i'm trying to program an uart to usb connection from my zedboard to my pc with simulink so i can read out/display and log data (8bit ufix) in tera term. I'm using matlab version 2013a on windows 8.1 with system generator. how do i constrain a serial output? I presume it's by using a "gateway out"-block but in the hardware guide it's not very well documented what i should write in it nor how the timing has to be constraint... Any help? thanks in advance!
