Re: How to read raw data from MMC card?

[lee derek]

Hi, Aaron:
   I have gone through the VFS manager part in the palmsource website. 
However, I think my problem cannot be solved by VFS manager. I noticed that 
all the commands of VFS manager are based on "file", such as open a file, 
close a file, copy a file. But my MMC card only stores raw data of 
signals(two bytes of data represent 1 sampling value of signal). It is not 
in any known common file format such as JPEG,MPEG. So can you give me more 
detailed instruction on how to use that VFS manager? Thank you very much 
for your help!

Best Regards!

Derek

look at the Virtual File System (VFS) manager.
