| * @brief PCCARD HAL module driver. |
| * This file provides a generic firmware to drive PCCARD memories mounted |
| * as external device. |
| * |
| @verbatim |
| =============================================================================== |
| ##### How to use this driver ##### |
| =============================================================================== |
| [..] |
| This driver is a generic layered driver which contains a set of APIs used to |
| control PCCARD/compact flash memories. It uses the FSMC layer functions |
| to interface with PCCARD devices. This driver is used for: |
| |
| (+) PCCARD/Compact Flash memory configuration sequence using the function |
| HAL_PCCARD_Init()/HAL_CF_Init() with control and timing parameters for |
| both common and attribute spaces. |
| |
| (+) Read PCCARD/Compact Flash memory maker and device IDs using the function |
| HAL_PCCARD_Read_ID()/HAL_CF_Read_ID(). The read information is stored in |
| the CompactFlash_ID structure declared by the function caller. |
| |
| (+) Access PCCARD/Compact Flash memory by read/write operations using the functions |
| HAL_PCCARD_Read_Sector()/ HAL_PCCARD_Write_Sector() - |
| HAL_CF_Read_Sector()/HAL_CF_Write_Sector(), to read/write sector. |
| |
| (+) Perform PCCARD/Compact Flash Reset chip operation using the function |
| HAL_PCCARD_Reset()/HAL_CF_Reset. |
| |
| (+) Perform PCCARD/Compact Flash erase sector operation using the function |
| HAL_PCCARD_Erase_Sector()/HAL_CF_Erase_Sector. |
| |
| (+) Read the PCCARD/Compact Flash status operation using the function |
| HAL_PCCARD_ReadStatus()/HAL_CF_ReadStatus(). |
| |
| (+) You can monitor the PCCARD/Compact Flash device HAL state by calling |
| the function HAL_PCCARD_GetState()/HAL_CF_GetState() |
| |
| [..] |
| (@) This driver is a set of generic APIs which handle standard PCCARD/compact flash |
| operations. If a PCCARD/Compact Flash device contains different operations |
| and/or implementations, it should be implemented separately. |
| |
| *** Callback registration *** |
| ============================================= |
| [..] |
| The compilation define USE_HAL_PCCARD_REGISTER_CALLBACKS when set to 1 |
| allows the user to configure dynamically the driver callbacks. |
| |
| Use Functions @ref HAL_PCCARD_RegisterCallback() to register a user callback, |
| it allows to register following callbacks: |
| (+) MspInitCallback : PCCARD MspInit. |
| (+) MspDeInitCallback : PCCARD MspDeInit. |
| This function takes as parameters the HAL peripheral handle, the Callback ID |
| and a pointer to the user callback function. |
| |
| Use function @ref HAL_PCCARD_UnRegisterCallback() to reset a callback to the default |
| weak (surcharged) function. It allows to reset following callbacks: |
| (+) MspInitCallback : PCCARD MspInit. |
| (+) MspDeInitCallback : PCCARD MspDeInit. |
| This function) takes as parameters the HAL peripheral handle and the Callback ID. |
| |
| By default, after the @ref HAL_PCCARD_Init and if the state is HAL_PCCARD_STATE_RESET |
| all callbacks are reset to the corresponding legacy weak (surcharged) functions. |
| Exception done for MspInit and MspDeInit callbacks that are respectively |
| reset to the legacy weak (surcharged) functions in the @ref HAL_PCCARD_Init |
| and @ref HAL_PCCARD_DeInit only when these callbacks are null (not registered beforehand). |
| If not, MspInit or MspDeInit are not null, the @ref HAL_PCCARD_Init and @ref HAL_PCCARD_DeInit |
| keep and use the user MspInit/MspDeInit callbacks (registered beforehand) |
| |
| Callbacks can be registered/unregistered in READY state only. |
| Exception done for MspInit/MspDeInit callbacks that can be registered/unregistered |
| in READY or RESET state, thus registered (user) MspInit/DeInit callbacks can be used |
| during the Init/DeInit. |
| In that case first register the MspInit/MspDeInit user callbacks |
| using @ref HAL_PCCARD_RegisterCallback before calling @ref HAL_PCCARD_DeInit |
| or @ref HAL_PCCARD_Init function. |
| |
| When The compilation define USE_HAL_PCCARD_REGISTER_CALLBACKS is set to 0 or |
| not defined, the callback registering feature is not available |
| and weak (surcharged) callbacks are used. |
