How many pulse counter units are used/available for other purposes?

[wiegleyj]

I see that this library connects the PWM output to the pulse counter(s). I also need pulse counters for the other portions of my application. I need only one stepper motor though. The ESP32-S3 has four pulse counter unit. If I setup/use a single stepper motor with this library how many of the four pulse counter units are still available for other uses?

FastAccelStepper allocates one pulse counter per stepper starting with 0. This means pulse counters 1 to 3 are available.

More info is in the readme
