low level implementation 1-wire interface

Function Documentation

ds_eraseSector()

uint8_t ds_eraseSector

(

uint32_t

adr_start

)

Parameters

adr_start

index sektora, prvy sektor ma adresu 0, druhy 1, ...

ds_isBusy()

uint8_t ds_isBusy

(

void

)

Vráti stav FLASH pamäti.

Returns

stav. 1 - busy, 0 - available

ram_eraseSector()

uint8_t ram_eraseSector

(

uint32_t

addr_start

)

Parameters

addr_start

index sektora, prvy sektor ma adresu 0, druhy 1, ...

ram_isBusy()

uint8_t ram_isBusy

(

void

)

Vráti stav FLASH pamäti.

Returns

stav. 1 - busy, 0 - available

winbond_init()

uint8_t winbond_init

(

void *

hw_object

)

end IO functions

Inicializacia drivera.

Parameters

hspi	odkaz na rozhranie SPI
GPIOx	port na ktorom je pin pre CS
GPIO_Pin	pin pre funkciu CS

Nacita konstantu vyrobcu, ktora reprezentuje kapacitu cipu. Pozor, toto nie je kapacita.

Vráti stav FLASH pamäti

Returns

stav. 1 - busy, 0 - available

HAL_SPI_Transmit(winbondFlash.spi, winbondFlash.tx_data, 1, 2); HAL_SPIEx_FlushRxFifo(winbondFlash.spi); winbondFlash.tx_data[0]=0xFF;

Skontroluje, ci je sektor prazdny, alebo su tam zapisane nejake data.

Parameters

sector_index

poradie sektora. Sektry su cislovane od 0 do 1023 (0 - 0x3FF)

Skontroluje, ci je oblast pamati prazdna, alebo su tam zapisane nejake data.

Parameters

addr	Adresa pamati
n	velkost kontrolovanej pamati. Velkost pamati musi byt mensia ako 1 sektor, co pre 32Mbit pamat je 4096B.

Return values

MEMORY_EMPTY,MEMORY_NOT_EMPTY,MEMORY_BUSY

(nepodarila sa synchronizacia), MEMORY_ERROR (n > 4096)

Prepis udajov v sektore. Vo funkcii winbond_checkSector sa nacita aktualny obsah sektore, nasledne sa sektor zmaze. V nacitanych datach sa urobia pozadovane zmeny a data sa zapisu naspat do pamate.

Parameters

address	adresa sektora (absolutna adresa)
*buf	data, ktore sa maju zapisat od zaciatku sektora.
n	velkost buffera buf.

Kontrolovaný zápis do pamati. Skontroluje obsah pamati, do ktorej sa zapisuje. Táto funkcia dovoluje postupné zapisovanie aj v rámci jedného sektora.

Parameters

address	adresa pre zápis
buf	buffer, ktorý sa zapíše
n	dĺžka buffera buff

Note

max po4čet bajtov na zápis je 4096

Return values

0

- úspech

Parameters

addr_start

index sektora, prvy sektor ma adresu 0, druhy 1, ...
