STM32 as quadrature encoder output

Hi everyone,

I need to reed a quadrature encoder signal from a sensor, modify the number of pulse and send this signal out to a machine.

The output signal must be a TTL quadrature signal, I have 5 pins: 0v, 5v, A, B and Z on my machine.

All the reading part is OK but I don't know how I should do for sending exact amount of pulse with quadrature signal.

Thank you for your help

The data above seems for the encoder and it has 0.1 mic, 0.5mic, 1mic, 2mi resolution.

I bought nothing yet, I just want t develop something. unfortunately, I don't have the choice of the encoder, and none of cheap DRO are able to accept this resolution, this is why I try to figure out something with STM32

The display for the STm32 is my last option but I would very very very like to have a normal DRO.

Thank you for your help

I made huge progress from yesterday.

Now I try to manipulate bitwise in order to have for channel A/B when positive pulse:

0/0

1/0

1/1

0/1

0/0

etc

and reverse when negative pulse. But I'm not familiar with bitwise manipulation yet
