Hello, Dear All
I'm very very new as an FPGA beginner!! (self-learning about a month till now)
I would like to use Redpitaya Stemlab125-14 FPGA board to acquire signal synchronizes with an external trigger source simultaneously very fast.
I was following this tutorial Project 5 by Anton Potočnik.
Says in the Trigger Hierarchy section in the post, and confused with this little problem for several days.
How can I use an external trigger source from the other FPGA such as DE0-nano by exp_# io ports,
It didn’t seem like just easily connect the exp_tri_io port direct to the trig port of Averager IP
because I always get infinite digital 1 signal(always keep triggering ON) if I connect to the trig port, not responding to my 0 ~ 3.3V trigger source from DE0-nano, it seems like the GPIO0 is getting used as a configs register?? I've been re-write the averager IP block's Verilog for few weeks and it works very well, but just not synchronizes the external trigger I gave.
THANKS to replying to me!!
