Hello,
I’m trying to get UART access to my receivers.
Don’t know exactly what to do with it next, at this stage it’s experimental let’s say.
First step was identifying candidates on the PCB.
I found some candidates (4 pins, one of them on GND).
Then I was looking for some activity on one of the pin after boot.
And here’s my problem: all the pins stays on 3.3V after boot.
I’ve read about UART can be blocked. Is there any hardware solution to unblock it?
This is something new to me, so don’t be too hard :-)
Greetings
