1.1.SPI协议概括. SPI，是英语Serial Peripheral interface的缩写，顾名思义就是串行外围设备接口。是Motorola首先在其MC68HCXX系列处理器上定义的。SPI接口主要应用在 EEPROM，FLASH，实时时钟，AD转换器，还有数字信号处理器和数字信号解码器之间。 The W25Q64FV support the standard Serial Peripheral Interface (SPI), Dual/Quad I/O SPI as well as 2-clocks instruction cycle Quad Peripheral Interface (QPI): Serial Clock, Chip Select, Serial Data I/O0 (DI), I/O1 (DO), I/O2 (/WP), and I/O3 (/HOLD). SPI clock frequencies of up to 104MHz are supported allowing 支持Quad SPI的闪存芯片通常支持Dual SPI，而且单、双和四线SPI也是引脚兼容的。以上就是英锐恩单片机开发工程师分享的SPI协议：单线，双线，四线SPI的区别。英锐恩专注单片机应用方案设计与开发，提供8位单片机、16位单片机、32位单片机、运放芯片和模拟开关。 The W25Q32FW support the standard Serial Peripheral Interface (SPI), Dual/Quad I/O SPI as well as 2-clocks instruction cycle Quad Peripheral Interface (QPI): Serial Clock, Chip Select, Serial Data I/O0 (DI), I/O1 (DO), I/O2 (/WP), and I/O3 (/HOLD).
