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: [Select all] [Expand/Collapse]

Here is what my code looks like:

Code: [Select all] [Expand/Collapse]

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");
  
// ETC, ETC, ETC
