PixRacer stabilized with PMW3901 optical flow

To work around the fact that the PixRacer does not have an exposed SPI port, we use an Arduino that emulates the PX4FLOW sensor on the I2C bus. The above is using the LPE estimator.

Hello there! Is there a cool official like way to get started with drone building and stuff? Thanks in advance :)

Hi, I`ve question. you tell... Finally, note that since the flow deck has no IMU, the gyro data is zeroed out. This means that gyro compensation will not work unless reprogrammed to use the PX4's main IMU (which I recommend anyhow.) This requires modifying the Kalman filter in the PX4, contact me for details on how. ... If I want to implement this features, the body data in PX4 is obvisuly Zero, ¿Could you tell how can I reconfigured the kalman filter to void this failure? you idea is greath, I wish to complete this improvment.
I`apreciate it a lot.

Hi I am trying to implement arduino librairies of the PMW3901 on STM32 microcontrolers but I have a hard time finding accurate datasheets, can somebody send me some of their SPI trames.
