    • RE: my M5StickC Plus can't read micro SD

      Thank you for the advice.
      and, I'm very sorry.
      the connection and sketch I indicated was wrong.
      confused.

      Finally I reffer and correct information are here.

      Maybe, it is almost dead copy of the refference page.

    • my M5StickC Plus can't read micro SD

      Please help a beginer me.

      I tried to set up my M5StickC Plus can read micro SD card.
      However, it didn't work.
      "Card Mount Failed" was displayed.

      This is the connection and my code.

      // referred to below
      // https://lang-ship.com/blog/work/m5stickc-spi-sd/
      #include <M5StickCPlus.h>
      #include "SD.h"
      // PIN assign
      enum { spi_sck = 0, spi_miso = 26, spi_mosi = 32, spi_ss = 33 };
      void setup()
      {
        // M5Stick initialize
        M5.begin();
        M5.Lcd.setRotation(3);
        // SPI initialize
        SPI.begin(spi_sck, spi_miso, spi_mosi, spi_ss);
        // SD card initialize
        if (!SD.begin(spi_ss)) {
          M5.Lcd.println("Card Mount Failed");
          return;
        }
        // SD card classification
        uint8_t cardType = SD.cardType();
        if (cardType == CARD_NONE) {
          M5.Lcd.println("None SD Card");
          return;
        }
        M5.Lcd.print("SD Card Type: ");
        if (cardType == CARD_MMC) {
          M5.Lcd.println("MMC");
        } else if (cardType == CARD_SD) {
          M5.Lcd.println("SDSC");
        } else if (cardType == CARD_SDHC) {
          M5.Lcd.println("SDHC");
        } else {
          M5.Lcd.println("UNKNOWN");
        }
        // SD card volume
        uint64_t cardSize = SD.cardSize() / (1024 * 1024);
        M5.Lcd.printf("SD Card Size: %lluMB\n", cardSize);
      }
      void loop() {
      }
      

      Perhaps, the issue caused by SD.begin(spi_ss).
      Maybe it returned false everytime.
      But I have no idea for fix it.
      Give me a clue please.

      PS.
      the SD card and SD card shield I use are below.
      but, not only these, also I used any other I have, and same result.
