A common question, how to enable memory card on phone, interests many owners of mobile devices, on which there is very little free space for storing useful information. Sometimes users even have a need to copy the necessary files into it and free up the memory of their mobile phone.
Installing a memory card on the phone
1. In order to install a memory card on the device, you will need to find a connection slot for this part on the phone itself. As a rule, it is located on the side of the gadget panel.
2. Then the selected map is loaded here, which is suitable for the user in terms of volume.
3. It is necessary to check how firmly the part is fixed in the slot. If all is well, an expressive click will be heard. As a rule, nothing else needs to be done to detect the memory card by the telephone. However, there may be exceptions.
What to do if the memory card is not visible to the phone
Often, reading information from a working memory card, as opposed to an elementary one, becomes a real problem. That is why many users are wondering how to turn on the memory card on the phone, if it is not visible as a USB device and is not displayed at all on the device.
1. If such an add-on is installed on the mobile phone, then the difficulties can be solved by using a card reader. This device is a true universal adapter. His work is focused just on reading information from various memory cards.
2. Card readers are different: multi-format, built-in and single format. That is why, when choosing it, you should pay attention to the use of the memory card itself in the phone: Micro SD, Mini SD or SD.
3. To turn on the memory card, you first need to connect the card reader to the PC. On the phone, you must close all applications and folders.
Then the memory card is removed from the mobile phone and loaded into a special device. After the adapter is connected, the information will be displayed in a folder named "my computer". As a rule, after data manipulation, the card begins to interact perfectly with the phone itself. However, for safety reasons, it is still recommended to transfer data from a mobile device to a PC.
Among other tips, it is worth noting that many experts recommend purchasing the largest memory card in terms of volume.

Installation of programs on the internal memory of the tablet is carried out by default. To put the application on the built-in memory card, you just need to perform the standard installation. It will take a little longer to send it to external media. One simple setup session will clean up the device's file system, installing each new application to the SD card.
Option 1: specifying the installation address
During installation, some programs ask the user where they will be accommodated. It is not difficult to indicate the address of the installation. Choose a removable memory card, and you're done. But this applies only to some applications, such a minority.
Option 2: set the installation path in advance
The application must support the app2sd patch if the Android OS version on the tablet is earlier than 2.2. There will be no such items in the settings. For all new versions, such an algorithm for solving the problem is suitable.
Go to "Settings", find the item "Memory". Click on it and the memory settings menu will open. Here you can also find out about the amount of free memory on your device, how much space on the tablet in general, how much internal memory is occupied. Some people insert an SD card into a card reader, and find out the data about the flash drive on the computer, not knowing that it can be done on the tablet.
Find the "Default Burn Disc" section, which offers several sources for installing applications. Choose "SD card" from among them. Click on this item, and you will see a circle opposite it. Now the installation of applications to the memory card on the tablet occurs by default.
Option 3: Using third-party programs
Most likely this method will help you. But he demands. You can find out whether or not there is a root right on the tablet by. We download special applications, like FolderMount or GL to SD, which will help you transfer game and program data to an SD memory card. See video instructions below:
Option 3
Install a program on your tablet PC that will provide an option to select the installation address. Before the direct installation of the application, a dialog box will appear in which you specify the installation address.
This is the most convenient option among those offered. Because a forced installation "by default" is not desirable in all cases. Utilities such as InstallManager, MagicUneracer will help organize an economical and efficient filling of the tablet's memory. By the way, these same programs also perform uninstallation of programs with all auxiliary files.
If the app is not installed on an SD card
Open the "Applications" item in "Settings". In the list of applications, select the one that you would like to transfer to the removable card. Click on the app icon and a menu will open. See if it has a "Transfer" option. If so, click on the option button and select a memory card. This procedure does not require the installation of additional software, you can do it yourself.
Almost every Android device now supports memory cards (microSD). However, sometimes there are problems associated with its detection in the device. There may be several reasons for the occurrence of such a problem, and certain manipulations are required to solve them. Next, we will look at methods of correcting such an error.
Before proceeding with the instructions below, we recommend that you do the following:
- Reboot your device. Perhaps the problem that has arisen is an isolated case, and the next time you start the device, it will simply disappear and the flash drive will work correctly.
- Reconnect. Sometimes the removable storage medium is not displayed because the contacts are loose or clogged. Pull it out and insert it back, then check if the detection is correct.
- Maximum volume. Some mobile devices, especially old ones, support memory cards only of certain sizes. We advise you to familiarize yourself with this characteristic on the official website of the manufacturer or in the instructions in order to make sure that an SD card with that much memory functions normally with your device.
- Check on other devices. It may well be that the flash drive is damaged or broken. Insert it into another smartphone or tablet, laptop or computer to make sure it works. If it is not readable on any equipment, you should replace it with a new one.
In addition to such detection problems, an error occurs notifying that the flash drive has been damaged. For a detailed guide on how to fix it, read our material at the link below.
If the previous tips have not yielded any results and the storage medium is still not detected by your smartphone or tablet, pay attention to the steps below. We've arranged them in order of difficulty so that you can implement each one in order without much effort.
Method 1: Delete cache data
The device collects temporary data every day. They not only take up physical space in memory, but can also cause various malfunctions in the operation of the device. First of all, we recommend erasing the cache through the menu Recovery... In it you should select the item "Wipe Cache Partition", wait for the procedure to complete and restart the phone.
Detailed instructions on how to switch to Recovery mode in the Android operating system and how else you can delete the cache can be found in the following articles.
Method 2: Check for memory card errors
As part of this method, follow a series of simple steps:
If scanning for errors did not help, then you need to take more drastic measures.
Method 3: Formatting the media
To complete this method, you will also need to connect your SD card to your computer or laptop using adapters or special adapters.
Please note that this procedure will erase all information from the removable media, therefore, before starting, we advise you to save important data in any other convenient place.
If you have any difficulties with formatting, we recommend that you read our other article at the link below. There you will find seven ways to solve this problem, and you can easily fix it.
Most often, deleting data from a card helps in cases where it has ceased to be detected after connecting to other equipment. You just need to follow the instructions above, then immediately insert the media into your smartphone or tablet and check its performance.
Method 4: create a clean volume
Sometimes, due to the fact that the card has a hidden section, its memory is not enough to save information from a smartphone. Among other things, this creates detection problems. To eliminate them, you need to connect the card to a PC and follow these steps:
- Through the menu "Start" go to "Control Panel".
- Select a category here "Administration".
- Among the list of all components, find and double-click on "Computer Management".
- In the window that opens, you should select "Disk Management".
- Here, check the number of the disk that is your flash drive, and also pay attention to the total amount of memory. Write down or remember this information as it will come in handy later.
- Key combination Win + R run the snap "Run"... Enter cmd in the line and click on "OK".
- In the window that opens, enter the command diskpart and click Enter.
- Grant permission to run the utility.
- You are now on to the disk partitioning program. She has identical Command line view. Here you need to enter list disk and click on again Enter.
- Check out the list of disks, find your USB flash drive there, then enter select disk 1, where 1 - the disc number of the required medium.
- All that remains is to clear all data and partitions. This procedure is performed using the clean command.
- Wait for the process to complete and you can close the window.
Now we have achieved that the SD-card is completely clean: all information, open and hidden sections have been removed from it. A new volume must be created in the phone for normal operation. This is done like this:
- Repeat the first four steps from the previous instructions to return to the Disk Management menu again.
- Select the required removable media, right-click on the mark with its memory and select "Create new volume".
- This will open the Simple Volume Creation Wizard. To start working with it, click on "Further".
- You do not need to specify the size of the volume, let it take up all the free space, so the flash drive will work better with a mobile device. So just go to the next step.
- Assign any free letter to the volume and press "Further".
- Formatting should be done if the default format is not FAT32... Then select this file system, leave the cluster size "Default" and move on.
- Upon completion of the procedure, you will be presented with information about the selected parameters. Check them out and quit.
- Now on the menu "Disk Management" you see a new volume that takes up all of the logical space on the memory card. This means that the process was completed successfully.
All that remains is to remove the USB flash drive from your PC or laptop and insert it into your mobile device.
We displayed a picture on the display from an sd card, but some points were missed in it, the first was the connection of the card itself, the second was only a part of the library's functions was considered Petit FatFs, let's dwell on these points in more detail.
Communication with the card is possible through one of two interfaces, SPI or SD.
I must say that the SD interface can work in one-bit and four-bit modes.
The SPI card connection diagram is standard and looks like this, the unused card pins need to be pulled up to the power supply using a 10K resistor.
But in amateur designs, pull-up resistors are often neglected, simplifying the wiring diagram.
It should be noted that when connected via SPI, the card is very demanding on the supply voltage and a small drop in the supply voltage leads to the inoperability of the card, this has been verified by personal experience, there is nothing to say about the SD interface, I have not tried it yet. I wrote all this to the fact that on the power supply, it is imperative to install capacitors... As for the choke, it must be rated for a current of up to 100mA, but it is not necessary to install it.
In the diagrams shown above, it can be seen that the card needs 3.3 volts for operation, respectively, the voltage in the data transmission lines should not go beyond the range of 0 - 3.3 volts, and then the question arises, what to do if the MK is powered by 5 volts?
The answer is simple, you need to match the data transmission lines, and this can be done using a conventional resistive divider.
The diagram shows that the MISO line does not need to be coordinated the way data is transmitted along this line. from card to MK.
In fact, few people connect the card directly to the MK, it is much more convenient to connect the connector for the card to the MK or buy a shield with a connector and all the necessary strapping.
With the connection figured out, let's now look at how to use the library Petit FatFs which is designed for 8-bit microcontrollers with small memory size.
The library consists of 5 files:
integer.h- a header file that describes the main data types.
diskio.h- a header file in which prototypes of low-level functions for working with a disk and the status codes that they return are declared.
diskio.c- low-level functions must be implemented in this file, initially there are "stubs" there.
pffсonf.h- configuration file.
pff.h- a header file in which prototypes of functions for interacting with the disk file system are declared.
pff.c- the file contains implementations of functions for interacting with the disk file system.
It can be seen that in order for the library to work, it is necessary to implement low-level functions. But if we are talking about AVR or PIC, for them the site can download an example of working with the library, in which there is a file mmc, it already implements low-level functions. It is also necessary to set the library configuration in the pff.h file and write the functions necessary for the SPI to work.
Petit FatFs functions.
FRESULT pf_mount (FATFS *)- the function mounts / unmounts the disk. This function must be called before starting to work with the disk, if you call the function with a null pointer, the disk is unmounted. The function can be called at any time.
Parameters
FATFS * fs- a pointer to an object of FATFS type, a description of this structure can be found in the pff.h file. We just need to declare a variable of this type.
Return values:
FR_OK (0)
FR_NOT_READY- the device cannot be initialized
FR_DISK_ERR- an error occurred while reading from the disk
FR_NO_FILESYSTEM- the disk does not have the correct FAT partition
FATFS fs; // declare an object of FATFS type // mount the disk if (pf_mount (& fs) == FR_OK) (// the disk is mounted, we work with it // unmount the disk pf_mount (NULL);) else (// failed to mount the disk )
FRESULT pf_open (const char * path)- the function opens an existing file. After the file is open, you can work with it, that is, read from it and write to it. You can work with an open file until another file is opened. The function can be called at any time.
Parameters
const char * path- pointer to a string indicating the path to the file. The path must be specified completely relative to the root directory, separating directories with a slash.
Return values:
FR_OK (0)- is returned if the function is completed successfully
FR_NO_FILE- File not found
FR_DISK_ERR- disk error
FR_NOT_ENABLED- the disk was not mounted
FATFS fs; // declare an object of FATFS type // mount the disk if (pf_mount (& fs) == FR_OK) (// open the file in the root directory if (pf_open ("hello.txt") == FR_OK) (// do something) // open the file in the new folder if (pf_open ("new / hello.txt") == FR_OK) (// do something) // dismantle the disk pf_mount (NULL);) else (// failed to mount disk)
FRESULT pf_read (void * buff, WORD btr, WORD * br)- the function reads the specified number of bytes from the file and saves them to the buffer. If the number of bytes read is less than specified, then the end of file has been reached.
#define _USE_READ 1
Parameters:
void * buff- pointer to the buffer in which the read data is stored
WORD btr- the number of bytes to read
WORD * br- a pointer to a variable that stores the number of bytes read.
Return values:
FR_OK (0)- is returned if the function is completed successfully
FR_DISK_ERR- disk error
FR_NOT_OPENED- the file was not opened
FR_NOT_ENABLED- the disk was not mounted
FATFS fs; // declare an object of type FATFS BYTE buff; // buffer for reading the file WORD br; // counter of bytes read // mount the disk if (pf_mount (& fs) == FR_OK) (// open the file in the root directory if (pf_open ("hello.txt") == FR_OK) (// read 10 bytes from it pf_read (buff, 10, & br); if (br! = 10) (// if br is not equal to 10 // then we have reached the end of the file)))
FRESULT pf_write (const void * buff, WORD btw, WORD * bw)- the function allows you to write data to an open file. In order for the function to work in the pffconf.h file, write
#define _USE_WRITE 1
Parameters:
void * buff- a pointer to the buffer that we want to write, a zero value finalizes the write
WORD btw- the number of bytes that we want to write
WORD * bw- a pointer to a variable storing the number of bytes that could be written. By analyzing this variable, you can find out whether the end of the file has been reached.
Return values:
FR_OK (0)- is returned if the function is completed successfully
FR_DISK_ERR- disk error
FR_NOT_OPENED- the file was not opened
FR_NOT_ENABLED- the disk was not mounted
Due to the fact that the library is designed for microcontrollers with a small memory size, this function has a number of limitations:
- you cannot create new files, and you can write only to existing ones
- file size cannot be increased
- the timestamp cannot be updated
- write operation can be started / stopped only at the sector boundary
- a read-only file attribute cannot deny writing
In order to understand the penultimate point, you need to know that the memory of the card is divided into blocks (sectors) of 512 bytes and recording can only be started from the beginning of a sector... Thus, if we want to write 1000 bytes, then the first sector will be written completely, and only 488 bytes will be written to the second, and the remaining 24 bytes will be filled with zeros.
To write to an open file, do the following:
- set the pointer to the sector border, if set not to the border, then the pointer will be rounded to the lower sector border
- call the write function the required number of times
- finalize the entry by calling a function with a null pointer
In order to give an example of how the recording function works, one more function needs to be considered.
FRESULT pf_lseek (DWORD offset)- sets a read / write pointer in an open file. You can set the pointer as an absolute or relative offset; for an absolute offset, you need to pass a number to the function
pf_lseek (5000);
for relative, pass the value of the pointer to the current position fs.fptr and the displacement value
pf_lseek (fs.fptr + 3000);
In order for the function to work in the pffconf.h file, write
#define _USE_LSEEK 1
Parameters:
DWORD offset- the number of bytes by which the pointer should be shifted.
Return values:
FR_OK (0)- is returned if the function is completed successfully
FR_DISK_ERR- disk error
FR_NOT_OPENED- the file was not opened
You can write data to a file as follows.
FATFS fs; // declare an object of type FATFS BYTE buff; // buffer for reading the file WORD br; // counter of bytes read // mount the disk if (pf_mount (& fs) == FR_OK) (// open the file in the root directory if (pf_open ("hello.txt") == FR_OK) (// set the pointer to the first sector pf_lseek (0); // write pf_write (buff, 10, & br); // finalize the write pf_write (0, 0, & br);))
I also leave here a piece of really working code that uses all the above functions.
#define F_CPU 8000000UL #define buff_size 10 #include
FRESULT pf_opendir (DIR * dp, const char * path)- the function opens an existing directory and creates a pointer to an object of the DIR type, which will be used to get a list of files in the open directory.
In order for the function to work in the pffconf.h file, write
#define _USE_DIR 1
Parameters:
DIR * dp- a pointer to a variable of the DIR type.
const char * path- pointer to a string that contains the path to the directory, directories are separated by a slash
Return values:
FR_OK (0)- is returned if the function is completed successfully
FR_NO_PATH- could not find a path
FR_NOT_READY- failed to initialize disk
FR_DISK_ERR- disk error
FR_NOT_ENABLED- the disk was not mounted
// declare FATFS variables fs; DIR dir; // mount the disk pf_mount (& fs); // open the directory pf_opendir (& dir, "MY_FOLDER");
FRESULT pf_readdir (DIR * dp, FILINFO * fno)- the function allows you to read the contents of a directory. To do this, open the directory with the pf_opendir () function and call pf_readdir (). Each time it is called, the function will return the name of the object (folder / file) located in the specified directory. When it loops through all the objects, it returns the null string in the fno.fname array element.
In order for the function to work in the pffconf.h file, write
#define _USE_DIR 1
Parameters:
DIR * dp- a pointer to a variable of the DIR type, which must be previously declared
FILINFO * fno- a pointer to a variable of the FILINFO type, which must be previously declared.
Return values:
FR_OK- successful completion of the function
FR_DISK_ERR- disk error
FR_NOT_OPENED- directory is not open
FATFS fs; FRESULT res; FILINFO fno; DIR dir; // mount the disk pf_mount (& fs); // open the directory res = pf_opendir (& dir, MY_FOLDER); // read the contents of the directory for (;;) (res = pf_readdir (& dir, & fno); // check if there were any errors while reading // and if there are more files in the specified directory if ((res! = FR_OK) || ( fno.fname == 0)) (break;) // display in a convenient way fno.fname usart_sendStr (fno.name); usart_sendStr (/ r);)
Well, in the end, I'll leave a working draft here.
