The analogwave.h library

Development Libraries

Hi

With reference to the above library, could someone list the various commands available for creating various waveforms

Thank you :slight_smile:

Welcome to the forum

As your topic does not relate directly to the installation or operation of the IDE it has been moved to a more relevant category of the forum

As to your question, you can see the functions available if you look at the .h file of the library. The library will also probably come with examples

From the .h file these would appear to be the 3 waveforms available

  void sine(float freq_hz);
  void square(float freq_hz);
  void saw(float freq_hz);

Thank you for the list of three waveforms

Please explain how I can 'look' at this library.....this is why I posted the question in the first place......I do not know how to 'look' at the library

The library is in this path on my Windows PC

C:\Users\Bob2\AppData\Local\Arduino15\packages\arduino\hardware\renesas_uno\1.2.0\libraries

Substitute your Username for mine and change the board release number if you have a different one than me

Many thanks :slight_smile:

One last question relating to this library..................

I am looking through the analogWave.cpp file

and I note the following:-

for each of the three waveforms we have code sections such as..............
static constexpr std::array..................
and
static const std::array

and also
void analogWave::sine.........................for the three sine, saw, square

so my question:
Given this grouping of code for the three waveforms, would it be possible to add in a fourth waveform (e.g. triangle) code grouping - provided one knew what one was doing ?

i.e. to enhance the library to handle four waveforms rather than three

Yes, you can add functionality to the library as long as you know what you are doing. However, be aware that if you do that, then should the library be updated your additions will be lost

You might be better off copying the library code to a different name and making changes to that

Thank you very much.........
