22 ##### How to use this driver #####
23 ===============================================================================
24 [..]
25 This driver is a generic layered driver which contains a set of APIs used to
26 control PCCARD/compact flash memories. It uses the FMC layer functions
27 to interface with PCCARD devices. This driver is used for:
28
29 (+) PCCARD/Compact Flash memory configuration sequence using the function
30 HAL_PCCARD_Init()/HAL_CF_Init() with control and timing parameters for
31 both common and attribute spaces.
32
33 (+) Read PCCARD/Compact Flash memory maker and device IDs using the function
34 HAL_PCCARD_Read_ID()/HAL_CF_Read_ID(). The read information is stored in
35 the CompactFlash_ID structure declared by the function caller.
36
37 (+) Access PCCARD/Compact Flash memory by read/write operations using the functions
38 HAL_PCCARD_Read_Sector()/ HAL_PCCARD_Write_Sector() -
39 HAL_CF_Read_Sector()/HAL_CF_Write_Sector(), to read/write sector.
40
41 (+) Perform PCCARD/Compact Flash Reset chip operation using the function
42 HAL_PCCARD_Reset()/HAL_CF_Reset.
43
44 (+) Perform PCCARD/Compact Flash erase sector operation using the function
45 HAL_PCCARD_Erase_Sector()/HAL_CF_Erase_Sector.
46
47 (+) Read the PCCARD/Compact Flash status operation using the function
48 HAL_PCCARD_ReadStatus()/HAL_CF_ReadStatus().
49
50 (+) You can monitor the PCCARD/Compact Flash device HAL state by calling
51 the function HAL_PCCARD_GetState()/HAL_CF_GetState()
52
53 [..]
54 (@) This driver is a set of generic APIs which handle standard PCCARD/compact flash
55 operations. If a PCCARD/Compact Flash device contains different operations
56 and/or implementations, it should be implemented separately.
57
58 *** Callback registration ***
59 =============================================
60 [..]
61 The compilation define USE_HAL_PCCARD_REGISTER_CALLBACKS when set to 1
62 allows the user to configure dynamically the driver callbacks.
63
64 Use Functions HAL_PCCARD_RegisterCallback() to register a user callback,
65 it allows to register following callbacks:
66 (+) MspInitCallback : PCCARD MspInit.
67 (+) MspDeInitCallback : PCCARD MspDeInit.
68 This function takes as parameters the HAL peripheral handle, the Callback ID
69 and a pointer to the user callback function.
70
71 Use function HAL_PCCARD_UnRegisterCallback() to reset a callback to the default
72 weak (surcharged) function. It allows to reset following callbacks:
73 (+) MspInitCallback : PCCARD MspInit.
74 (+) MspDeInitCallback : PCCARD MspDeInit.
75 This function) takes as parameters the HAL peripheral handle and the Callback ID.
76
77 By default, after the HAL_PCCARD_Init and if the state is HAL_PCCARD_STATE_RESET
78 all callbacks are reset to the corresponding legacy weak (surcharged) functions.
79 Exception done for MspInit and MspDeInit callbacks that are respectively
80 reset to the legacy weak (surcharged) functions in the HAL_PCCARD_Init
81 and HAL_PCCARD_DeInit only when these callbacks are null (not registered beforehand).
82 If not, MspInit or MspDeInit are not null, the HAL_PCCARD_Init and HAL_PCCARD_DeInit
83 keep and use the user MspInit/MspDeInit callbacks (registered beforehand)
84
85 Callbacks can be registered/unregistered in READY state only.
86 Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered
87 in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used
88 during the Init/DeInit.
89 In that case first register the MspInit/MspDeInit user callbacks
90 using HAL_PCCARD_RegisterCallback before calling HAL_PCCARD_DeInit
91 or HAL_PCCARD_Init function.
92
93 When The compilation define USE_HAL_PCCARD_REGISTER_CALLBACKS is set to 0 or
94 not defined, the callback registering feature is not available
95 and weak (surcharged) callbacks are used.
