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. I may have stuffed it I suppose. all the jumpered are set correctly but I may have created a problem for myself any thoughts or ideas sing out. I have another brand new 7i77 I will try now and just see if that one works. . the existing 7i77 worked last week when I was testing which is why I didn't double check wiring lol On Sat, Nov 21, 2020 at 9:23 PM Gene Heskett <ghesk...@shentel.net> wrote: > On Saturday 21 November 2020 02:17:55 andrew beck wrote: > > > I have two plugs connected from 5i25 > > > > The cable to the 7i77 is a known good cable that was working last > > week. > > > > I think I might have my cables crossed.
