It doesn't seem to work for 8 wire motors, but for 6 it is fine. Anyone want to help work out the 8 wire part of the script? -- James. -----Original Message----- From: piclist-bounces@mit.edu [mailto:piclist-bounces@mit.edu] On Behalf Of Rikard Bosnjakovic Sent: Thursday, March 06, 2008 10:17 To: Microcontroller discussion list - Public. Subject: [EE] Finding stepper-motor pin configurations So, I got a bunch of stepper motors (unipolar I think, six cables). None of the motors have the same color schemes of the cables, and I have no datasheets. Is there an empirical method to find out which of the six cables is which? -- - Rikard - http://bos.hack.org/cv/ -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
