State Diagram: Presents a state diagram illustrating the behavior of the Finite State Machine (FSM) used in the I2C implementation. Results : Displays the simulation results demonstrating the successful operation of the I2C protocol.

An I2C (Inter-Integrated Circuit) controller module implemented in Verilog for facilitating communication between a master device and slave devices using the I2C protocol. This project is designed to handle basic I2C operations, such as sending a slave address, transmitting data, and receiving acknowledgment.

The designed I2C protocol is based on FSM (Finite State Machine) model. The different states are explained as follows. Figure 2:FSM model of I2C State 0 - Idle: No operation. Both SCL and SDA lines are pulled up to high level through pull up resistors as shown in Figure 1. State 1 – Start: The SDA line switches from a

2022年5月17日 · 主要内容包括简述I2C总线的特点；介绍用FPGA中FSM开发I2C总线模块时的设计思想和实现过程；给出并解释了部分用Verilog HDL描述I2C总线初始化SAA7111和SAA7121的程序，最后在QuartusII中进行了I2C总线主从模式下的时序仿真和用其内嵌逻辑软分析仪SignalTap II完成了硬件调试。

The FSM (Finite State Machine) for I2C is designed according to its communication protocol, Features and functionality. Various steps of communication are represented by the states of FSM as shown in Fig. 4.

I2C is a bidirectional 2-wire bus designed to enhance hardware efficiency and increase simplicity of the circuit. This protocol bolsters multiple masters (which is a limitation with SPI communication) and multiple slaves and also allows communication between faster and slower devices by a serial data bus (SDA) without data loss.

The document discusses implementing the I2C communication protocol using a finite state machine model in Verilog HDL. It describes the different states of the FSM model for I2C and provides timing diagrams for read and write operations. The functionality of the designed FSM model is verified through simulation using Xilinx ISE tools.

2024年1月15日 · 最近一个项目需要做I2C的slave，在opencores.org上面找到了一个I2C的代码，不过是master的。 下载来看看，发现里面有一个I2C slave的行为级代码。 于是自己根据这个代码改写了一个I2C slave RTL的代码，并修改了...

The objective of the I2C controller core is to establish and synchronize data transfer between ADC and FPGA. The design of the I2C controller is accomplished through Finite State Machine (FSM) using VHDL hardware description language and hardware implementation is performed on the digital development platform with Artix-7 TM FPGA from Xilinx.
