get_opt_flow_position()

Description

This function gets the x and y coordinates from the optical flow sensor.
Keep in mind, the positioning does not take rotation into account.

Syntax

Python: get_opt_flow_position()
Arduino: getOptFlowPosition()

Parameters

None

Returns

Outputs to visual UI. In code, it returns a class in Python and struct in Arduino.

Example Code

Python

#Python code

import CoDrone

drone = CoDrone.CoDrone()

drone.pair()

# print the optical flow position x,y value

position = drone.get_opt_flow_position()

print(position.X, position.Y)

drone.close()

Arduino

//Arduino code

//Code for print request data to serial monitor

#include<CoDrone.h> //header

void setup(){

//open serial and connect

CoDrone.begin(115200);

CoDrone.pair(Nearest);

}

void loop(){

// Struct for get optical flow sensor data

optdata opt;

CoDrone.Send_LinkModeBroadcast(LinkBroadcast_Active); //link module mode change => Active

opt = CoDrone.getOptFlowPosition(); //save request data

delay(100);

CoDrone.Send_LinkModeBroadcast(LinkModeMute); //link module mode change => Mute

delay(100);

Serial.println("");

Serial.println("--------- Now -----------");

Serial.print("opt x : \t");

Serial.println(opt.x);

Serial.print("opt y : \t");

Serial.println(opt.y);
