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