Hi all,
since few weeks i have strang problem.
I'm using Pi4 with level shifter (as described here https://learn.adafruit.com/neo…ry-pi/raspberry-pi-wiring).
Everything works great untill now.
I see when, for example refrigerator starting, led make one flash at refrigerator starts, and pne flash when stops.
I measured voltage on gpio21..about 0,6v. I changed gpip to gpio19 on Hyperion management page, and this same voltage 0,6v as before on gpio21.
Then I force pull up gpio21 to high, after boot voltage 3,3v and on level shifter 5v
If i change on Hyperion gpio back again from gpio19 to gpio21 voltage again fall to 0,6v.
Could some on tell me what happend in my envairoment?
I use Libreelec v19.
Hyperion Aplha 9.
Pi4 4GB.
