An embedded-hal no-std driver for the PMW3901 optical flow sensor.

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).
