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. |
