It schould be very useful to have a position counter reading for A4988 stepper driver, which shows the actual step between 0 and -1, I use it in FHEM, but PERL is not fast enough to count steps correctly by a subroutine. Ithink, a wemos, an Electrodragon or a Sonoff cpuld handle this.

You can do this electrically. Define counter1 on a gpio and connect the gpio to the pwm. Now you get your counts. Maybe you take a look at the shutter function for stepper motors.
