From 664c869f7749da96bbea7307beb043dfe52593c5 Mon Sep 17 00:00:00 2001 From: Kevin O'Connor Date: Sun, 28 Jul 2019 23:23:18 -0400 Subject: lib: Remove unused stm32f1 "hal" code Now that the stm32f1 code has been merged into the stm32 code, there is no longer a need to use the upstream stm32f1 "hal" code.

Card support - for three different databus modes: 1-bit (default), 4-bit and 8-bit - (+) Full compatibility with previous versions of MultiMedia Cards (forward compatibility) - (+) Full compliance with SD Memory Card Specifications Version 2.0 - (+) Full compliance with SD I/O Card Specification Version 2.0: card support for two - different data bus modes: 1-bit (default) and 4-bit - (+) Full support of the CE-ATA features (full compliance with CE-ATA digital protocol - Rev1.1) - (+) Data transfer up to 48 MHz for the 8 bit mode - (+) Data and command output enable signals to control external bidirectional drivers - - ##### How to use this driver ##### - ============================================================================== - [..] - This driver is a considered as a driver of service for external devices drivers - that interfaces with the SDMMC peripheral. - According to the device used (SD card/ MMC card / SDMMC card ...), a set of APIs - is used in the device's driver to perform SDMMC operations and functionalities. - - This driver is almost transparent for the final user, it is only used to implement other - functionalities of the external device. - - [..] - (+) The SDMMC clock (SDMMCCLK = 48 MHz) is coming from a specific output (MSI, PLLUSB1CLK, - PLLUSB2CLK). Before start working with SDMMC peripheral make sure that the - PLL is well configured. - The SDMMC peripheral uses two clock signals: - (++) SDMMC adapter clock (SDMMCCLK = 48 MHz) - (++) APB2 bus clock (PCLK2) - - -@@- PCLK2 and SDMMC_CK clock frequencies must respect the following condition: - Frequency(PCLK2) >= (3 / 8 x Frequency(SDMMC_CK)) - - (+) Enable/Disable peripheral clock using RCC peripheral macros related to SDMMC - peripheral. - - (+) Enable the Power ON State using the SDIO_PowerState_ON() - function and disable it using the function SDIO_PowerState_OFF(). - - (+) Enable/Disable the clock using the __SDIO_ENABLE()/__SDIO_DISABLE() macros. - - (+) Enable/Disable the peripheral interrupts using the macros __SDIO_ENABLE_IT() - and __SDIO_DISABLE_IT() if you need to use interrupt mode. - - (+) When using the DMA mode - (++) Configure the DMA in the MSP layer of the external device - (++) Active the needed channel Request - (++) Enable the DMA using __SDIO_DMA_ENABLE() macro or Disable it using the macro - __SDIO_DMA_DISABLE(). - - (+) To control the CPSM (Command Path State Machine) and send - commands to the card use the SDIO_SendCommand(), - SDIO_GetCommandResponse() and SDIO_GetResponse() functions. First, user has - to fill the command structure (pointer to SDIO_CmdInitTypeDef) according - to the selected command to be sent. - The parameters that should be filled are: - (++) Command Argument - (++) Command Index - (++) Command Response type - (++) Command Wait - (++) CPSM Status (Enable or Disable). - - -@@- To check if the command is well received, read the SDIO_CMDRESP - register using the SDIO_GetCommandResponse(). - The SDMMC responses registers (SDIO_RESP1 to SDIO_RESP2), use the - SDIO_GetResponse() function. - - (+) To control the DPSM (Data Path State Machine) and send/receive - data to/from the card use the SDIO_DataConfig(), SDIO_GetDataCounter(), - SDIO_ReadFIFO(), SDIO_WriteFIFO() and SDIO_GetFIFOCount() functions. - - *** Read Operations *** - ======================= - [..] - (#) First, user has to fill the data structure (pointer to - SDIO_DataInitTypeDef) according to the selected data type to be received. - The parameters that should be filled are: - (++) Data TimeOut - (++) Data Length - (++) Data Block size - (++) Data Transfer direction: should be from card (To SDMMC) - (++) Data Transfer mode - (++) DPSM Status (Enable or Disable) - - (#) Configure the SDMMC resources to receive the data from the card - according to selected transfer mode (Refer to Step 8, 9 and 10). - - (#) Send the selected Read command (refer to step 11). - - (#) Use the SDIO flags/interrupts to check the transfer status. - - *** Write Operations *** - ======================== - [..] - (#) First, user has to fill the data structure (pointer to - SDIO_DataInitTypeDef) according to the selected data type to be received. - The parameters that should be filled are: - (++) Data TimeOut - (++) Data Length - (++) Data Block size - (++) Data Transfer direction: should be to card (To CARD) - (++) Data Transfer mode - (++) DPSM Status (Enable or Disable) - - (#) Configure the SDMMC resources to send the data to the card according to - selected transfer mode. - - (#) Send the selected Write command. - - (#) Use the SDIO flags/interrupts to check the transfer status. - - *** Command management operations *** - ===================================== - [..] - (#) The commands used for Read/Write/Erase operations are managed in - separate functions. - Each function allows to send the needed command with the related argument, - then check the response. - By the same approach, you could implement a command and check the response. - - @endverbatim - ****************************************************************************** - * @attention - * - *
