Hi all, We are looking to use the Arty board for first tests on a machine vision system we are developing, which runs a 72 MHz parallel interface. For ease of testing I was planning to use the Arty board and its I/Os, but I see that it has 200 Ohm series resistors on each pin which will put a limit on the max allowed switching speed. Are there any specifications on the pins when it comes to speed? With 200 Ohms about 5-8 pF is maximum allowed after the resistor for a 72 MHz signal. Else, as I do not have the board yet, are the resistors easy to get to (silkscreen designators for correct identification) to replace the resistors manually with a lower value? Thank you for your time!
