AX58100

Yes this is my goal, everything on a same board.
IC-NV part is not easy but one from PEdpex is working so I should use the same.
There is not much chip that can do this as good as IC-NV so I might stick to this one.
And STM32F4 works good for encoders so it should be a good match.
I will try to start from your E7000 then thank you

@Hakan certainly a stupid question but I did not understood why you did not managed to get the encoder work on the ethercat devboard here?



I wanted to test the encoder on the devboard before doing a custom board
Thank you for the clarification

Haha, that brings back memories image missing /media/kunena/emoticons/smile.png

There are two products here in the picture

The STM32's pins on the LAN93252 dev board are limited to those in the pin header, which wasn't enough.
For test it can work if the needed pins are available in the header.
One can use the LAN9252 of the kit, which is what I did and hooked it up to the STM32 dev board
where I had access to all pins.SPI+sync0,syc1,irq lines.

I now see in some searches there are other LAN9252+STM32 development boards which are better suited, maybe this one?
 
It can pay off to do a search. You want access to the Timer's encoder inputs, which 
are different for different models so it's a puzzle.

Hello
I bought the following card (still waiting for it) and it seems to have TIM8 CH1 and CH2 available
fr.aliexpress.com/item/1005008473184616....gatewayAdapt=glo2fra  

That should work. It's a 16-bit encoder counter so be prepared to handle overflow.
TIM2/TIM5 are 32-bit so better to use that when you do your own. There is only one 32-bit though.
 

Hello,
Not sure to understand correctly:
You can have both TIM2 and TIM5 32bits encoders running in the same time right?
But it has to be on a custom board
