You need some application on the PC that can open the file, and stream it, via the serial port, to the Mega. The Mega then just copies the data to the SD card.

Can't your PC write directly to the SD card?

Yes I can !!! But I want to do it this way because the link sprite camera that I got to take pictures is not working .I am right now doing a project for my school.I want to transfer images using CC1101 transceiver . But because the camera is not working I am stuck . I am hoping i can just copy some images into the SD card using Arduino and transfer the images hence emulating the actual requirement. What application are talking to open the file in PC ? I know how to open the file and write test to it . Bu i need to know how to copy images /

Hello everyone,

I am trying to connect the arduino Mega2560 with the sparkfun microsd shield.

After making the proper soldering i add the shield to the arduino but i do not manage to run CardInfo.

I made the following changes in the default code:

const int chipSelect = 8;

   pinMode(53, OUTPUT);     // change this to 53 on a mega

I receive the same message continously, Init failed and the 3 possible sollutions

I use this with my Mega 2560 and sd card: const int chipSelect = 53;
