Hi all
I am trying to write 8 bits FPGA signal to GPIO or AUX IO of USRP 2953R, but it seems that the AUX IO signal output I observed from oscilloscope is not as I expected, I want to know if I have problem with my code. I am using LabVIEW communication design suite and USRP 2953R to implement it. I tried to google or search in the Labview community, but cannot find too much information.
My Idea is to counter the clock, if it is the 27504th sample out of 30720 samples, then I add one to counter, and I mod the counter with 128, so that I can get 8 bit integer. I split the 8 bit integer into 8 independent Boolean bits, and write them to 8 separate AUX IO from 0 to 7.
Attached is part of my code of writing to AUX IO from FPGA, I wonder if someone can help me to check the problem.
My understanding is that I will write to the AUX IO every clock cycle, but since the Boolean value will not change for a long time, the IO will keep a constant value for a long time. Please correct me if I am wrong. Thanks!
Best Regards
