FreqMeasure Library Error(s)

Projects Programming
1

Okay, so I am encountering problems with using the FreqMeasure library.
Its hard to explain so here is some pictures of the situation and the errors that I am getting from the terminal of the Arduino IDE.

Upon initially encountering the problem I immediately assumed that the version of the library I installed from the Library Manager is broken. Because not only was I having errors in the terminal, the example or example codes are also not working.

So, I resorted to downloading the version of the FreqMeasure library from Github instead.
The example code are working this time. But I am still getting the same errors in my terminal as before.

Now I wonder do you guys get the same error? So here I am hoping anyone of you could help me with this. I would like to know you guys' input as to what exactly is the problem here and what the solution is. Thanks in advance for those who would like to help!

PS: I am using an ESP32 as my microcontroller.

Your topic was MOVED to its current forum category which is more appropriate than the original as it has nothing to do with Installation and Troubleshooting of the IDE

Please do not post pictures of errors. Use the "Copy errors" button in the IDE and post them here using < CODE/ > tags

Which Arduino board are you using ?

Yes, we're getting the same error here because we can't identify what board you're using ...

I am beginner and I admit that its frustrating trying to navigate these things, I apologize. Yes, I am using an ESP32 dev module. Is the error I'm getting related to the microcontroller I am using? Because I don't think so... If it is, kindly tell me what I can do to fix it and I would really appreciate the help!

Yes, its not compatible with the ESP32.

What signal signal do you want to measure?
(a description of your project would help)

I'm planning to use the FreqMeasure library to supposedly test whether my HB100 radar sensor, with an lm358 op-amp to amplify the signal, is properly working. I saw online that people use FreqPeriod or FreqCount to do this. So what I intended to use the FreqMeasure is for measuring the frequency of the moving object detected by the sensor and by extension its velocity as well.

Okay, so the ESP32 is not compatible with the FreqMeasure library right? But its weird...
I am getting the error even if I just try to verify the code and not even upload it to the ESP32. Which sounds to me that the error that I am getting is not due to the ESP32 board itself but that the library I am using is just broken. But I don't know, maybe I am overthinking this and I should just try to move on to the alternatives.

I have not seen a frequency measure library for any ESP chip. AFAIK, they work only on a few specific AVR MCUs.

Definitely works on the ARM-based Teensy boards.

Not "weird" at all. "Not Compatible" means ESP has different timer hardware configuration. So access to hardware-specific registers won't compile.

Perhaps this would work ... Frequency Measurement on digital input
