##### SDMMC peripheral features #####
|
|
==============================================================================
|
|
[..] The SD/SDMMC MMC card host interface (SDMMC) provides an interface between the AHB
|
|
peripheral bus and MultiMedia cards (MMCs), SD memory cards, SDMMC cards and CE-ATA
|
|
devices.
|
|
|
|
[..] The SDMMC features include the following:
|
|
(+) Full compliance with MultiMediaCard System Specification Version 4.51. Card support
|
|
for three different databus modes: 1-bit (default), 4-bit and 8-bit.
|
|
(+) Full compatibility with previous versions of MultiMediaCards (backward compatibility).
|
|
(+) Full compliance with SD memory card specifications version 4.1.
|
|
(SDR104 SDMMC_CK speed limited to maximum allowed IO speed, SPI mode and
|
|
UHS-II mode not supported).
|
|
(+) Full compliance with SDIO card specification version 4.0. Card support
|
|
for two different databus modes: 1-bit (default) and 4-bit.
|
|
(SDR104 SDMMC_CK speed limited to maximum allowed IO speed, SPI mode and
|
|
UHS-II mode not supported).
|
|
(+) Data transfer up to 208 Mbyte/s for the 8 bit mode. (depending maximum allowed IO speed).
|
|
(+) 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 is coming from output of PLL1_Q or PLL2_R.
|
|
Before start working with SDMMC peripheral make sure that the PLL is well configured.
|
|
The SDMMC peripheral uses two clock signals:
|
|
(++) PLL1_Q bus clock (default after reset)
|
|
(++) PLL2_R bus clock
|
|
|
|
(+) Enable/Disable peripheral clock using RCC peripheral macros related to SDMMC
|
|
peripheral.
|
|
|
|
(+) Enable the Power ON State using the SDMMC_PowerState_ON(SDMMCx)
|
|
function and disable it using the function SDMMC_PowerState_OFF(SDMMCx).
|
|
|
|
(+) Enable/Disable the peripheral interrupts using the macros __SDMMC_ENABLE_IT(hSDMMC, IT)
|
|
and __SDMMC_DISABLE_IT(hSDMMC, IT) if you need to use interrupt mode.
|
|
|
|
(+) When using the DMA mode
|
|
(++) Configure the IDMA mode (Single buffer or double)
|
|
(++) Configure the buffer address
|
|
(++) Configure Data Path State Machine
|
|
|
|
(+) To control the CPSM (Command Path State Machine) and send
|
|
commands to the card use the SDMMC_SendCommand(SDMMCx),
|
|
SDMMC_GetCommandResponse() and SDMMC_GetResponse() functions. First, user has
|
|
to fill the command structure (pointer to SDMMC_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 SDMMC_CMDRESP
|
|
register using the SDMMC_GetCommandResponse().
|
|
The SDMMC responses registers (SDMMC_RESP1 to SDMMC_RESP2), use the
|
|
SDMMC_GetResponse() function.
|
|
|
|
(+) To control the DPSM (Data Path State Machine) and send/receive
|
|
data to/from the card use the SDMMC_DataConfig(), SDMMC_GetDataCounter(),
|
|
SDMMC_ReadFIFO(), SDMMC_WriteFIFO() and SDMMC_GetFIFOCount() functions.
|
|
|
|
*** Read Operations ***
|
|
=======================
|
|
[..]
|
|
(#) First, user has to fill the data structure (pointer to
|
|
SDMMC_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 SDMMC flags/interrupts to check the transfer status.
|
|
|
|
*** Write Operations ***
|
|
========================
|
|
[..]
|
|
(#) First, user has to fill the data structure (pointer to
|
|
SDMMC_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 SDMMC 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.
