bogdanm 0:9b334a45a8ff 13 ##### How to use this driver #####
bogdanm 0:9b334a45a8ff 14 ===============================================================================
bogdanm 0:9b334a45a8ff 15 [..]
bogdanm 0:9b334a45a8ff 16 This driver is a generic layered driver which contains a set of APIs used to
bogdanm 0:9b334a45a8ff 17 control PCCARD/compact flash memories. It uses the FSMC/FSMC layer functions
bogdanm 0:9b334a45a8ff 18 to interface with PCCARD devices. This driver is used for:
bogdanm 0:9b334a45a8ff 19
bogdanm 0:9b334a45a8ff 20 (+) PCCARD/compact flash memory configuration sequence using the function
bogdanm 0:9b334a45a8ff 21 HAL_PCCARD_Init() with control and timing parameters for both common and
bogdanm 0:9b334a45a8ff 22 attribute spaces.
bogdanm 0:9b334a45a8ff 23
bogdanm 0:9b334a45a8ff 24 (+) Read PCCARD/compact flash memory maker and device IDs using the function
bogdanm 0:9b334a45a8ff 25 HAL_PCCARD_Read_ID(). The read information is stored in the CompactFlash_ID
bogdanm 0:9b334a45a8ff 26 structure declared by the function caller.
bogdanm 0:9b334a45a8ff 27
bogdanm 0:9b334a45a8ff 28 (+) Access PCCARD/compact flash memory by read/write operations using the functions
bogdanm 0:9b334a45a8ff 29 HAL_PCCARD_Read_Sector()/HAL_PCCARD_Write_Sector(), to read/write sector.
bogdanm 0:9b334a45a8ff 30
bogdanm 0:9b334a45a8ff 31 (+) Perform PCCARD/compact flash Reset chip operation using the function HAL_PCCARD_Reset().
bogdanm 0:9b334a45a8ff 32
bogdanm 0:9b334a45a8ff 33 (+) Perform PCCARD/compact flash erase sector operation using the function
bogdanm 0:9b334a45a8ff 34 HAL_PCCARD_Erase_Sector().
bogdanm 0:9b334a45a8ff 35
bogdanm 0:9b334a45a8ff 36 (+) Read the PCCARD/compact flash status operation using the function HAL_PCCARD_ReadStatus().
bogdanm 0:9b334a45a8ff 37
bogdanm 0:9b334a45a8ff 38 (+) You can monitor the PCCARD/compact flash device HAL state by calling the function
bogdanm 0:9b334a45a8ff 39 HAL_PCCARD_GetState()
bogdanm 0:9b334a45a8ff 40
bogdanm 0:9b334a45a8ff 41 [..]
bogdanm 0:9b334a45a8ff 42 (@) This driver is a set of generic APIs which handle standard PCCARD/compact flash
bogdanm 0:9b334a45a8ff 43 operations. If a PCCARD/compact flash device contains different operations
bogdanm 0:9b334a45a8ff 44 and/or implementations, it should be implemented separately.
