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

As you gave no speed requirements and nearly no other informations on your environment:

Try bitbanging the signals.

I'm not sure I'm allowed to put commercial link on this forum

Here are information that I have

Your title is wrong. You need quadrature encoder input, so a quadrature decoder!

Any two channel STM32 timer can act as quadrature decode. Read the reference manual and the timer cookbook about that.
