Abstract |
This paper presented one possibility to development a simple and
small component count USB data acquisition system, used Delphi on
PC side to communicate. The main core of USB device is PIC18F4550.
This device affords an opportunity to switch different sensors and
registered their evi-dences via USB interface on PC. All received
data was storages in .txt file, with standard structure. The
software support for the data acquisition system device includes
the sources of the program on the chip and the Windows application
communicated with device as well as the driver. The real device was
pro-duced, tested and analyzed. The results are presented in this
article.
