A Word Variable, which contains the SRAM address (pointer) , to which the information of the Drive should be written

The Identify Drive Function returns the parameter information (512 Bytes) from the Compact Flash Memory Card/Drive and writes it to SRAM starting at the address, to which the content of the variable wSRAMPointer is pointing. This information are for example number of sectors of the card, serial number and so on. Refer to the Card/Drive manual for further information. The functions returns 0 if no error occurred. For Error code see section Error codes.

 

Note: For meaning of wSRAMPointer see Note in DriveReadSector

= Partial Example =

 <source lang="bascomavr">
Dim bError as Byte
Dim aBuffer(512) as Byte' Hold Sector to and from CF-Card
Dim wSRAMPointer as Word' Address-Pointer for write

' give Address of first Byte of the 512 Byte Buffer to Word-Variable
wSRAMPointer =VarPtr(aBuffer(1))

' Now read the parameter Information from CF-Card
bError = DriveGetIdentity( wSRAMPointer)
