PX4 FLOW is a smart camera processing optical flow directly on the camera module. It is optimized for processing and outputs images only for development purposes. Its main output is a UART or I2C stream of flow measurements at ~400 Hz.

For help, run:

make help

To build, run:

  make archives # this needs to be done only once
  make

To flash via the PX4 bootloader (first run this command, then connect the board):

  make upload-usb

By default the px4flow-v1_default is uploaded; to upload a different version, run:

  make <target> upload-usb

Where <target> is one of the px4flow targets listed by make help.
