Function generator library

Projects General Guidance
1

I have now tried 2 different versions of rob tillaarts function generator library found and now installed from the library manager. version 0.7.1 and 0.4.3
Keep getting an upload error of 'no such file or directory.'
This could be wrong before set up ' #include <FunctionGenerator.h>'
Could this be expressed wrong here?
Does anybody know what is wrong here? Where is the correct file if in fact there is one?

How did you install the library and where are its files located on the PC ?

Please post your full sketch, using code tags when you do

3 
#include <FunctionGenerator.h>'

Should that be

#include <functionGenerator.h>'

Have you tried the examples that came with with the library ?

Look at the Examples , #include <FunctionGenerator.h> is not in the examples.
Version 0.4.3

  AD.begin();

  AD.setWave(AD9833_SQUARE1);
  Serial.println(AD.getWave());

  AD.setFrequency(1000.0, 0);
  Serial.println(AD.getFrequency(0));

Take a look at the examples in GitHub - RobTillaart/FunctionGenerator: Arduino library to generate wave forms (nummeric) for a DAC such as

//

#include "functionGenerator.h"


funcgen gen;

uint32_t lastTime = 0;
char choice = '0';


void setup()
{
  Serial.begin(500000);
  Serial.println(__FILE__);
  Serial.println("Start ");

  gen.setFrequency(4);
  gen.setAmplitude(50);
}


void loop()
{
  if (Serial.available())
  {
    choice = Serial.read();
  }
  //  wave selection by potMeter
  // int choice = analogRead(A0) / 200;

  float value;
  //  wait for next millisecond;
  if (millis() - lastTime > 0)
  {
    lastTime = millis();
    float t = lastTime * 0.001;
    switch (choice)
    {
      case '0':  value = gen.square(t);   break;
      case '1':  value = gen.sawtooth(t); break;
      case '2':  value = gen.triangle(t); break;
      case '3':  value = gen.stair(t);    break;
      case '4':  value = gen.sinus(t);    break;
      case '5':  value = gen.line();      break;

@petercl14 Exactly which library or libraries are you using ?

6

@petercl14

#include "functionGenerator.h"

and

#include <FunctionGenerator.h

is not the same.

7

The latest release is 0.3.0, see GitHub, so apparently there is something strange.
Can you post the first 10 lines of the .h files of the libraries you use?

Versions 0.7.1 and 0.4.3 don't seem to exist.

The following screen shot shows the versions available from the Library Manager :

Rob himself has confirmed that version 0.3.0 is the latest.
