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.

Was such a helpful video. I made it work with a MSPm0l1306, by doing some small changes to implement my communication, but it was so helpful to understand how I would glue my applikation to the FATFS library. For some reason It wouldnt work in your user_diskio so i just moved all the functions into the diskio and then it worked. Do you have or would you make, a video on how to implement it with dynamic memory allocation?

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 ?
I commented this lines and it is working now, pay attention everybody that is anyone that is starting with this example to comment this if you want to put the sd card in your pc to see the data that was written on the sd card. I used a 16GB San Disk Ultra MICRO SD HC I and now worked. I think that cards with 2GB not work because i tested with 2 of then, maybe i should make the same thing that i did when formatted the sd card. The codes of control tech work really, but if you download the already code you have to follow the comments of the video about change MAX_SS to 4096 and USE_LFN to ENABLED WITH STATIC WORKING buffer on bss . When you format the SD CARD should make with FAT 32 and choose 4096 bytes. And slow the speed of SPI to 2.25MBps and i put external 5V power. Control tech have very good videos. I don´t like when my things not work, sorry about my declaration that i did before. Thank you very much for this video.

Do you have recommended changes in the above code to enhance performance? Thank you !
Thanks for the video!! Worked here in my STM32L152 Disco board, with minor adjustments. I was able to create files, write and read. However, a few weird outcomes: total and free sizes result with a dot before the number (numbers seem correct); also, the current version of FIL struct in ff.h doesn't seem to have the .fsize field, so I haven't found a way to read the correct amount of bytes yet. Thanks again!
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.
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.
"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.
Controllers Tech we did exactly what you did and when we step into the f_open it goes directly to res != fr_ok. Do you know why? Actually I think only the f_mount works fine.

Out of the main function ? Means where ? Only the main function gets executed... You can write another function outside the main but you need to call it at some point in the main function
It's the same for other STM, I use the stm32l432kc and it works fine. For doing so, you have to change the name to the library according with your microcontroller in the fatfs file. For example: #include "stm32l4xx_hal.h" I included this in my case in yours: #include "stm32f3xx_hal.h" I think

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.

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?
Hi, Is there anything else to do, except replacing libraries with old one, to avoid getting FR_NO_FILESYSTEM? Iam using F303RE board
Hello,
Everything working well. But i need to log 10 bytes of the data after every 5 milli seconds and this should be done for 24 hours,
The SPI hangs (remains in busy and locked state)after some times and i can only write for few mins of data.
Please suggest
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
Thank you very much the best tutorials for stm32 in RUclips
Hello, I have a question. I'm using FreeRtos and Timer 1 as the source, so there is no SysTick_Handler fuction in stm32f1xx_it.c. Where would I put the FatFsCnt check in this situation?

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
Was such a helpful video. I made it work with a MSPm0l1306, by doing some small changes to implement my communication, but it was so helpful to understand how I would glue my applikation to the FATFS library. For some reason It wouldnt work in your user_diskio so i just moved all the functions into the diskio and then it worked.
Do you have or would you make, a video on how to implement it with dynamic memory allocation?
Every 512th character in the file is in error. This must be an indication of the block size being in error or something. What do I have to do, format the SD card? It says its block size is 512

I will take a look at it again...

Just use the arduino code. What's the issue ?
thank you sir can you guide how the usb interfacing
I commented this lines and it is working now, pay attention everybody that is anyone that is starting with this example to comment this if you want to put the sd card in your pc to see the data that was written on the sd card. I used a 16GB San Disk Ultra MICRO SD HC I and now worked. I think that cards with 2GB not work because i tested with 2 of then, maybe i should make the same thing that i did when formatted the sd card. The codes of control tech work really, but if you download the already code you have to follow the comments of the video about change MAX_SS to 4096 and USE_LFN to ENABLED WITH STATIC WORKING buffer on bss . When you format the SD CARD should make with FAT 32 and choose 4096 bytes. And slow the speed of SPI to 2.25MBps and i put external 5V power. Control tech have very good videos. I don´t like when my things not work, sorry about my declaration that i did before. Thank you very much for this video. And i am sending my contribution to this site.

Thank you !
Thanks for the video!! Worked here in my STM32L152 Disco board, with minor adjustments. I was able to create files, write and read. However, a few weird outcomes: total and free sizes result with a dot before the number (numbers seem correct); also, the current version of FIL struct in ff.h doesn't seem to have the .fsize field, so I haven't found a way to read the correct amount of bytes yet.
Thanks again!
ERROR!!! in mounting SD CARD... how get I solve this problem
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.

How to make a file with increment filename?
Can i make it with same configuration like in your video?
File name is a string.

Thanking you sincerely regarding our tutorial. can you please guide Can TRANSCEIVER MCP 2551 WITH STM32F4
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
Is there a way to send data with DMA ?
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?
Is it working if we do not use USART? And where do you connect those USART pins to?
Of course it works without uart. Uart is just to check, its like verbose in linux 😀. Pins are connected to the Tx and Rx pins..
Controllers Tech we did exactly what you did and when we step into the f_open it goes directly to res != fr_ok. Do you know why? Actually I think only the f_mount works fine.

It's the same for other STM, I use the stm32l432kc and it works fine. For doing so, you have to change the name to the library according with your microcontroller in the fatfs file. For example: #include "stm32l4xx_hal.h" I included this in my case in yours: #include "stm32f3xx_hal.h" I think
