Filip Posted September 6, 2015 Report Share Posted September 6, 2015 Hello, at last I have time to play with FPGAs .. I wanted to connect arduinos trough serial to the Duo which then talks to the PC. I used the DesignLab example for "Multiple serial ports " and looked also in http://gadgetfactory.net/learn/2013/11/15/papilio-schematic-library-10-serial-ports/ the Duo can talk to itself via the UARTS , but when I connect an Arduino (to uart 1 or change the code ..)there is no communication. I have only one Duo can someone else test ? Ediit :int inByte = 4;Serial1.write(inByte);Serial write works only with a constant , but print does not work at all. thanks,Filip Quote Link to comment Share on other sites More sharing options...
