ok, so i have a long project that I am working on, and this is the first time that I have had to work with microprocessors or anything of the sort. So I am still in the learning stage of things. I am working with the Seeedstudio SD shield, and I have already taken up pins 9 -15 (for an lcd display, kinda pointless, but it has its uses), so I have wired up the 3.3 V, the 5V, and two grounds to their respective pins, but I had to wire what was designed for pin D9 to D1 and D10 to D2 and so on. My question is will it matter what pins I wire the SD shield to, and does anyone have code snippets that could direct me on how to go about coding the program to write to the sd card ( i have coded in java, c++, matlab, and VB, but I am new to straight C).
in case you are curious I am working on a project to send a balloon to the outer atmosphere, collect data, take pictures, pop and come back down. I will be using 2 arduinos for this project, one as a sensor package, and the other as a gps interface that will have to transmit the location of the arduinos during the flight and when the sensors and everything else end up back on the ground.
thanks
