SMARTWAV 2

Serial Mode

9- Workspace# FAT/FAT32 Data Management Functions, Data

Logger -Serial Commands:

SmartWAV 2 uses the 14 audio channels also as workspaces# for those

next workspace# FAT commands, that means that up to 14

workspaces (0 to 13) could be used at the same time for file

management (the physical 14 spaces inside SmartWAV 2 could be

used as workspace or audio channels but not both at the same time).

As an example: the command “Open File” is used to assign a file to a

workspace#, only one file/object can be allocated at the same time

in the same workspace, the command “Close File” frees the

workspace.

This section is for Workspace# FAT Data Management Functions, all of

this section commands always require a file allocated/mounted on a

workspace# to work.

Note that all commands of this section always respond 2 types of

ACKs, first one is FAT access execution (ACK/NAK of the FAT ACK/NAK

List) and second one is general ACK ‘O’ or NAK ‘F’.

*Never remove micro SD card during any FAT operation as data could

be corrupted and damaged.
