Smart audio broke, on Matek f722mini, with bidir DShot

HrrrPippi commented 5 years ago

Describe the bug Followed the guide for setting up BF 4.1 RPM filters, and the snippit says that TX3 pin is broken, when using the Bidir DShot. My VTX(smart audio), just so happens to be connected to that pin.

To Reproduce Solder smartaudio to TX3, setup and use Bidir Dshot, and the fc will freeze whenever a lipo is plugged in.

Expected behavior Can you some how fix this bug, since the TX3 is located next to the VTX power, and video signal on the FC? I think others would have wired the same way i did.
