Great video, thank you so much for your help! As other users have mentioned, if using an stm32f0 discovery board, make sure to set the spi data size to 8 bits. I also ran into a error where I could not build my project with a max sector size of 4096 (too large) so I changed it to 2048 and it worked fine.
Awesome tutorial. I can confirm that this works on clone chip CS32F103 Bluepill board using 32Gig Transcend SD card . Thank you Controllers Tech for your hard work.
Thank you very much for your initiative. The only sensible code that I found after a long time of searching. But in the beginning there was a problem: the program did not always work.

Thank you so much for posting this video! I was able to get it working with an SD card formatted with a block size (allocation unit size) of 512 bytes. How do you get it to work with other block sizes (for example, I'm trying to use a block size of 4096 bytes)? Is that possible?

Try writing this DSTATUS my_status = SD_disk_initialize(0); if(my_status == STA_NOINIT ){ send_uart ("error in initializing SD CARD... "); } if (my_status == STA_NODISK){ send_uart ("No medium in the drive... "); } if (my_status == STA_PROTECT){ send_uart (" Write protected...

You are getting error in mount itself. There isn't much i can do here.. It Could be anything.. Check your connection Sd card is in FAT format ? Check the SPI speed, it should be around 2Mb/s Check the connection again.. there could be a loose wire.
Thank for going to the effort of publishing this. I’ve been wanting to get this working for a while so this video is going to be really useful. So far I’ve only “skim” watched it, and I’ve also looked at your website, but in both cases and for the life of me I can’t see where your fatfs_sd.c and fatfs_sd.h files are coming from. i.e. you say copy them into the project, buy where are you copying them from ? Apologies if it’s obvious, and thanks again.

Hello! Thanks for the video, it seemed to me quite clear and concise! I have a problem however. After doing the f_open command I get a FR_NOT_READY from the fresult. I have followed all the indications in the video. The only thing that I don't understand is the clock. I have an STM32WB and as I am new to this I have no clue how to set it, so I basically just let it do it's thing. Do you have any idea why I might get that error?
@@ControllersTech Hey! I've just done it and there is no change. I get the same error. (I have a 16Gb card) I want to ask you though, why do you set for your clock the two options "HSE" and "PLLCLK" together? If I do this for my microcontroller I instantly get some 0xfffff8 error or something about "Failed to execute MI command". Also when you wrote this: fresult = f_mount(&fs, "/", 1); I saw that here you put 0 and on the website there's 1. What is this for? Thanks for answering!
HSE is for selecting external crystal for clock PLL is phase loop clock use in all the ARM processors. If u are having problems with the clock, i would advice you to not select the HSE and leave the clock input at HSI and use HCLK as 50 or 60 MHz. This video was made long ago, and i have modifies the code after that. That's why you might see some changes. Although the process remains same. Since it seems like you don't have much knowledge about stm32, i would say first try blinking led and start low.
Good morning i have a little project that i have to do but do you think that we can transfer files between two stm32 with spi ( files like .txt) thank youu
Ok I built this for STM32F411CEU WEACT board. using Chan's FatFs R0.12c Everthing works good except the "file.size" reference. This has been replaced in ChaN's FatFs R0.12c version with f_size(&fil).

I don't know. It could be anything... Are u initialising all the peripherals by your own or using cubemx ? Also check what error are you getting. You can do this by checking the error status.
I have stm32f103c8 and it does not support SDIO, so not possible there. But yes, i will soon publish a video about SDIO for those controllers, which supports it

I am using F401RE. I am finding problem in disk initialization. 1. Even when I am not inserting the card there is no difference. It is executing f_mount successfully. 2. The program does not enter the line ENTER_FF(fs) in ff.c for volume locking.
1. Yes that's the bug in the code. 2. I don't know much about it. I ported the code so that it can work with HAL library. What kind of error are u getting exactly
@@ControllersTech I am not able to fetch any values in fs FATFS pointer in ff.c. I am unable to understand why this is happening. I also tried to understand and fetch information about the libraries. But none understood to an extent to solve the problem. Also how did you port the code ? Probably that can work for me too.

I added fatfs_sd.c and .h to their folder (Src and Inc respectively), and clicked "Add Existing File to group Application/User". Is there anything else to do to properly link the drivers?
@@ControllersTech Would it be preferable for me to use SDIO, rather than SPI, as it seems my board features a 4bit bus SDIO interface, which I've heard is 4 times as fast as SPI?
"0" means the card can be mounted later also. We have executed the command and now it can mount anytime. "1" means mount the card immediately. "/" Is the path of the sd card, where the mount will take place.
hello , first of all thanks for this tutorial. I tried this project with stm32f446re and it works pretty well. But i need to save a value every 10us at specific .txt file.

Do you have recommended changes in the above code to enhance performance? Thank you !
Your software for me not worked. I make all the things and the total size shows zero and not write or read anything. I did all of the video and not work. I am using 2GB micro sd

In my project (STM32G017...) f_mount did not succeed but simply hang. Upon further debug inspection it hang/loop endlessly inside a HAL_DELAY() function (fatfs_sd.c --> void SELECT(void) --> HAL_Delay(1))...

Maybe this helps someone else too.
I did in Arduino and the SD CARD kit that i have work very well. I buy one like your video, but your software don´t write or read anything of SD CARD, not work. I tryed to format in PC but nothing happens, always the same bad things.
You posted the comment on the website right? Just because you can't get it to work, "you think the code is very wrong" ? Sort the comments to "newest first" and see how many people got it to work.
@@ControllersTech Yes, i did all the things and not write or read, but with arduino read and write. I format with fat and then i tryed with fat32, anyone works. Why in arduino works very well. I have blue pill stm32f103c8t6 and i have this board to put the card
@@ControllersTech I copy your program and nothing happens, i did a lot of times and nothing happen or 2G micro SD card, only with Arduino, this is my question. Maybe there is something very simple that i don´t know
I don't know why it isn't working for you. Try using external 5V supply to the module. Don't use the bluepill's 5V. Also some particular types of sd card don't work. I don't remember which one exactly, but read the comments as some people have pointed it out.
It seems f_write can not exceed 1023 for "btw" which is the number of bytes to write. If I try to write 1024 byte, I have FR_DISCK_ERR. Can you help me, if that is the maximum length I can write Or there is another problem to be solved. Thank you
the problem solved. I think it is a bug in the Fatfs_sd.c In function "SD_TxDataBlock" there is NO "return TRUE" if the token =0xFD, it will be always "return False" my solution is just adding "else" for the "If" statement and return TRUE there. Also, eclipse raise a warning there ('resp' may be used uninitialized in this function) which is make sense in case of 0xFD token.
Adding this driver to my project overflowed my RAM by like 11kB, any idea where all this extra memory allocation is coming from? I've skimmed through fastfs_sd.c and .h and can't see anything obvious.
Can't say really.. which controller are u using btw ? Try not using my code. See the video and write yourself. That way you always know what u r doing and the places, where things get messed up.

From where do i copy the library files fatfs_sd.c and .h files into the folders of project.
Just download the code. They are in the inc and sec folders
Great very good information, would you recommend some books from where you are learning all that, please I would appreciate it very much.
Don't know man.. I generally use the sensor datasheet itself. And rest is the research..
there's a book called Mastering STM32 - very useful.
i m using this method and one of my sd card is working fine but other is not working. But both sd cards are working fine in laptop. I dont know what is wrong.
Excellent tutorial.
thank you sir once again.
ERROR!!! in mounting SD CARD...
SD CARD Total Size: 0
SD CARD Free Space: 0
File1.txt is opened and it contains the data as shown below
File2.txt created and data is written
SD CARD UNMOUNTED successfully...
@controllerstech am using stm32l476rg micro controller when interfacing with micro sdcard adapter am using your program to control it as per your procedure to settings in cubemx....but i get the "ERROR!!! IN mounting sd card" what mistake maybe occurred in my side...please give the solution
You are getting error in mount itself. There isn't much i can do here.. It Could be anything..
Check your connection
Sd card is in FAT format ?
Check the SPI speed, it should be around 2Mb/s
Check the connection again.. there could be a loose wire.
@@ControllersTech my SD CARD is in FAT32(default) type.....how can i change into FAT type .....
@@ControllersTech when am debugging this code "fresult" return a FR_DISK_ERROR givs....what is the problem may happen...please give the solution....
Wait for few hrs. I am updating the code. It might work after that. Check after 4 hrs
Code updated... check the description
Thank for going to the effort of publishing this. I’ve been wanting to get this working for a while so this video is going to be really useful. So far I’ve only “skim” watched it, and I’ve also looked at your website, but in both cases and for the life of me I can’t see where your fatfs_sd.c and fatfs_sd.h files are coming from. i.e. you say copy them into the project, buy where are you copying them from ? Apologies if it’s obvious, and thanks again.
Download the code. Those files are present in src folder and inc folder
have you tried interfacing sht31 temperature and humidity sensor?
and cmcu-811 VOC sensor?
it would be very helpful if you post its tutorial
I don't have those modules.. will buy them when things will be better...
@@ControllersTech sure.... i am sharing my email adress let's have some conversation there.... may be i can help you buying those modules... or if u are from india i can send that module to ue place

Thanks, it's help me a lot!
hello sir, please make video on MFRC522 RFID with stm32 f4
Hello! Tell me, please, how can I assign a file name to some buffer?
Does not print the value in the variable.Printing ASCI value.Can I fixed?
How are u Passing the variable ?
Hello! Thanks for the video, it seemed to me quite clear and concise!
I have a problem however. After doing the f_open command I get a FR_NOT_READY from the fresult.
I have followed all the indications in the video. The only thing that I don't understand is the clock. I have an STM32WB and as I am new to this I have no clue how to set it, so I basically just let it do it's thing.
Do you have any idea why I might get that error?
Some connection problem. Make sure the card is formatted with FAT or FAT32
Also try to reduce the SPI speed and see if it can help
@@ControllersTech Hey! I've just done it and there is no change. I get the same error. (I have a 16Gb card)
I want to ask you though, why do you set for your clock the two options "HSE" and "PLLCLK" together? If I do this for my microcontroller I instantly get some 0xfffff8 error or something about "Failed to execute MI command".
Also when you wrote this: fresult = f_mount(&fs, "/", 1); I saw that here you put 0 and on the website there's 1. What is this for?
Thanks for answering!
HSE is for selecting external crystal for clock
PLL is phase loop clock use in all the ARM processors.
If u are having problems with the clock, i would advice you to not select the HSE and leave the clock input at HSI and use HCLK as 50 or 60 MHz.
This video was made long ago, and i have modifies the code after that. That's why you might see some changes.
Although the process remains same.
Since it seems like you don't have much knowledge about stm32, i would say first try blinking led and start low.
I face the same issue. Did you fix it?
I am trying to create the file but file is not able to get created
hello sir , i want to interface sd card in spi mode with adi sc 594 mcu , do u have any link for other mcu then stm32
Good morning i have a little project that i have to do but do you think that we can transfer files between two stm32 with spi ( files like .txt) thank youu
Ok I built this for STM32F411CEU WEACT board. using Chan's FatFs R0.12c
Everthing works good except the "file.size" reference.
This has been replaced in ChaN's FatFs R0.12c version with f_size(&fil).
help me, I don't find a fsize, where is it?
I have updated the code on 1st JULY 2020. Read the Description for more info.
where can i download fatfs_sd.c and fatfs_sd.h libary ?
@@emreseyyar5078 go to the link in the description.. download the code, and you can find the files where i put them in the video
Thank you for the tutorial! Successfully tested on L433 Nucleo board! :) (with some small adaptations of course)
I put external 5V and not worked. I changed of sd card to another one of 16GB and still not working
One more comment from you and i will block you.
I told you, ask in those groups. There is no point in spamming on RUclips
I am trying to access SD card using MikroC for the Board-STM32F446RE...I am facing a problem on Intializing the card ...The statement Fat32_init() does not seems to be working...
And there is no response from the MISO line .
Can you please help on this.
I don't know. It could be anything... Are u initialising all the peripherals by your own or using cubemx ?
Also check what error are you getting. You can do this by checking the error status.
The wiring sketch on the thumbnail is wrong.
Is there a way to read last 'x' number of bytes from the card?
Yeah.. You can take a look at the f_lseek.
Basically just move the pointer to (file size - x), and than read
I am getting this: ERROR!!! in mounting SD CARD...
----> I had formatted with FAT and FAT32, i used 2 micro SD cards and anyone works
Hey, I'm saving data on .csv format, and I can't update the file using f_lseek, cause I think it doesn't recognize the filinfo.fsize. Have any tips?
you can also get the size using the function f_size

Sir how to write sensor data to file.txt I am using buf but display zeros only f_sleek(&fil,fil.fsize) but error occur help me please
open it as to append data

and than write
f_write(&fil, data, strlen (data), &bw);
Are you Tried SDIO , sd CARD INTERFACE IN stm32f103rctxx Series?
I have stm32f103c8 and it does not support SDIO, so not possible there. But yes, i will soon publish a video about SDIO for those controllers, which supports it
How to make a file with increment filename?
Can i make it with same configuration like in your video?
File name is a string.
use something like this
sprintf(namebuf, "file%d",indx++);
That's it. Namebuf will have the file names like file1 file2 etc.
Thank you for the video. I'm facing problem in writing to the SD card. The file gets created but not able to write. The f_write returns FR_INT_ERR. Can you please let me know what could be the issue?
Note : I am able to read the data written on the card
that's same with me, how did you solve that?
I am using F401RE. I am finding problem in disk initialization.
1. Even when I am not inserting the card there is no difference. It is executing f_mount successfully.
2. The program does not enter the line ENTER_FF(fs) in ff.c for volume locking.
1. Yes that's the bug in the code.
2. I don't know much about it. I ported the code so that it can work with HAL library.
What kind of error are u getting exactly
@@ControllersTech I am not able to fetch any values in fs FATFS pointer in ff.c. I am unable to understand why this is happening. I also tried to understand and fetch information about the libraries. But none understood to an extent to solve the problem. Also how did you port the code ? Probably that can work for me too.
There are few things
* Some users have reported that SanDisk cards are not working.
* Make sure the sd card is formatted in FAT
* Use the smaller size at first. I have used a 1GB card while making this video
@@ControllersTech I am using F401RE nucleo board. Is it possible that there might be a hardware problem? I read at some places that that might be an issue.
Is there a way to send data with DMA ?
Hello thx for this tuto ! I would like to do the same but with ide arduino ... I didn't find help in the internet, do you think it's possible to interface sd card with stm32f103c8 using spi and arduino ide ?
Just use the arduino code. What's the issue ?
I am having problems with the "fatfs_sd.h" file : BYTE, DSTATUS, DRESULT, DWORD etc all all marked as "unkown type". Using Keil IDE 5
Also using the Nucleo-STM32F446RE, if that matters
I will take a look at it again...
Looks like you haven't generated the code properly or something to do with keil..
@@ControllersTech What do you mean by not generating the code properly? I am using CubeMX version 5.5 to generate Keil projects. I added fatfs_sd.c and .h to their folder (Src and Inc respectively), and clicked "Add Existing File to group Application/User". Is there anything else to do to properly link the drivers?
@@ControllersTech Would it be preferable for me to use SDIO, rather than SPI, as it seems my board features a 4bit bus SDIO interface, which I've heard is 4 times as fast as SPI?
what is the difference between "fresult = f_mount(&fs, "", 0);" and "fresult = f_mount(&fs, "/", 1);" ?
"0" means the card can be mounted later also. We have executed the command and now it can mount anytime.
"1" means mount the card immediately.
"/" Is the path of the sd card, where the mount will take place.
Thankyou sir..
@@ControllersTech I wanna ask again, why I can't use it inside HAL_TIM_PeriodElapsedCallback function for interrupt?
Valeu!
What write speed (MB/s) to card can I expect using this method?
Not much. Try around 2Mb/s and than go higher..
hello , first of all thanks for this tutorial. I tried this project with stm32f446re and it works pretty well. But i need to save a value every 10us at specific .txt file. For this reason i open , write and close the .txt file into an tim_irq_handler. It seems that the proccess of saving the data takes longer than expected. Do you have recommended changes in the above code to enhance performance?
Thank you !
thank you so much
The above link for the code etc just take you to a blank white page.
Can u please share this using standard peripheral library
Nope..
Your software for me not worked. I make all the things and the total size shows zero and not write or read anything. I did all of the video and not work. I am using 2GB micro sd
I have some strange problem during compiling. There are an compile error: "#error This file is not needed in current configuration. Remove from the project." in cc932.c.
Maybe things have changed with new version of HAL.. i have to check it again..
@@ControllersTech Thank you. Let me know, if you check, please. I have tried many solutions and I don't have an idea what to do.
Which controller do you have
@@ControllersTech I have checked F746ZG, but I have F410RRB and F103RB (all Nucleo boards) too. Of course I've changed header includes in every file with it.
Plzzzzzzzzzzzzz help me. I have an tf card module and want to use it with stm32f103c8t6 in arduino (using SPI). But I cant do it. Plzzzz help me.

Can we use sdhc cards with this project?
I open a text file, type something and close it, I want to open it again and add something else without losing what I wrote first. it is not working.why?
You have to use the append attribute..
Or do this
Open the file
Use lseek to point to the end of the file
Write the data
@@ControllersTech Thanks a lot
@@ControllersTech what is the the append attribute ?I dont know.Can you help me ?
FA_APPEND
In my project (STM32G017...) f_mount did not succeed but simply hang. Upon further debug inspection it hang/loop endlessly inside a HAL_DELAY() function (fatfs_sd.c --> void SELECT(void) --> HAL_Delay(1))... I followed the answer in this thread by overwriting the HAL_Delay function: community.st.com/s/question/0D50X00009XkXJp/hal-delay-stuck-in-infinite-loopnewbie I did not understand whats the cause of the problem but this answer worked for me. Maybe this helps someone else too.
I did in Arduino and the SD CARD kit that i have work very well. I buy one like your video, but your software don´t write or read anything of SD CARD, not work. I tryed to format in PC but nothing happens, always the same bad things.
You posted the comment on the website right?
Just because you can't get it to work, "you think the code is very wrong" ?
Sort the comments to "newest first" and see how many people got it to work.
@@ControllersTech Yes, i did all the things and not write or read, but with arduino read and write. I format with fat and then i tryed with fat32, anyone works. Why in arduino works very well. I have blue pill stm32f103c8t6 and i have this board to put the card
@@ControllersTech I copy your program and nothing happens, i did a lot of times and nothing happen or 2G micro SD card, only with Arduino, this is my question. Maybe there is something very simple that i don´t know
I don't know why it isn't working for you. Try using external 5V supply to the module. Don't use the bluepill's 5V.
Also some particular types of sd card don't work. I don't remember which one exactly, but read the comments as some people have pointed it out.
@@ControllersTech But why this sd cards works on arduino uno?
Thank you
Thanks sir how to write sensor reading data specially adc in txt file

It seems f_write can not exceed 1023 for "btw" which is the number of bytes to write. If I try to write 1024 byte, I have FR_DISCK_ERR.
Can you help me, if that is the maximum length I can write Or there is another problem to be solved.
Thank you
Try changing the data type of btw.. i don't remember what's defined in the code.. just increase it like from uint8 to uint16
@@ControllersTech "btw" is "UINT". I think it accepts 1024 byte
the problem solved. I think it is a bug in the Fatfs_sd.c
In function "SD_TxDataBlock" there is NO "return TRUE" if the token =0xFD, it will be always "return False"
my solution is just adding "else" for the "If" statement and return TRUE there.
Also, eclipse raise a warning there ('resp' may be used uninitialized in this function) which is make sense in case of 0xFD token.
Adding this driver to my project overflowed my RAM by like 11kB, any idea where all this extra memory allocation is coming from? I've skimmed through fastfs_sd.c and .h and can't see anything obvious.
Can't say really.. which controller are u using btw ?
Try not using my code. See the video and write yourself. That way you always know what u r doing and the places, where things get messed up.
