Reference Library SD 8:3 format

[bitfogav]

I notice that in the SD Card library it is mentioned that the string will be padded to 8:3 format, Can someone please explain what exactly this means?.. This might explain why when I read a byte from the SD Card, I get some extra bytes than I expect?.

The 8.3 comments apply to filenames... the lib supports old DOS-style names with an 8 char name and a 3 char extension (ie "FILENAME.TXT").

In SDLib.bas filenames are defined as

Code: Select all

' name structure...
Structure TName
   Dim Name As String(9)
   Dim Extension As String(4)
End Structure
Public Type TSDName = TName


and the padding is done in

Code: Select all

Sub ModifyFileName(ByRef pFileName As TSDName)

Thank you Jerry for taking the time to explain this, it is much appreciated..

In this case this wasn't the issue I thought and I found out that the few bits after each byte read from the SD Card was the new line command.. I think this has caught me out before..
