<http://electronics.stackexchange.com/questions/134356/beaglebone-generate-finite-pulse-train#> I'm wanting to use the BeagleBone Black to generate a FINITE number of pulses, in order to control a stepper motor. For the controller I have, an A4988, each pulse is one step on the motor. How can I use the PWM on the BBB to send, say, 5 pulses, and no more or less than 5? Or I can use a GPIO. Whichever works.
I have the Adafruit BBIO library <https://learn.adafruit.com/setting-up-io-python-library-on-beaglebone-black/using-the-bbio-library> installed. I have thought of doing this in a simple, stupid way - just using python's time.wait() and toggling a GPIO pin, however many times I'd like. But this seems very inaccurate, timing-wise, and moreover inelegant; is there a way to do this better? I'm also investigating events -- i.e., count the numberof pulses that have occured using another GPIO, then stop the PWM when the number of pulses I want has been counted.
