该功能用于初始化SPI通信。 设置通信时钟。时钟信号由主机产生，从机不用配置。但主机的SPI时钟频率应该在从机允许的处理速度范围内。 ~ SPI_CLOCK_DIV4，4分频（默认配置）； ~ SPI_CLOCK_DIV8，8分频； ...

Quick, how do you wire up an SPI bus between a microcontroller and a peripheral? SCK goes to SCK, MISO goes to MISO, and MOSI goes to MOSI, right? Yeah. You’ll need to throw in a chip select pin, but ...

Arduino enthusiasts or those looking to learn more about programming with Arduino and electronics-in-general may be interested in a new Kickstarter campaign and Arduino compatible 42-Digit SPI Keypad ...

Interfacing with the outside world is a fairly common microcontroller task. Outside of certain use cases microcontrollers are arguably primarily useful because of how easily they can interface with ...
