# pmw3901-ehal
Rust no_std embedded hal driver for the
pmw3901 optical flow sensor hardware.
## Notes
- The only supported mode for debugging is RTT with the `rttdebug` feature.
This is because common flight controller hardware that uses the sensor
only provide a SWD interface (no easy ITM solution).
