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.
USB的全稱是Universal Serial Bus,USB支持熱插拔,即插即用的優(yōu)點,所以USB接口已經(jīng)成為MP3的最主要的接口方式。USB有兩個規(guī)范,即USB1.1和USB2.0。 USB1.1是目前較為普遍的USB規(guī)范,其高速方式的傳輸速率為12Mbps,低速方式的傳輸速率為。。。
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.
