5、SPI协议的最后一个SPI_CLK也要保证完整,有低有高,不能只有一半,如将SPI_CLK拉高之后不拉低就将SPI_CS信号拉低。 example: verilog EEPROM--SPI interface View Code tb: View Code 对于I2C的接口: 1、读写之间按I2C的协议进行就可以。 2、在读取数据时候,master在接收完8bit数据之后,需要给从机发一个A...

SPI:SPI(Serial Peripheral Interface)串行外设接口,全双工,同步串行 1、SPI总线由三条信号线组成:串行时钟(SCLK)、串行数据输出( SDO)、串行数据输入(SDI)。SPI 总线可以实现多个SPI设备互相连接。提供SPI串行时钟的SPI设备为SPI主机或主设备(Master),其他设备为SPI从机或从设备(Slave)。主从设备间可以实现全双工通...
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...

Hello. Im in the stages of designing an I2C interface to the audio codec on my fpga. Its very simple, as im new to verilog and still in debugging stages. One snag is when Im attempting to read certain bits of a parallel input. My code, in state s2, seems alright but it goes unsta...
The synchronous I2C interface is a block that interconnects an APB bus. The APB – I2C Bridge interfaces to the APB bus on the system side and the I2C bus. The APB interface is used to easily integrate the Bridge Controller for any SOC implementation. The APB – I2C is a master/slave ...
The I2CSPI-CTRL is a compact and versatile serial interface controller supporting both the SPI (Serial Peripheral Interface) and the I2C (Inter-Integrated Circuit) protocols.
