I have the ultimate gps logger shield https://www.adafruit.com/products/1272 and i also have the barometric sensor BMP085 also from adafruit.
So the problem i am facing is that i can't get the sd card attached the gps logger shield to get data from both the gps and the barometric sensor at the same time .
I can get it to work only with the gps , and for the barometric sensor i attach an sd card to an ethernet shield and it works , but both separately.
Whenever i try to do both the program freezes and won't let the sd card initalization begin
here is my code
