Modern industrial production data collection and scientific research on the require-
ments of increasing the transient signal measurement, image processing and other high -speed, high-precision measurement, the need for high-speed data acquisition, and the USB bus with high-speed transmission, hot plug, Plug-and-play features, has been in high-speed data acquisition systems have been more widely used.
In a PIC microcontroller as the core, a PIC microcontroller internal A / D convert-
r, designed USB100 modular design based on a data collection system.
Described in detail based on the USB100 module designed a data collection syste-
m and the overall design of the options, hardware and system software programming,
and so on. On the specific design of the circuit and the corresponding results, and are
given in the text of the principle of the hardware and software flow chart.
