i2c_verilog范例
但新的问题又出现了,我们的 rx 信号本身就是1bit的,如 果在判断第一个下降沿后,后面帧中的数据还可能会有下降沿出现,那我们会又产生一个start_nedge 标志信号。我们知道在 Verilog 代码中**标志信号(flag)和使能信号(en)** 都是非常有用的,标志信号只有一拍,非常适合我们产生像下降沿标志这种信号,而使能信...

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...
But in hardware it doesn't work :( When i see on FPGA's pin SDA and SCL are GDN-level and nothing happen.. Have anyone help me please :) Is any ideas why so? Source code and Simulated waveforms is Attached! Traduire Balises: Intel® Quartus® Prime Software multiple-...
This research paper presents the design and implementation of an SPI to I2C code converter using Verilog. The converter is designed to communicate between two devices that use the SPI or I2C protocol. The design process involved the use of Verilog Hardware Description Language (HDL) to implement ...
