Cyclone IV DE0-Nano USB in C#

I reviewed the schematic file. Clearly it's incomplete.
I don't see the FDTI component or the MAX II. Also the USB connector shows only as power input (page 14) without the typical t+ and t- differential USB signals.

Other than determining that the accelerometer talks I2C with the FPGA (F1 and F2 pins of the FPGA) I cannot find anything usefull in the schematics.

sindredit ,
is this the only schematics file ?

digi001,
fill free to give your input. I'm clueless.
 


Sorry,

These don't help to determine what feeds the FPGA side on the PC-FPGA interface.
The only good advice I can give you is to start implementing an I2C master on your FPGA using either VHDL or Verilog.
I'll try to find better schematics for this board.
 

shaiko, I have just finished a write I2C VHDL code :) :)
But, I have problems displaying the results in Modelsin and SignalTap. So I really dont know if it works or not ...
 

I cannot find on the schematic where connector for USB is?
 

If you haven't simulated it - most chances are that it won't work.
What's the problem?
What do you mean by : "I have problems displaying the results in Modelsin"
