Let's say I have almost a good news about sonar support in INAV: yesterday I flew terrain following mode with experimental INAV code. And did not crashed when shooting video below. I did crashed next code version, but that is only a minor detail, right?

  1. When shooting that video I did not touched throttle stick. Altitude control was 100% automatic
  2. It is US-100, not HC-SR04 ultrasonic rangefinder!
  3. US-100 was connected to Omnibus F4 Pro using experimental I2C interface with ATtiny85
  4. If you want to try it, here is the code. But be prepared to crash :)
