串行外设接口(Serial Peripheral Interface)是一种同步外设接口,它可以便单片机与各种外围设备以串行方式进行通信以交换信息。外围设备包括Flash RAM,网络控制器、LCD显示驱动器、A/D转换器和MCU等。
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。
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.
通过SRU连接的外设包括但不限于:串行接口、SPI端口模块。
Peripherals connected through the SRU include, but are not limited to, serial ports and SPI ports block.
通用串行总线(usb)是目前PC外设接口的主流总线标准,并迅速在工业自动化仪器仪表中得到应用。
USB (Universal Serial bus) is a mainstream bus standard of PC peripheral interface, which extends its applications to industrial automatic instruments.
