USB-DAQTM
The data logger / process controller that looks like a USB flash drive to a PC
Summary
USB-DAQ is a low cost data logger and process
controller. In normal operation it operates autonomously,
collecting data and providing control as required. An on-
board real time clock is provided.
When plugged into a USB port, USB-DAQ appears on
the PC like a removable disk. One file, CONFIG.DAT,
contains the application code. This file is created on the
PC from a Microsoft Excel spreadsheet. Other files may
be used for logging data.
USB-DAQ uses the Mass Storage Device (MSD) USB
profile. It does not require USB driver installation, and
so is immediately compatible with present and future
Windows, Linux and Mac operating systems.
USB-DAQ is generally available in 20-pin and 28-pin
packages. Both devices can use a 25AA1024 EEPROM
chip for moderate data storage (128KByte). The 28-pin
device can additionally use internal flash memory for
data storage up to 8KByte or SD card memory and
chips up to 1GByte. A 40/44-pin device, with the same
capabilities as the 28-pin device but with extra I/O, can
also be made available.
