Weigand data floods CSV file with 1 and 0
The R90 reader is constantly "receiving" data that is all 1 and 0. It floods in non-stop no matter what is or isnt around. When HF cards are placed next to it, the reader does not see anything other than the random length 1 and 0 entries. When no cards are anywhere around, it still shows massive numbers of random length entries flooding in from 1 numeral in length to dozens or over a hundred numerals in length. This does not cease no matter what is or is not around. Is the code still functional? I see that http://abyz.co.uk/rpi/pigpio/examples.html no longer appears to have the weigand code available. In fact, that entire domain appears to not be operational any longer.
This happened to me initially as well. The problem was the reader and the pi didn't have mutual ground. I had the reader plugged into a 12v power supply, and the pi was on a separate usbc power supply. Once I got a buck converter and powered the pi through the gpio, all that noise went away

Thanks for the advice. I have the pi powered via GPIO now instead of being connected via USB port. I have had a buck converter in the circuit since the beginning. However, I am still getting this same noise. No other card reads come through at all. All of this (pi and reader) is powered via 2 18650 batteries. I'm not sure why this is still failing in this manner.
