PX4Flow library for Arduino

A small library wrapping the Wire I2C calls to a PX4Flow Optical Flow Tracker.

Usage

• Clone this repository on your local system
• Add the PX4Flow folder in your arduino libraries (Sketch -> Import Library -> Add Library)
• Start using it by including "PX4Flow.h" in your project

Example

This example is also available in 'examples/basic/basic.ino'.

#include <Wire.h>
#include "PX4Flow.h"

PX4Flow sensor = PX4Flow(); 

void setup()
{
  Wire.begin();       
  Serial.begin(115200);  
}

void loop()
{
  sensor.update();
  
  Serial.print("#");
  Serial.print(sensor.vx());Serial.print(",");
  Serial.print(sensor.vy());Serial.print(",");
  Serial.println(sensor.altitude());

  delay(100);
}

Support

You can always open an issue on Github and I'll try to follow up. If your issue is related to the PX4Flow hardware, then best is to ask in the user forum on Google Groups.
