FYI, after successfully compiling all files in I2C opencore,I have problems with the simulation using Quartus2 simulator tool.I'm trying to write data as the steps below.
1.write clock prescaler (Addr 0 and 1)
2.enable core in control register (10000000 to Addr 2)
3.write data to transmit register (Addr 3)
4.start and write to command register (10010000 to Addr 4)
No any output on scl_padoen_o,scl_pad_o,sda_padoen_o & sda_pad_o
5.Reading the status register (Addr 4) shows 'Transfer in Progress' every
time.
Am I doing the right things?Some advices needed.Thanks a lots.
