Hi all, I need to write some data to an SD card, so it can be retrieved on a=20 PC. Been researching, but have some lingering questions... - SD cards can be accessed in SPI mode, but what are the limitations of=20 that? Can I still write a files in PC-accessible format (FAT16, FAT32,=20 etc). And what is the *full* SD-card mode anyway? - Why do I need FAT32? If I can live with the 2GB limit, any Windows OS=20 can access FAT16 still, right? I ask because I understand that FAT16 is=20 much easier to implement. - Anyone have a link to a free FAT16 library? This looks promising, but=20 other recommendations appreciated...=20 https://www.marcusbannerman.co.uk/index.php/research/electronicspics/40-pic= -projects/76-fat32-library-for-pic18-devices.html - Anyone have a recommendation for a good book on the subject? I found=20 this, but the reviews don't tell me that it will get me a good=20 understanding on using SD cards with PICs...=20 http://www.amazon.com/Card-Projects-Using-PIC-Microcontroller/dp/185617719X= /ref=3Dsr_1_1?s=3Dbooks&ie=3DUTF8&qid=3D1339589318&sr=3D1-1=20 Cheers, -Neil. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
