Topic: Arduino due SD card and sensor issue (Read 1 time) previous topic - next topic



I wrote a sketch for reading and writing the ACCEl and GYRO sensor values into SD card.

the SD card module works on 5V and the sensor works on 3.3V.

The sensor wrks fine and displays the values in serial window when sd card is not connected....but when i power the sd card module with the 5V pin in arduino,my sensor values become 0 0 0 0 0...

What could be wrong here?? :smiley-confuse:


and one more... I used SPI to connect the sensors and SD card module with Chip select pins 4,10,52
