hi all, pls help me with writing & reading & erasing of Compact Flash Cards. all suggetsions, links, codes are welcome. thanx in advance, rgds, kaushik
http://www.compactflash.org/ Usually, a CompactFlash card looks like a PCMCIA ATA disk drive, so you'll need file system code. The "portable file" CF cards, such as where you take the CF out of your digital camera and plug it into your PC card reader, are usually this sort. There are also "linear memory" flash cards, which are really just flash memory chips packaged in a cartridge, and require device-specific flash memory driver software. You would code for these much like you would for flash parts soldered onto your board.
i wish to use the Compact Flash Card for a presure scanner data logging system. i need to know how to interface 8051 & Compact Flash Card. this card i shall leter be inserting into a PC-CF reader & take the data on to a PC. pls help me with protocols/codes/etc thanx
Looks like you'll have to use a file system for sure. these links might help a bit. Although written for AVR processors, conversion shouldn't be that difficult. http://hubbard.engr.scu.edu/avr/avrlib/ http://www.yampp.com Could be helpful too: http://freedos-32.sourceforge.net/index.html Good luck...
