Hello,

Hello,

I tried to do my design again based on your Qsys file and it did not work. I put the SCL and SDA on an oscilloscope, but the output was just noise, nor the clock in the SCL was generated. In Qsys, I added the OpenCores I2C component in Tools > Options > IP Search Path, is this correct? Do I need to do anything else? Because the other settings and procedures are the same as your design. Thank you so much for helping me.
