Frequently Asked Questions for sd-reader
|
||||
========================================
|
||||
|
||||
General
|
||||
-------
|
||||
|
||||
Q: Which cards are supported?
|
||||
A: All MMC/SD/SDHC/miniSD/microSD/microSDHC should work, although not all variants have been tested.
|
||||
Some very old (low capacity) cards might be broken as well. Cards with a capacity of 16 MB or
|
||||
less are usually formatted with FAT12, so these are supported in raw mode only, if at all.
|
||||
|
||||
Q: What data rates can I expect?
|
||||
A: See the benchmark page on the homepage.
|
||||
http://www.roland-riegel.de/sd-reader/benchmarks/
|
||||
|
||||
Q: Are there boards available for purchase?
|
||||
A: No.
|
||||
|
||||
Hardware
|
||||
--------
|
||||
|
||||
Q: Where can I find the schematic?
|
||||
A: Get it on the homepage.
|
||||
http://www.roland-riegel.de/sd-reader/sd-reader_circuit_latest.zip
|
||||
|
||||
Q: What if my card socket has no Card-Detect and/or Card-Lock switches?
|
||||
A: Change sd_raw_config.h such that it looks like
|
||||
|
||||
#define configure_pin_available() /* nothing */
|
||||
#define configure_pin_locked() /* nothing */
|
||||
|
||||
#define get_pin_available() 0
|
||||
#define get_pin_locked() 1
|
||||
|
||||
Q: All attempts to write to the card fail, although reading works. What's the problem?
|
||||
A: Enable write support within sd_raw_config.h. And probably, your card socket has no Card-lock
|
||||
detection (see question above).
|
||||
|
||||
Q: The card initialization fails. What can I do?
|
||||
A: Usually this is some kind of hardware problem.
|
||||
* Check the physical connections.
|
||||
* Keep the signal lines to the card as short as possible.
|
||||
* Do not use diodes to derive the card's supply voltage. Use a 3.3V voltage regulator instead.
|
||||
* Have a stable, buffered power supply and use capacitors for correct voltage regulator
|
||||
operation (see the schematics linked above).
|
||||
* Use extra capacitors of 50uF and 100nF as close to the card as possible.
|
||||
* When using an integrated level shifter or no level shifting at all (see the next question),
|
||||
try adding a pullup of 50k from the data-out line of the card to 3.3V.
|
||||
* Make sure the limiting frequency of the level shifter is not exceeded. Have a look into its
|
||||
datasheet!
|
||||
* Check the signals with a scope.
|
||||
|
||||
Q: What alternatives to resistor level shifting exist?
|
||||
A: If you want to use additional devices with SPI or the resistor solution appears too ugly, there
|
||||
are two possibilities. Either operate the whole circuit with a single 3.3V supply and no level
|
||||
shifting at all or use a level shifting IC which interfaces the memory card to the AVR.
|
||||
Depending on your requirements, adequate devices could include MAX3378E, MAX3392E, MAX3395E,
|
||||
74LVC245 and 74HCT4050 (optionally together with 74HCT125). Please check the datasheets for the
|
||||
required DC/AC characteristics!
|
||||
|
||||
Software
|
||||
--------
|
||||
|
||||
Q: What's the software license?
|
||||
A: GPLv2 or (for most parts) LGPLv2.1. Before using a file, read its license terms included at the
|
||||
beginning of the file.
|
||||
|
||||
Q: What's the programming language used?
|
||||
A: It's C, in compliance with the ISO C99 standard.
|
||||
|
||||
Q: What are these .patch-files provided?
|
||||
A: Those record the source code differences between the old and new release. If you edited your
|
||||
private sd-reader version, it might be easier to apply the patch files using the "patch" utility
|
||||
common on Unix-like systems, rather than manually inserting the changes by hand. For Windows
|
||||
users, the GnuWin32 project provides a port of "patch".
|
||||
|
||||
Q: Where can I learn more about the library interface and how to use it?
|
||||
A: Look into the HTML documentation provided online or within each source distribution. Also take
|
||||
the provided main.c as an example application and as a starting point.
|
||||
|
||||
Q: How do I adapt it to an ATmegaXYZ and my circuit in particular?
|
||||
A: Add your MCU-specific pin configuration to sd_raw_config.h. Some commonly used ones are already
|
||||
included.
|
||||
|
||||
Q: How do I adapt it to a different MCU clock?
|
||||
A: Change the MCU_FREQ variable within the Makefile.
|
||||
|
||||
Q: How do I adapt it to some different MCU architecture?
|
||||
A: Change sd_raw_init(), sd_raw_send_byte(), sd_raw_rec_byte() within sd_raw.c and the pin
|
||||
definitions within sd_raw_config.h appropriately.
|
||||
|
||||
Q: Can the library be used with Arduino?
|
||||
A: Yes. I do not have any experience with Arduino myself, but people report that it works with some
|
||||
minor modifications to the library code needed due to some different compiler settings. Please
|
||||
search the web for details.
|
||||
|
||||
Q: Can I use software SPI?
|
||||
A: Yes, but the code is not prepared for it.
|
||||
|
||||
Q: My application crashes somewhere in the lib. Is there some bug hidden?
|
||||
A: There might be a bug. Much more likely, however, is that you experience memory problems,
|
||||
especially heap/stack collisions. The crashes can appear everywhere, but typically this is not
|
||||
the place where the real problem is. Try to minimize the size of structures and other memory
|
||||
blocks your application uses. Sum up the amount of memory your application allocates with global
|
||||
and local variables and the memory you allocate dynamically with malloc(). The avr-nm utility
|
||||
also helps a lot here. When called with the "--print-size --size-sort" parameters, it lists all
|
||||
symbols and their code/memory size within the given file. See the avr-libc FAQ and the nm manual
|
||||
for further information.
|
||||
http://www.nongnu.org/avr-libc/user-manual/FAQ.html#faq_ramoverlap
|
||||
http://sourceware.org/binutils/docs/binutils/nm.html
|
||||
|
||||
Q: Opening the FAT filesystem fails. What can I do?
|
||||
A: Make sure there is a FAT16 or FAT32 filesystem on the card. This usually isn't possible for old
|
||||
cards with 16 MB or less. For larger ones, format the cards using the OS utilities, like the
|
||||
Windows Explorer, the Unix/Linux mkdosfs command or special SD card format tools.
|
||||

|
||||
http://www.sdcard.org/consumers/formatter/
|
||||
|
||||
Q: Writing to the card returns no failure, but when checking the file's content the data is not
|
||||
there. What happens?
|
||||
A: For performance reasons, writing to the card is always buffered. Before pulling the card out of
|
||||
its socket (or issuing a reset of the MCU), make sure sd_raw_sync() gets called such that all
|
||||
buffered data is written out to permanent card storage.

The generation of the short 8.3 file name is quite simple. The first eight characters are used for the filename. The extension, if any, is made up of the first three characters following the last dot within the long filename. If the filename (without the extension) is longer than eight characters, the lower byte of the cluster number replaces the last two characters to avoid name clashes. In any other case, it is your responsibility to avoid name clashes.</dd></dl>

The generation of the short 8.3 file name is quite simple. The first eight characters are used for the filename. The extension, if any, is made up of the first three characters following the last dot within the long filename. If the filename (without the extension) is longer than eight characters, the lower byte of the cluster number replaces the last two characters to avoid name clashes. In any other case, it is your responsibility to avoid name clashes.</dd></dl>

<div class="textblock"><p>This project provides a general purpose library which implements read and write support for MMC, SD and SDHC memory cards. It includes</p>

|
||||
<li>low-level <a class="el" href="group__sd__raw.html">MMC, SD and SDHC read/write routines </a></li>

<h2><a class="anchor" id="circuit"></a>
|
||||
The circuit</h2>
|
||||
<p>The circuit which was mainly used during development consists of an Atmel AVR microcontroller with some passive components. It is quite simple and provides an easy test environment. The circuit which can be downloaded on the <a href="http://www.roland-riegel.de/sd-reader/">project homepage</a> has been improved with regard to operation stability.</p>
|
||||
<p>I used different microcontrollers during development, the ATmega8 with 8kBytes of flash, and its pin-compatible alternative, the ATmega168 with 16kBytes flash. The first one is the one I started with, but when I implemented FAT16 write support, I ran out of flash space and switched to the ATmega168. For FAT32, an ATmega328 is required.</p>
|
||||
<p>The circuit board is a self-made and self-soldered board consisting of a single copper layer and standard DIL components, except of the MMC/SD card connector.</p>
|
||||
<p>The connector is soldered to the bottom side of the board. It has a simple eject button which, when a card is inserted, needs some space beyond the connector itself. As an additional feature the connector has two electrical switches to detect wether a card is inserted and wether this card is write-protected.</p>

<h2><a class="anchor" id="software"></a>
|
||||
The software</h2>
|
||||
<p>The software is written in C (ISO C99). It might not be the smallest or the fastest one, but I think it is quite flexible. See the project's <a href="http://www.roland-riegel.de/sd-reader/benchmarks/">benchmark page</a> to get an idea of the possible data rates.</p>
|
||||
<p>I implemented an example application providing a simple command prompt which is accessible via the UART at 9600 Baud. With commands similiar to the Unix shell you can browse different directories, read and write files, create new ones and delete them again. Not all commands are available in all software configurations.</p>
|
||||
<ul>
|
||||
<li><code>cat <file></code><br/>
|
||||
Writes a hexdump of <file> to the terminal.</li>
|
||||
<li><code>cd <directory></code><br/>
|
||||
Changes current working directory to <directory>.</li>
|
||||
<li><code>disk</code><br/>
|
||||
Shows card manufacturer, status, filesystem capacity and free storage space.</li>
|
||||
<li><code>init</code><br/>
|
||||
Reinitializes and reopens the memory card.</li>
|
||||
<li><code>ls</code><br/>
|
||||
Shows the content of the current directory.</li>
|
||||
<li><code>mkdir <directory></code><br/>
|
||||
Creates a directory called <directory>.</li>
|
||||
<li><code>mv <file> <file_new></code><br/>
|
||||
Renames <file> to <file_new>.</li>
|
||||
<li><code>rm <file></code><br/>
|
||||
Deletes <file>.</li>
|
||||
<li><code>sync</code><br/>
|
||||
Ensures all buffered data is written to the card.</li>
|
||||
<li><code>touch <file></code><br/>
|
||||
Creates <file>.</li>
|
||||
<li><code>write <file> <offset></code><br/>
|
||||
Writes text to <file>, starting from <offset>. The text is read from the UART, line by line. Finish with an empty line.</li>
|
||||
</ul>

The static RAM is mostly used for buffering memory card access, which
|
||||
improves performance and reduces implementation complexity.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
Please note that the numbers above do not include the C library functions
|
||||
used, e.g. some string functions. These will raise the numbers somewhat
|
||||
if they are not already used in other program parts.
|
||||
</p>
|
||||
|
||||
<p>
|
||||
When opening a partition, filesystem, file or directory, a little amount
|
||||
of RAM is used, as listed in the following table. Depending on the library
|
||||
configuration, the memory is either allocated statically or dynamically.

|
||||
Adapting the software to your needs</h2>
|
||||
<p>The only hardware dependent part is the communication layer talking to the memory card. The other parts like partition table and FAT support are completely independent, you could use them even for managing Compact Flash cards or standard ATAPI hard disks.</p>
|
||||
<p>By changing the MCU* variables in the Makefile, you can use other Atmel microcontrollers or different clock speeds. You might also want to change the configuration defines in the files <a class="el" href="fat__config_8h.html" title="FAT configuration (license: GPLv2 or LGPLv2.1)">fat_config.h</a>, <a class="el" href="partition__config_8h.html" title="Partition configuration (license: GPLv2 or LGPLv2.1)">partition_config.h</a>, <a class="el" href="sd__raw__config_8h.html" title="MMC/SD support configuration (license: GPLv2 or LGPLv2.1)">sd_raw_config.h</a> and <a class="el" href="sd-reader__config_8h.html" title="Common sd-reader configuration used by all modules (license: GPLv2 or LGPLv2.1)">sd-reader_config.h</a>. For example, you could disable write support completely if you only need read support.</p>
|
||||

<h2><a class="anchor" id="bugs"></a>
|

Bugs or comments?</h2>
|
||||
<p>If you have comments or found a bug in the software - there might be some of them - you may contact me per mail at <a href="mailto:feedback@roland-riegel.de">feedback@roland-riegel.de</a>.</p>

Acknowledgements</h2>
|

<p>Thanks go to Ulrich Radig, who explained on his homepage how to interface MMC cards to the Atmel microcontroller (<a href="http://www.ulrichradig.de/">http://www.ulrichradig.de/</a>). I adapted his work for my circuit.</p>

/**
|
||||
* \mainpage MMC/SD/SDHC card library
|
||||
*
|
||||
* This project provides a general purpose library which implements read and write
|
||||
* support for MMC, SD and SDHC memory cards.
|
||||
*
|
||||
* It includes
|
||||
* - low-level \link sd_raw MMC, SD and SDHC read/write routines \endlink
|
||||
* - \link partition partition table support \endlink
|
||||
* - a simple \link fat FAT16/FAT32 read/write implementation \endlink
|
||||
*
|
||||
* \section circuit The circuit
|
||||
* The circuit which was mainly used during development consists of an Atmel AVR
|
||||
* microcontroller with some passive components. It is quite simple and provides
|
||||
* an easy test environment. The circuit which can be downloaded on the
|
||||
* <a href="http://www.roland-riegel.de/sd-reader/">project homepage</a> has been
|
||||
* improved with regard to operation stability.
|
||||
*
|
||||
* I used different microcontrollers during development, the ATmega8 with 8kBytes
|
||||
* of flash, and its pin-compatible alternative, the ATmega168 with 16kBytes flash.
|
||||
* The first one is the one I started with, but when I implemented FAT16 write
|
||||
* support, I ran out of flash space and switched to the ATmega168. For FAT32, an
|
||||
* ATmega328 is required.
|
||||
*
|
||||
* The circuit board is a self-made and self-soldered board consisting of a single
|
||||
* copper layer and standard DIL components, except of the MMC/SD card connector.
|
||||
*
|
||||
* The connector is soldered to the bottom side of the board. It has a simple
|
||||
* eject button which, when a card is inserted, needs some space beyond the connector
|
||||
* itself. As an additional feature the connector has two electrical switches
|
||||
* to detect wether a card is inserted and wether this card is write-protected.

||||
*
|
||||
* \section software The software
|
||||
* The software is written in C (ISO C99). It might not be the smallest or
|
||||
* the fastest one, but I think it is quite flexible. See the project's
|
||||
* <a href="http://www.roland-riegel.de/sd-reader/benchmarks/">benchmark page</a> to get an
|
||||
* idea of the possible data rates.
|
||||
*
|
||||
* I implemented an example application providing a simple command prompt which is accessible
|
||||
* via the UART at 9600 Baud. With commands similiar to the Unix shell you can browse different
|
||||
* directories, read and write files, create new ones and delete them again. Not all commands are
|
||||
* available in all software configurations.
|
||||
* - <tt>cat \<file\></tt>\n
|
||||
* Writes a hexdump of \<file\> to the terminal.
|
||||
* - <tt>cd \<directory\></tt>\n
|
||||
* Changes current working directory to \<directory\>.
|
||||
* - <tt>disk</tt>\n
|
||||
* Shows card manufacturer, status, filesystem capacity and free storage space.
|
||||
* - <tt>init</tt>\n
|
||||
* Reinitializes and reopens the memory card.
|
||||
* - <tt>ls</tt>\n
|
||||
* Shows the content of the current directory.
|
||||
* - <tt>mkdir \<directory\></tt>\n
|
||||
* Creates a directory called \<directory\>.
|
||||
* - <tt>mv \<file\> \<file_new\></tt>\n
|
||||
* Renames \<file\> to \<file_new\>.
|
||||
* - <tt>rm \<file\></tt>\n
|
||||
* Deletes \<file\>.
|
||||
* - <tt>sync</tt>\n
|
||||
* Ensures all buffered data is written to the card.
|
||||
* - <tt>touch \<file\></tt>\n
|
||||
* Creates \<file\>.
|
||||
* - <tt>write \<file\> \<offset\></tt>\n
|
||||
* Writes text to \<file\>, starting from \<offset\>. The text is read
|
||||
* from the UART, line by line. Finish with an empty line.
|
||||

|
||||
* <p>
|
||||
* The following table shows some typical code sizes in bytes, using the 20090330 release with a
|
||||
* buffered read-write MMC/SD configuration, FAT16 and static memory allocation:

|
||||
*
|
||||
* <p>
|
||||
* The static RAM is mostly used for buffering memory card access, which
|
||||
* improves performance and reduces implementation complexity.
|

|

|

* Please note that the numbers above do not include the C library functions
|

|
||||
* if they are not already used in other program parts.
|

|
||||
*
|
||||
* <p>
|
||||
* When opening a partition, filesystem, file or directory, a little amount
|
||||
* of RAM is used, as listed in the following table. Depending on the library
|
||||
* configuration, the memory is either allocated statically or dynamically.

*
|
||||
* \section adaptation Adapting the software to your needs
|
||||
* The only hardware dependent part is the communication layer talking to the
|
||||
* memory card. The other parts like partition table and FAT support are
|
||||
* completely independent, you could use them even for managing Compact Flash
|
||||
* cards or standard ATAPI hard disks.
|
||||
*
|
||||
* By changing the MCU* variables in the Makefile, you can use other Atmel
|
||||
* microcontrollers or different clock speeds. You might also want to change
|
||||
* the configuration defines in the files fat_config.h, partition_config.h,
|
||||
* sd_raw_config.h and sd-reader_config.h. For example, you could disable
|
||||
* write support completely if you only need read support.
|
||||
*
|
||||
* For further information, visit the project's
|
||||
* <a href="http://www.roland-riegel.de/sd-reader/faq/">FAQ page</a>.
|
||||
*
|
||||
* \section bugs Bugs or comments?
|
||||
* If you have comments or found a bug in the software - there might be some
|
||||
* of them - you may contact me per mail at feedback@roland-riegel.de.
|
||||
*
|
||||
* \section acknowledgements Acknowledgements
|
||||
* Thanks go to Ulrich Radig, who explained on his homepage how to interface
|
||||
* MMC cards to the Atmel microcontroller (http://www.ulrichradig.de/).
|
||||
* I adapted his work for my circuit.
