diaoul / arduino-maxbotix Goto Github PK

Hi,

I have a problem when use this library, i use two maxbotix in arduino nano, and when i read from Serial, using Rx SoftwareSerial.h, i don't receive anything from Monitor Serie.

But if i use one maxbotix with serial, and another with Digital, the program work without any problem.
This is my code:
#include "Maxbotix.h"
#include <ros.h>
#include <ros/time.h>
#include <sensor_msgs/Range.h>

//Sonar A (EZ4)
//#ifdef MAXBOTIX_WITH_SOFTWARE_SERIAL
Maxbotix rangeSensorTXA(6, Maxbotix::TX, Maxbotix::LV);
//#endif
//Set up the ros node and publisher
sensor_msgs::Range sonar_TXA_msg;
ros::Publisher pub_sonar_TXA("sonarTXA", &sonar_TXA_msg);

//sonar B (EZ0)
//#ifdef MAXBOTIX_WITH_SOFTWARE_SERIAL
Maxbotix rangeSensorTXB(8, Maxbotix::TX, Maxbotix::LV);
//#endif
//Set up the ros node and publisher
sensor_msgs::Range sonar_TXB_msg;
ros::Publisher pub_sonar_TXB("sonarTXB", &sonar_TXB_msg);

ros::NodeHandle nh;

void setup()
{
Serial.begin(9600);
//seleccionamos los pin de control
//Sonar A
pinMode(5, OUTPUT);

//Sonar B
pinMode(4, OUTPUT);

nh.initNode();

//mensaje SERIAL A
nh.advertise(pub_sonar_TXA);
sonar_TXA_msg.radiation_type = sensor_msgs::Range::ULTRASOUND;
sonar_TXA_msg.header.frame_id = "/sonar_range";
sonar_TXA_msg.field_of_view = 0.4;
sonar_TXA_msg.min_range = 0.15;
sonar_TXA_msg.max_range = 6.45;

//mensaje SERIAL B
nh.advertise(pub_sonar_TXB);
sonar_TXB_msg.radiation_type = sensor_msgs::Range::ULTRASOUND;
sonar_TXB_msg.header.frame_id = "/sonar_range";
sonar_TXB_msg.field_of_view = 0.7;
sonar_TXB_msg.min_range = 0.15;
sonar_TXB_msg.max_range = 6.45;
}

long range_timer;

void loop()
{
if ((millis() - range_timer) > 1000)
{
//SERIAL A
digitalWrite(5, HIGH);
delayMicroseconds(50);
digitalWrite(5, LOW);
sonar_TXA_msg.range = rangeSensorTXA.getRange();
sonar_TXA_msg.header.stamp = nh.now();
Serial.print("TXA = ");
Serial.println(sonar_TXA_msg.range);
pub_sonar_TXA.publish(&sonar_TXA_msg);

  //SERIAL B
  digitalWrite(4, HIGH);
  delayMicroseconds(50);
  digitalWrite(4, LOW);
  sonar_TXB_msg.range = rangeSensorTXB.getRange();
  sonar_TXB_msg.header.stamp = nh.now();
  Serial.print("TXB = ");
  Serial.println(sonar_TXB_msg.range);
  pub_sonar_TXB.publish(&sonar_TXB_msg);

  Serial.println(" ");
  range_timer = millis();

}
nh.spinOnce();
}

Thanks so much and sorry for my english.

I am working to use the library to calculate the MB1010 LV-MaxSonar®-EZ1™ range. However, looking through your code, the calculation you make is:

result = toCentimeters(analogRead(pin) / 2.0);

How does the Analog Value In/2 = the value converted to inches? Or is this just a random number that got it close to the actual value but not really?

rangeSensorTx features in both Simple and Advanced examples, but has been disabled in the library files.

You can either remove rangeSensorTX from the examples, or restore RxSoftwareSerial as it has been disabled for a reason not known to me.

Not sure whats going on here, but this is the error that I get when trying to verify the Simple code:

MaxbotixSonar/Maxbotix.cpp.o: In function Maxbotix::getRange()': /usr/share/arduino/libraries/MaxbotixSonar/Maxbotix.cpp:77: undefined reference tooperator new[](unsigned int)'
/usr/share/arduino/libraries/MaxbotixSonar/Maxbotix.cpp:67: undefined reference to `operator delete'
collect2: ld returned 1 exit status

Any help would be greatly appreciated!

I am getting about 7 errors which prevent me from compiling
