  1. I just plugged in this board and to test it out. My intent is to use it in a RS422 format, but will need to understand what changes I need to make later. I've opened up the arduino sketch and uploaded it to my AST-CAN485 from Sparkfun. I modified Digilent's the code so it uses the alternative software serial library. Other than that, it's all the same. When I run the code and open up the serial monitor, the loopback is actually happening in the hardware. I can unplug the looped wires and still get a message back. So the echo example code seems to not work properly. Any ai
  2. I am trying to receive 4 and drive 4 differential (rs-422) signals with an Arty board at a rate of 8 Mbit/s. These signals are going to be used in a noisy environment (which is why they are differential). I noticed that the Arty board's high speed i/o pins (PMOD JB and JC) "have their data signals routed as impedance matched differential pairs" according to the reference manual. Does this mean I would be able to use them as such with no further hardware required? What sort of precautions would I need to take to ensure that I do not damage any hardware and is there example code somewere, p
