Pinout says the SPI pin:
MISO1 is PA6
MOSI1 is PA7
SCK1 is PA5
my CS pin is PA4
I am using SdFat Library with "Adafruit Fork by Bukk Greiman" and using SD card module with FAT32 card.
And using the SPI API like this:
SPIClass::SPIClass(uint8_t mosi, uint8_t miso, uint8_t sclk, uint8_t ssel)
my code:
Code: Select all
#include <SPI.h>
//#include <SD.h>
#include "SdFat.h"
#define SD_CS_PIN PA4
static SPIClass mySPI1(PA7, PA6, PA5, SD_CS_PIN);
#define SD1_CONFIG SdSpiConfig(SD_CS_PIN, DEDICATED_SPI, SPI_FULL_SPEED, &mySPI1)
// #define SD_CS_PIN PB12
// static SPIClass mySPI2(PB15, PB14, PB13, SD_CS_PIN);
// #define SD2_CONFIG SdSpiConfig(SD_CS_PIN, DEDICATED_SPI, SPI_FULL_SPEED, &mySPI2)
SdFat SD;
File myFile;
void setup() {
Serial.begin(9600);
Serial.print("Initializing SD card...");
if (!SD.begin(SD2_CONFIG)) {
Serial.println("initialization failed!");
return;
}
Serial.println("initialization done.");
myFile = SD.open("test.txt", FILE_WRITE);
if (myFile) {
Serial.print("Writing to test.txt...");
myFile.println("test123");
myFile.close();
Serial.println("done.");
} else {
Serial.println("error opening test.txt");
}
myFile = SD.open("test.txt");
if (myFile) {
Serial.println("test.txt:");
while (myFile.available()) {
Serial.write(myFile.read());
}
myFile.close();
} else {
Serial.println("error opening test.txt");
}
}
void loop() {
}i have checked the module and card is working fine on Arduino uno.
Can anyone please help me to get SPI SD working with my STM32F411CEU6 Blackpill board ? Thanks .
