using functions from a 3rd party library

Projects Programming
1

I'm trying to use a function from a 3rd party library in my arduino program.

I'm not sure what the correct syntax is to call it though. For example, the library name is LowPass, and the function name is FirstOrder()

I tried just calling FirstOrder and then tried calling LowPass.FirstOrder but I'm getting the same error that it wasn't declared. FirstOrder is a void function if that helps.

Thank you!

Look for example sketches at File > Examples > LowPass. They should demonstrate the correct syntax. You also may be able to find documentation for the library. If you downloaded the library then you can look at that same site for the documentation. If you installed the library via Library Manager (Sketch > Include Library > Manage Libraries), by clicking the "more info" link. Also by looking for documentation filed in the library folder.

If all that fails and you still need help then we need a link to the library if you downloaded it or if you installed it via Library manager then say so and provide the full library name.

You need to create an instance of the class:

LowPass filter;

Then, you call methods on that instance:

   filter.FirstOrder();
