# error emulated eeprom: FEE_DENSITY_BYTES exceeds FEE_DENSITY_MAX_SIZE -# endif -# if (FEE_DENSITY_BYTES == FEE_DENSITY_MAX_SIZE) -# pragma message STR(FEE_DENSITY_BYTES) " == " STR(FEE_DENSITY_MAX_SIZE) -# warning emulated eeprom: FEE_DENSITY_BYTES leaves no room for a write log.
