/** ****************************************************************************** * @file stm32f4xx_hal_pccard.c * @author MCD Application Team * @version V1.4.1 * @date 09-October-2015 * @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 FMC/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. @endverbatim ****************************************************************************** * @attention * *
