ok just did some more testing I have two 7i76 cards connected up now and everything works (using second connector on 5i25 for extra 7i76)
I am wondering if I have broken the 7i77 I have which I ran 5v backwards through. is this possible to do and if it is would I expect a communication error as a result of it? If I have broken it that would be a bit sad haha On Sat, Nov 21, 2020 at 9:40 PM andrew beck <andrewbeck0...@gmail.com> wrote: > ok just did some testing > > when I flash the 5i25 with this 5i25_7i76x2.bit file it all works fine > > this is just with the 7i76 connected up > > when I try to connect up the 7i77 and flash this bit file > (5i25_7i76_7i77.bit) into the 5i25 I get a issue > > the 7i77 is coming up with a red led though in CR16 I read in the manual > that this goes red when there is a communication error with 5i25. > > now I have just discovered that I powered the 7i77 with 5v and had the > polarity wrong so was trying to send -5v into 7i77.
