This is a PCI to USB bridge schematic that i was draw by hand from a PCI to USB card, the schematic use VT6212L to make bridge, the idear is that we can use microcontroler interface to PC through PCI slot by USB, ha ha it is too easy.
This software allows users to see how a serial async com port can be used to comunicate with a sync device (SPI). In this case, the software reads a low cost digital temperature sensor IC.
The model is Goal Programming and Serial Correlation with fuzzy concept.
This model can be used to solve some finance and economic problems.
The result can find the best and worse solution.
This is an example USB project showing how to interface an optical mouse sensor (the ADNS-2620) with a standard XP/Vista computer.
The TD-USB-01 board with a PIC18F2550 communicates with:
* the PC: USB 2.0 through a mini-B connector.
* the mouse sensor board: SPI over 4-wire flatcable.
