im sorry for my bad English
I ‘m trying to fix a very long time to work SD Card module.
i have a STM32F103C8
and SD card module with SPI interface.
On my arduino nano Sd card module works very well, but on my STM32F103C8 not work at all ![]()
i dont understand where is problem, because i use SdFat.h, SD.h and nothing works.
there is code example:
#include <SPI.h>
#include <SdFat.h>
/*
* SD chip select pin. Common values are:
*
* Arduino Ethernet shield, pin 4.
* SparkFun SD shield, pin 8.
* Adafruit SD shields and modules, pin 10.
* Default SD chip select is the SPI SS pin.
*/
const uint8_t SD_CHIP_SELECT = SS;
/*
* Set DISABLE_CHIP_SELECT to disable a second SPI device.
* For example, with the Ethernet shield, set DISABLE_CHIP_SELECT
* to 10 to disable the Ethernet controller.
*/
const int8_t DISABLE_CHIP_SELECT = -1;

Do you supply the module with additional 5V or only the 3.3V from STM32 board?
I am using an SD card module without a 5V->3.3V converter, and it works OK.
but thanks for reply. I still need help.
No needs for voltage level-shifters because SDCards use 3V logic.
So, check your wiring again, and make sure proper pins are selected for SPI.
Using an STM32 you need only the adapter without any resistor or converter of any type.
I am not sure but maybe removing R1 to R4 and solderings the pads toghether, in other words substituting the resistors with solder, it will work. Maybe.
Instead I bought the SD->microSD adapter for the old RaspberryPi
Then I soldered a strip line to it on the pads. I got this idea from the Cave Pearl blog were it was used to build a datalogger with an Arduino micro 8MHz 3.3V.
(it can even run directly from 3V power supply if the ASM1117 output pin is disconnected/unsoldered)
recognizes Sdcard :/
now i solder pins like a
and still nothing works
I dont understand, maybe bad stm32?
Thanks for help guys i love you

You have two choices :
– one is to copy the library and modify all references to SPI to SPI2.
– try to use the SPI.setModule(2) before doing any calls to SD or SdFat.
