the conmunication of MCU by USB2.0

STC12C5A60S2 具备一般51单片机不可企及的高性能，有片内ADDA，速度是一般51的8倍！-STC12C5A60S2 high speed,low price, with ADDA in chip!

模拟接受max7219的数据，主要是原系统升级，需要将原单片机驱动7219的数据接受并分析数据及命令。-simulation accept the data, major upgrade of the original system, the need for the original Microprocessor 7219 data accept and analyze data and orders.

这是msp430系列单片机的封装库，protel99se library，挺有用的哟。-This is the Controller Series MCU package libraries, protel99se library, quite the yo.

C8051F020的LCD的驱动程序，包括画图的一些例程-C8051F020 the LCD driver, including drawing a number of routines

基于8051F020,目的：用LM92器件实现数字化高精度温度测量-Based on 8051F020, Objective: LM92 devices with digital high-precision temperature measurement

With the program AD9854C.exe one can set and tune the frequency in CW-mode. For use as a receiver LO also IF can be given and the both possible receiving frequencies are printed on the screen. The level in Q-outputs can be varied by giving the wanted attenuation in dB. This function is done by controlling a 12b digital multiplier in the device. In this case the level decreases somewhat with increasing frequency as it does in DDS devices. Alternatively the inverse sinc correction can be chosen, in which case the output is flat and high. -With the program AD9854C.exe one can set and tune the frequency in CW-mode.
