Using pcnt interrupt and more... about esp32encoder HOT 8 CLOSED

#52

from esp32encoder.

It could be possible to set a custom overflow/underflow value, that would be a matter of changing from a constant to a variable and adding getter/setter to the variable. As for an event called from the ISR, that also is possible if you add a function pointer callback variable to the encoder object and add that event call to the ISR. This is a lot of work modding the library, but nothing you want is impossible. Start a PR and i can help advise you through the changes if you like?

@engineerarslan but the PR hasn't been merged

This feature is in 0.9.0+

from esp32encoder.

Thanks Sir. Your library is great. Can you describe how to use this new feature?

from esp32encoder.

The author of the new feature added an example, but it uses some specific LCD to work. @larroy would you mind making a new example that is only what is needed to demonstrate the feature? mayme measure time between ticks in the interrupt and print that to serial in a slow loop?

from esp32encoder.

Yes I can add another example, also add something to the readme. Just give me a few days since I'm busy with many other things.

For the interest of OPs question, there's a callback in the constructor which you can pass, but be careful since it executes in ISR context, so writing to serial port or other complex stuff can crash the ESP32.
