hamster Posted December 15, 2014 Posted December 15, 2014 Although this isn't using a Digilent FPGA board, here is how to drive a low-cost stepper motor and to count the steps taken. It is using a 5V stepper motor, but if you have 12V motor & driver board it may also work for you. http://hamsterworks.co.nz/mediawiki/index.php/Stepper
JColvin Posted August 15, 2016 Posted August 15, 2016 Hi mwagner, I didn't create the project listed, but looking at the code, I don't think hamster's particular setup supports stall detection since the stepper motor would need to have a couple of I/O lines for feedback, but I'm personally not seeing that. What you would probably need to do is set up some sort of external encoder or detector that checks for either a specified amount of movement or for movement in general that sends back a flag when movement is not as expected. Thanks, JColvin
