  1. Well, I am not an interface expert, but there are series termination issues with resistor values in many ways. I think mostly people will drive wires like SPI, I2C and those require pull ups of around 120 Ohms and more. So implementing a 50 Ohms can not be usefull there. In the opposite it is possible to bridge a resistor with higher value easily by a parallel resistor. Maybe this is a solution. P.S. I like those PMODs, because you can quickly assemble a system for test. Recently I needed a permanent I2C-Trigger and was able to do that this way in an hour.
  2. Moreover I would recommend to start with VHDL and write plain digital electronics rather than starting with CPU designs. Honestly it is a kind of silicon abuse to downgrade it to a CPU :-)
  3. Interesting. Thanks for that. To answer the question regarding BRAM? I wonder if it is possible to handle a large image in BRAM , because of the size. Maybe such a thing like coded colour.
  4. Thanks for sharing this project and information. I have a question regarding the VGA-options: What is the highest frequency for the pixel clock which can be used together with this VGA option board?Is
  5. 25MHz pixel clock is not that high, right? What would be the highest pixel clock which can be used together with the Arty and these Ports?
  6. could be plz briefly describe, what is the advantage of this OS?
