摘要
以W77E58和MAX3100芯片为例,首先介绍了一种利用单片机I/O接口软件模拟串行外设接口(SPI)的方法.在此基础上从传输速率等方面理论论证了软件SPI口对相应芯片的负载能力.最后给出了实验验证电路,通过实验进一步验证了文中论证.文中介绍的方法可作为论证串行通信负载能力的一般方法.
Taking W77E58 and MAX3100 as example, the paper introduces a method of using I/O interface of singlechip to simulate Serial Peripheral Interface (SPI) at first. The loadability of the software serial peripheral interface is on data transmission rate. At last, the circuit is designed to demonstrate the theory. And the method can also be used as a general method of demonstrating the loadability of serial communication.
