Interfacing SPI Peripherals to the MAX7651 Processor

资料介绍
Abstract: This article explains how to interface a GPIO port to an SPI peripheral. It defines the basics of the SPI protocol, the signals and the four transfer variations for the SCK signal. A software routine is included to implement the SPI interface using the MAX7651, a flash programmable 12-bit integrated data-acquisition system.

Interfacing SPI Peripherals to the MAX7651 Processor

Abstract: This article explains how to interface a GPIO port to an SPI peripheral. It defines the basics of the SPI
protocol, the signals and the four transfer variations for the SCK signal. A software routine is included to
implement the SPI interface using the MAX7651, a flash programmable 12-bit integrated data-acquisition
system.


Introduction

The SPI bus is a 4-wire serial communications interface used by many microprocessor peripheral chips. The
MAX7651 microprocessor does not include dedicated hardware ……
