'class HMC5883L' has no member named 'begin'

wasyamsudin · June 7, 2021, 1:53pm

hello, i’m trying to include HMC5883L Compass Library to my code,
i am using the library from jarzebski,, but i always found errors even when i try the example from that library (HMC5883L Calibration), the code is like this

#include <Wire.h>
#include <HMC5883L.h>

HMC5883L compass;

int minX = 0;
int maxX = 0;
int minY = 0;
int maxY = 0;
int offX = 0;
int offY = 0;

void setup()
{
  Serial.begin(9600);

  // Initialize Initialize HMC5883L
  while (!compass.begin())
  {
    delay(500);
  }

  // Set measurement range
  compass.setRange(HMC5883L_RANGE_1_3GA);

  // Set measurement mode
  compass.setMeasurementMode(HMC5883L_CONTINOUS);

  // Set data rate
  compass.setDataRate(HMC5883L_DATARATE_30HZ);

  // Set number of samples averaged
  compass.setSamples(HMC5883L_SAMPLES_8);
}

void loop()
{
  Vector mag = compass.readRaw();

  // Determine Min / Max values
  if (mag.XAxis < minX) minX = mag.XAxis;
  if (mag.XAxis > maxX) maxX = mag.XAxis;
  if (mag.YAxis < minY) minY = mag.YAxis;
  if (mag.YAxis > maxY) maxY = mag.YAxis;

  // Calculate offsets
  offX = (maxX + minX)/2;
  offY = (maxY + minY)/2;

  Serial.print(mag.XAxis);
  Serial.print(":");
  Serial.print(mag.YAxis);
  Serial.print(":");
  Serial.print(minX);
  Serial.print(":");
  Serial.print(maxX);
  Serial.print(":");
  Serial.print(minY);
  Serial.print(":");
  Serial.print(maxY);
  Serial.print(":");
  Serial.print(offX);
  Serial.print(":");
  Serial.print(offY);
  Serial.print("\n");
}

in that case (with calbrating code), i always found error like this
'class HMC5883L' has no member named 'begin'

please help me

Hi @wasyamsudin

When the question is not a good one,
the answer is the worst.....

It means that the class HMC5883L has no member named 'begin'

Please read How to get the best out of this forum

Post your sketch, but don´t forget..

i am using the library from jarzebski, even when i try the example from that library (HMC5883L Calibration), i still find the same error like "has no member 'begin' "

wasyamsudin · June 7, 2021, 2:01pm

oh pardon me, ok i got it

ruilviana · June 7, 2021, 2:03pm

OK, I will teste this example now. (HMC5883L Calibration),
Are you using arduino UNO?

I had no errors compiling this example.

wasyamsudin · June 7, 2021, 2:16pm

i'm using arduino mega sir

wasyamsudin · June 7, 2021, 2:19pm

This is the link to the library I use

ruilviana · June 7, 2021, 2:23pm

@wasyamsudin

I selected Mega Arduino too, and it compiled correctly without errors.

Suggestion, update your HMC5883L library.

What is your IDE version?

wasyamsudin · June 7, 2021, 2:30pm

update version of the library sir?
i'm use IDE 1.8.14

ruilviana · June 7, 2021, 2:34pm

Please, use tags </> and post you erros mensages
