spi协议英文详解

In this presentation, we will look at what the Serial Peripheral Interface, otherwise known as the SPI, is. and how it is used to communicate data to and from the PICmicro microcontroller.

SPl is frequently used when few 1/O lines are available, but communication between two or more devices must be fast and easy to implement.

In this presentation, we will discuss the following topics: We will first cover an Overview of SPI This section of the tutorial will introduce you to SPI and its concepts.

Next, we will examine the use of SPI on the PICmicro MCU.

The details of how SPI is implemented on a PICmicro device will be examined.

Then, a Code Walkthrough will be given.

The walkthough will explore code for both an SPI Master and SPI Slave. The example will have the Master generate data for sending to the slave.

Finally, there will be a few resources given at the end of the presentation. These resources will allow you to explore in more detail the SPI interface
