Glitch filtering about pigpio

[fivdi]

Currently this isn't possible.

It looks like it would be relatively easy to add.

This is good news. Similar to glitch filtering is the gpioNoiseFilter.
Unfortunately I have no experience with native bindings in node, so I will have to catch up on that before attempting a PR.

I also needed this feature, so I've decided to add it: #50

@DvdBerg @marcinbudny [email protected] was just published on npm has a new glitchFilter method.

@DvdBerg Thank you very much to taking the time to create the pull request.

What about the gpioNoiseFilter? Using a RF433 receiver will cause thousands of noise interrupts per seconds killing the cpu of my Rasperry Pi.

As mentioned above gpioNoiseFilter is supported. Please take a look at the documentation.

Please point me to the document in https://github.com/fivdi/pigpio? I can't find it in the npm project

Sorry, my mistake, the title of this issue is "Glitch Filtering" so I assumed you were asking about glitch filtering and now see that you are asking about noise filtering. gpioNoiseFilter isn't actually supported by this Node.js module at this time. Only glitch filtering is supported.

Please note that the documentation for the pigpio C library functions gpioGlitchFilter and gpioNoiseFilter state that calling these functions has no affects on interrupts. Calling them does however have affects on alerts.

[louisvangeldrop]

I am using the alert function.

Would you like to create a PR for adding gpioNoiseFilter?

[louisvangeldrop]

No idea how to do that. I have no experience in C++ programming
