hamster Posted December 15, 2014 Share 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 Link to comment Share on other sites More sharing options...
mwagner Posted August 4, 2016 Share Posted August 4, 2016 Can you perform stall detection? Link to comment Share on other sites More sharing options...
JColvin Posted August 15, 2016 Share 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 Link to comment Share on other sites More sharing options...
