In SPI mode, the I2CSPI-CTRL controller can operate as either a controller (master) or target (slave), offering full-duplex communication. In master mode, it initiates data transfers and controls the clock (SCK), while in slave mode, it operates under the control of an external master devi...

This paper demonstrates how I2C Master controller transmits and receives data to and from the Slave with proper synchronization.The module is designed in Verilog and simulated in ModelSim. The design is also synthesized in Xilinx XST 14.1. This module acts as a slave for the microprocessor which...

SPI总线提供一个MHz级的同步串行连接。由于要求嵌入式系统支持不断增长的协议和接口,针对常用协议的桥接设计为此提供了削减开发时间和成本的解决方案。这个参考设计实现了SPI master到I2C slave的桥接。用作为微控制器的标准I2C总线和SPI总线间的接口。使得微控制器可以直接通过其I2C总线与SPI总线进行通信。

3 verilog HDL 代码设计 由于I2C 总线传输协议可知,I2C 在传输过程中存在着几个固定的状态,因此我们采用同步状态机来设计I2C 模块。主状态机共有5个状态:空闲(Idle ),开始(Start ),发送数据(Tx ),接收数据(Rx ),停止(Stop )。图3 I2C 模块主状态机状态转移图 Idle :I2C 总线处在空闲状态。Start :当...
