8098单片机高速输出口HSO的两种特殊用法

8098单片机以其丰富的软件和硬件和硬件资源为用户提供了极大的方便.本文介绍两种直接利用8098的高速输出口HSO来实现E-PROM编程接口和实现多路D/A转换接口,是两种经济实用的接口电路.

According to 8098 SCP structre features,a multiple D/A converting method useing HSO and PWM function is introduced in the paper. This method prosesses the advantages of simple structure,casy programming, aut-matic refreshing and it shares less time, of CPU. The working principle and the hardware and software rea lization are also introduced in detail.
