DF Robot Serial Data Logger

Compared to the old MicroSD Card Module, this Gravity: Serial Data Logger can store data more conveniently, and supports direct data printing through serial port without additional codes.

The Serial Data Logger provides onboard 128MB Flash memory, no more TF card required. It comes with a USB function, which means you can directly connect it to a PC computer to read the stored files without using a card reader. Meanwhile, with the onboard LED indicator, data writing status can be viewed visually. And the onboard SAVE key makes it easier to store data into separate files.

Sample Code

Write data to the module through Serial.print, save a file every once in a while.

#define SPIN 6  //Connect to the module Pin S, trigger to save files at low level 
uint16_t i = 0;

void setup(void)
{
  Serial.begin(9600);
  delay(2000);  //To aviod data lost, delay a period of time to wait for the module to start 
  pinMode(SPIN, OUTPUT);
  digitalWrite(SPIN, HIGH);
}

void loop(void)
{
  Serial.println(String(i));
  i++;
  if((i % 10) == 0){
    digitalWrite(SPIN, LOW);
    delay(500);
    digitalWrite(SPIN, HIGH);
  }
  delay(300);
}
