  1. Thx, That seems to work. Also, now I know where the examples are. Rob
  2. Hi, Thx for the response. I do have the usb-lite from the https://reference.digilentinc.com/vivado/getting-started-with-ipi/start connected (for debug). I want to add more uarts as communication buses. Currently, i don't want to use the pmod module. I just want the rs232 signals at the JA connector (it can be any of the JX connectors). Rob
  3. I am new to fpgas and Vivado. I am using the Arty A7-35T. I would like to do is connect a UART to the JA. I am trying to follow this example (https://reference.digilentinc.com/reference/pmod/pmodrs232/start) I have added the "X-Board VHDL Example", and it adds Rs232RefComp. I don't know how to connect the RxD and TxD to the pmod connector. Also, an explanation on how to use this would be helpful. Rob
