I got my SD shield in yesterday and soldered in the headers, I have checked and rechecked the solder joints under a magnifing glass and see no soldering errors. But I keep getting the same error.

Here is my sketch.

while (FreqCounter::f_ready == 0)

Serial.println("Done");

Serial.print(cnt++);
Serial.print(" cpm: ");
Serial.println(frq);
// write 100 line to file
for (uint8_t i = 0; i < 100; i++) {
writeString(file, "line");
writeNumber(file, i);
writeString(file, " millis = ");
writeNumber(file, millis());
writeCRLF(file);
}
// close file and force write of all data to the SD card
file.close();
delay(1000);

digitalWrite(pinLed,!digitalRead(pinLed)); // blink Led

}

Which object are you trying to call writestring on?

I have checked and rechecked the solder joints under a magnifing glass and see no soldering errors

Soldering is rarely a cause of compiler errors

frq I believe its the data I want to save as a data logger, I am kind of new at this. :slight_smile: :slight_smile:

You are trying to call two functions, writeString and writeNumber, that you have not defined.

Your problem is kind of like a cave man trying to call his neighbor before the telephone was invented, complaining I don't understand why I can't do this.
