1）了解数模转换的原理及与8086的接口逻辑。

2）掌握使用DAC0832进行数模转换的技术。

1)设计DAC0832与8086CPU的硬件连接图，分配DAC0832的基地址为0FF00H。

2)设计DAC0832的硬件连接，编写程序，实现让0832依次输出方波、负向锯齿波、三角波、正弦波、，并不断重复。要求在示波器上可看到每个波形2个完整的波形。

-1) understand the digital-to-analog conversion principle and with the 8086 interface logic. 2) master DAC0832 digital-to-analog conversion technology. 1) design DAC0832 8086CPU hardware connection diagram, distribution the the DAC0832 base address 0FF00H is. 2) design DAC0832 hardware connection, programming 0832 turn output square wave, negative sawtooth, triangle wave, sine wave, and repeated. Requirements each waveform can see two complete waveform on the oscilloscope.
