* Not really Rust related, but has anybody here got an idea what's going on with my RS485 transceiver? I've rechecked all pins and they should be fine. Power supply is nice, stable and of the proper 3v3 voltage. But for some reason there's this ~200KHz block signal on everything. The A output is also at practically 0 volts. In this image I'm writing 0xAA at 9600 baud with auto DE management.
