29. STM32CubeIDE SD CARD. SPI with STM32F103C8T6

[@NizarMohideen]

There are two additional info 1. Make sure sd card module gets 5V. Try separate power supply if possible 2. When you format SD card in windows10 with FAT32, select 4096bytes for allocation unit size.

[@htlee5371]

I tried this on F401CCU6,I had to change f_lseek(&fil, fil.fsize) => f_lseek(&fil, fil.fptr).At first,no file was generated.Then I saw this commet,I formatted the card to 4096 and connected 5 volts to vcc.Finally,It worked.👍👍👍👍

[@danhchucao3246]

Sir, I follow exactly what u did but when I use Usb cable which give 5V to sd MH-SD card module with sd card adapter, however I cant find the text file in the micro sd card although my system file of sd card was FAT32 and allocation size was 4096bytes. I use STM32F103C8T6, windows 10, and ST link v-2. Please help me, I am really losing patient on this

[@SiggyPony]

Thanks again for another good tutorial :) I wasted 6 hours on official tutorials trying to get an SD Card working with SDIO, gave up and came to try your SPI tutorial and it works :) Now I have it working on both my C8T6 and ZET6

Thank You Nizar you are the best! Your explanation is very clear and code is working [just change f_lseek function to -> f_lseek(&fil, f_size(&fil)); ], also thanks for SD reformatting info!

HELLO FROM POLAND NIZAR THANK YOU FOR WORKING CODE

[@carlosbarberis49]

Very good tutorial I tried it with the Nucleo STM32F446RE I had to make a few minor changes but got everything working just fine. The only question I have...Where do I find the additional SD card commands like: create directory, delete directory, delete file, rename file and append to file. Are these functions available within this library somewhere???

[@firebirdonfire]

I can't seem to get this to work at all with the Nucleo F446RE Board. Everything looks correct, but I can't get anything to write to the SD card... I'm using SPI2, pins PB13, 14, and 15. My CS Pin is on PB12. Everything programs, just no file on the SD card...

[@lc7827]

Code works fine. However, if you use 3.3V SD card module, you may need to add extra capacitor (47uF? or more) between 3.3V and GND. Without it SD seem to draw too much current and project no longer works.

Hi again bro, a question ,In which file is the function f_lseek(&fil, fil.fsize);? , because I can't find it in the files

[@NizarMohideen]

f_lseek(&fil, fil.fsize); is in a built-in library of CubeIDE. When Click Middleware → Click FATFS, it will kick in

Hey bro I saw a new change for the function f_lseek(&fil,fil.size()); if someone has a problem to intance the method fil.size try to use f_size(&fil) so the function f_lseek would be f_lseek(&fil,f_size(&fil));

1. Your program takes more memory than mcu memory. Reduce the size or use higher memory stm32. 2. You are using floating point without enabling float

Actually, the library creator "Lee Ji-hoon" used with spi2. It will work The link is below github.com/eziya/STM32_SPI_SDCARD/tree/master/STM32F4_HAL_SPI_SDCARD I suggest if you want SPI2 with STM32F103C8T6, try with SPI1 first.

I am not sure whether spi sd card is capable of writing 500 times in one second. You can put the data in a array buffer and then write it to sd card every one second. If there any data loss, you can reduce the data logging rate.

[@NizarMohideen]

Hi Thành Tiến, You can use separate files for each variables. For example Helpme = " nguyentienthanh"; you can use Helpme.txt and then save the variable without f_lseek(&fil, fil.fsize); It will overwrite in the beginning of the file. Another option is to use eeprom as I have shown in video-no-66 and video-no-67 of my KZbin channel. Thanks

If you are using STM32F103C8T6,It should work. To check the solder joints in pins PA4,PA5 PA6 PA7 ,5V AND G, you can connect LED's on it and run a simple blink program. If solder joints are good, make sure PA7 - MOSI / PA6- MISO Make sure the library file name spellings fatfs_sd.h / fatfs_sd.c Make sure you followed all the CUBEIDE settings given below Click connectivity → Click SPI1 For Mode select Full Duplex Master Set PA4 to GPIO_Output Click Middleware → Click FATFS Tick User-defined Configuration → Set Defines For USE LFN (Use Long Filename) select Enabled with static working buffer on the BSS For Max SS (Maximum Sector Size) select 4096 After all if it still not works, you can send me the main.c - user_diskio.c - stm32f1xx_it.c (3 files) to my email [e-mail], I can find any errors on it for you Good luck
