Basic Operation
USB-DAQ contains a FAT file system on which files can
be stored. When plugged into a Windows, Linux or Mac
PC, USB-DAQ looks like a flash drive and files can be
directly accessed without the need to install drivers or
software. The file can be stored in internal memory (8
kByte), external 25AA1024 memory (128 kByte), or SD
cards or chips up to 1 GByte. The PC can create, read,
write and delete files and subdirectories as required.
In addition to functioning as a flash drive, USB-DAQ has
a data acquisition / process control engine and a real
time clock that allow it to function autonomously when
not connected to the PC. A file named CONFIG.DAT in
the root directory controls the chip’s function when
operating in this mode. This file is created in a Microsoft
Excel application and includes instructions to execute on
startup, and when an interrupt or real-time-clock event
occurs. USB-DAQ can read and write to up to four files
in the root directory; it does not create them, delete
them, or change their length.
When a file in the root directory is modified by the PC,
USB-DAQ notes the modification date and time data in
the directory entry and use this information to set the
time on the real time clock.
