ESP32: SD-card on HSPI port

folkertvanheusden commented 7 months ago

Hi,

I would like to connect my SD card reader to the HSPI port on an WEMOS32 as I also have an Ethernet board connected to the VSPI port. So I connected SCK to 14, MISO on 12, MOSI on 13 and SS on 15. This doesn't work unfortunately: SdError: 0X17,0X7F. Is this supposed to work? If not: can I connect both SD & Ethernet to the "primary" SPI port? (with each their own SS of course)

#define SPI_DRIVER_SELECT 1
#include <SdFat.h>
#include <SPI.h>

#define MY_SS 15
SPIClass spi_sd(HSPI);
#define SPI_CLOCK SD_SCK_MHZ(16)
#define SD_CONFIG SdSpiConfig(MY_SS, SHARED_SPI, SPI_CLOCK, &spi_sd)

SdFs sd;

void setup() {
    Serial.begin(115200);

    Serial.println(F("Init SPI for SD reader"));
    spi_sd.begin(14, 12, 13, MY_SS);  // SCK, MISO, MOSI, SS

    if (sd.begin(SD_CONFIG) == false) {
        Serial.println(F("SD card init failed"));
        sd.errorHalt();
    }

    Serial.println(F("Go!"));
}

void loop() {
    sd.ls(LS_DATE | LS_SIZE);
    delay(1000);
}

I can't help since I have little experience with WEMOS32.

why? WEMOS32 is just another ESP32 ...

Because I don't use ESP32 In my projects. I am not sure I can even find a ESP32 board.

SdFat by default uses a wrapper for the ESP driver that someone provided as a work around for a bug a number of years ago,

You could try editing SdFatConfig.h and changing this define so the wrapper is not used.

#define SPI_DRIVER_SELECT 1 // default is zero.

Got it to work with different pins.
