It would help if you identified stuff sent to the Serial Monitor.
Code:
Serial.print("distance: ");
Serial.println(distance);
is much better than:
Code:
  Serial.print(distance);
  Serial.print("\n");

Do this for everything you print to t...

same results. one thing, the chip speed is 3.3mhz, do i have that set correctly?

Code:
SPI.setBitOrder(MSBFIRST);
  SPI.setDataMode(SPI_MODE0);
  SPI.setClockDivider(SPI_CLOCK_DIV2); // max clock is 20MHz, so can set high speed

I have used the function atoi().

He Leute,
ich will ein Hygrometer mit Schimmelwarnsystem bauen.
Relativ einfache Sache: Arduino + LCD+ DHT22 + Extra Temperatur sensor.

Arduino kommt samt DHT an die Wand und an der kühlsten Stelle kommt noch ein Temperatur Sensor hin.

So kann ich aus ...

Nur vorwärts? Dann mit Transistor.
Auch rückwärts? Dann mit H-Brücke.

Go back to Reply #1. You have NOT gotten ridden of the useless gotos. You have NOT changed how you are reading data.

You are not getting good data from the card. Until you do that, you are wasting your time, and ours, trying to make sense of it.
