what is the max/min RPM limits?

[amrithmmh]

thank you for making this library and found your post on reddit! I want to know how fast(maximum fast say for a 1.2A stepper motor with a4988 driver) and minimum rpm (slowest) it can go?

I read your last post on reddit saying "Marlin printer firmware is more mature and stable" , so my question is why havent you used the code from Marlin firmware(stepper.h and stepper.cpp files in marlin basically)?

thanks again!!

100 was the maximum on my nema13 run by a a4988 - anything beyond just caused weird noises and lost steps.

(just by the way, i also stumbled across this library on reddit and I am thrilled by its simplicity and speed)

A good performance for I/O to control steppers would be something that can deliver around steps with 200 KHz and nearly 0 variations in timming between the steps. Can this lib provide this? Even if needed to use something more powerful than an arduino.
