Sorry about the long absence...I've been on holiday and then getting up to speed on work.
I will be doing some modifications to encoder base module to support multiple types of custom encoders and then will try to integrate these specialized hardware solutions on the modules repo.

I will then look into your G33 modifications. The integration of it might have to be done as a variant option of the G33 as I don't want to disturbed the current G33 version that has been more heavily tested by @HuubBuis

I'm starting to look at this code now. I've finished v1.17 integration. I'm slowly repicking this and looking at the code.
I'll do my best to update this module into the current state of the encoder module.

I'll keep you posted

@staskaaa-netizen I've basically reviewed the code based on the latest changes on µCNC v1.17.0
The following changes were done:

• both ESP32 and RPico HW encoder now support multiple encoders and can be assigned to any µCNC encoder.
• ESP32 and RPico encoders will make use of the same pins used to configure the default encoder (that uses pin interrupt on change) type, and should make configuration more simple.
• both ESP32 and RPico HW encoders can work as a normal quadrature encoder or a simple pulse counter (uses a single GPIO pin to be used as an RPM encoder/meter)
• overlapping functionalities for the HW code with the encoder module was removed (the index ISR handling)
• I've renamed your proposed G33 modifications to g33_els and will keep for now both G33 versions. The current one is working ok and was tested by @HuubBuis . I've also reviewed debug verbose to match the new DEBUG style of µCNC that can be enabled individually by compilation unit.

At this point the only thing remaining testing the modules with the latest adaptations and check if they are ready to be integrated.

Nice ! I will need retest them again on some more hardware. Current esp32 mini encoder emulator was used was reused for mo main hobby. If it is still could be named as a hobby. :
