Re: Galileo help needed

Thank you flummer, that worked a treat.

Now I'stuck and wondering would you or anyone else have any more sugeestions.

I did get the code working and it saves a file pic.jpg to the memory card but while it's running in the Serial window it seems to keep on scrolling and it's blank. Also the file itself is 0KB. Reading through the code I'm not sure if it tells it to stop taking pics and write. There is a function there but does it call it?

Can you help?

// Note:
// 1. SD must be formated to FAT16
// 2. As the buffer of softserial has 64 bytes, so the code read 32 bytes each time
// 3. Please add the libaray to the lib path

//  * SD card attached to SPI bus as follows:
//** MOSI - pin 11
// ** MISO - pin 12
// ** CLK - pin 13
// ** CS - pin 4
