sahilmgandhi 18:6a4db94011d3 13 ##### How to use this driver #####
sahilmgandhi 18:6a4db94011d3 14 ===============================================================================
sahilmgandhi 18:6a4db94011d3 15 [..]
sahilmgandhi 18:6a4db94011d3 16 This driver is a generic layered driver which contains a set of APIs used to
sahilmgandhi 18:6a4db94011d3 17 control PCCARD/compact flash memories. It uses the FSMC layer functions
sahilmgandhi 18:6a4db94011d3 18 to interface with PCCARD devices. This driver is used for:
sahilmgandhi 18:6a4db94011d3 19
sahilmgandhi 18:6a4db94011d3 20 (+) PCCARD/Compact Flash memory configuration sequence using the function
sahilmgandhi 18:6a4db94011d3 21 HAL_PCCARD_Init()/HAL_CF_Init() with control and timing parameters for
sahilmgandhi 18:6a4db94011d3 22 both common and attribute spaces.
sahilmgandhi 18:6a4db94011d3 23
sahilmgandhi 18:6a4db94011d3 24 (+) Read PCCARD/Compact Flash memory maker and device IDs using the function
sahilmgandhi 18:6a4db94011d3 25 HAL_PCCARD_Read_ID()/HAL_CF_Read_ID(). The read information is stored in
sahilmgandhi 18:6a4db94011d3 26 the CompactFlash_ID structure declared by the function caller.
sahilmgandhi 18:6a4db94011d3 27
sahilmgandhi 18:6a4db94011d3 28 (+) Access PCCARD/Compact Flash memory by read/write operations using the functions
sahilmgandhi 18:6a4db94011d3 29 HAL_PCCARD_Read_Sector()/ HAL_PCCARD_Write_Sector() -
sahilmgandhi 18:6a4db94011d3 30 HAL_CF_Read_Sector()/HAL_CF_Write_Sector(), to read/write sector.
sahilmgandhi 18:6a4db94011d3 31
sahilmgandhi 18:6a4db94011d3 32 (+) Perform PCCARD/Compact Flash Reset chip operation using the function
sahilmgandhi 18:6a4db94011d3 33 HAL_PCCARD_Reset()/HAL_CF_Reset.
sahilmgandhi 18:6a4db94011d3 34
sahilmgandhi 18:6a4db94011d3 35 (+) Perform PCCARD/Compact Flash erase sector operation using the function
sahilmgandhi 18:6a4db94011d3 36 HAL_PCCARD_Erase_Sector()/HAL_CF_Erase_Sector.
sahilmgandhi 18:6a4db94011d3 37
sahilmgandhi 18:6a4db94011d3 38 (+) Read the PCCARD/Compact Flash status operation using the function
sahilmgandhi 18:6a4db94011d3 39 HAL_PCCARD_ReadStatus()/HAL_CF_ReadStatus().
sahilmgandhi 18:6a4db94011d3 40
sahilmgandhi 18:6a4db94011d3 41 (+) You can monitor the PCCARD/Compact Flash device HAL state by calling
sahilmgandhi 18:6a4db94011d3 42 the function HAL_PCCARD_GetState()/HAL_CF_GetState()
sahilmgandhi 18:6a4db94011d3 43
sahilmgandhi 18:6a4db94011d3 44 [..]
sahilmgandhi 18:6a4db94011d3 45 (@) This driver is a set of generic APIs which handle standard PCCARD/compact flash
sahilmgandhi 18:6a4db94011d3 46 operations. If a PCCARD/Compact Flash device contains different operations
sahilmgandhi 18:6a4db94011d3 47 and/or implementations, it should be implemented separately.
