mbed_official 235:685d5f11838f 13 ##### How to use this driver #####
mbed_official 235:685d5f11838f 14 ===============================================================================
mbed_official 235:685d5f11838f 15 [..]
mbed_official 235:685d5f11838f 16 This driver is a generic layered driver which contains a set of APIs used to
mbed_official 235:685d5f11838f 17 control PCCARD/compact flash memories. It uses the FMC/FSMC layer functions
mbed_official 235:685d5f11838f 18 to interface with PCCARD devices. This driver is used for:
mbed_official 235:685d5f11838f 19
mbed_official 235:685d5f11838f 20 (+) PCCARD/compact flash memory configuration sequence using the function
mbed_official 235:685d5f11838f 21 HAL_PCCARD_Init() with control and timing parameters for both common and
mbed_official 235:685d5f11838f 22 attribute spaces.
mbed_official 235:685d5f11838f 23
mbed_official 235:685d5f11838f 24 (+) Read PCCARD/compact flash memory maker and device IDs using the function
mbed_official 235:685d5f11838f 25 HAL_CF_Read_ID(). The read information is stored in the CompactFlash_ID
mbed_official 235:685d5f11838f 26 structure declared by the function caller.
mbed_official 235:685d5f11838f 27
mbed_official 235:685d5f11838f 28 (+) Access PCCARD/compact flash memory by read/write operations using the functions
mbed_official 235:685d5f11838f 29 HAL_CF_Read_Sector()/HAL_CF_Write_Sector(), to read/write sector.
mbed_official 235:685d5f11838f 30
mbed_official 235:685d5f11838f 31 (+) Perform PCCARD/compact flash Reset chip operation using the function HAL_CF_Reset().
mbed_official 235:685d5f11838f 32
mbed_official 235:685d5f11838f 33 (+) Perform PCCARD/compact flash erase sector operation using the function
mbed_official 235:685d5f11838f 34 HAL_CF_Erase_Sector().
mbed_official 235:685d5f11838f 35
mbed_official 235:685d5f11838f 36 (+) Read the PCCARD/compact flash status operation using the function HAL_CF_ReadStatus().
mbed_official 235:685d5f11838f 37
mbed_official 235:685d5f11838f 38 (+) You can monitor the PCCARD/compact flash device HAL state by calling the function
mbed_official 235:685d5f11838f 39 HAL_PCCARD_GetState()
mbed_official 235:685d5f11838f 40
mbed_official 235:685d5f11838f 41 [..]
mbed_official 235:685d5f11838f 42 (@) This driver is a set of generic APIs which handle standard PCCARD/compact flash
mbed_official 235:685d5f11838f 43 operations. If a PCCARD/compact flash device contains different operations
mbed_official 235:685d5f11838f 44 and/or implementations, it should be implemented separately.
