I am using SD card module with ESP32-S3_DEVKIT1. My goal is to check for inserted card. Code is easy enough but when I do the SD.begin(my_SD_CS_pin), when the card is not present, I get a bunch of SDcommand messages from SD_diskio.cpp out the USB serial monitor port. How can I suppress these message (the ones beginning with the bracketed numbers)?

THANKS!

Here is what the serial traffic looks like:

Code: Untitled.cpp Select all

waiting for SD card





Found SD Card



SD Card Type: SDHC

SD Card Size: 30543MB





config.ini found.

Here is what my code looks like:

Code: Untitled.cpp Select all


bool CheckForSDCard()

{

  if(!SD.begin(CS_PIN))

  {

    bSDCardPresent = false;

    return 0;

  }

  else 

  {

    bSDCardPresent = true;

    return 1;

  }

}



void setup()

{

  Serial.begin(115200);



  Serial.println("Hello World!");



  while(!CheckForSDCard())

  {

    Serial.println("waiting for SD card");

  }



  Serial.println("\n\nFound SD Card\n");
