I'm looking at two potential drivers from Anaheim to run a stepper (not doing Big Easy Driver).
Wiring diagrams are shown in the PDF (towards the end of the document).
Is it possible to directly connect the the digital I/O pins to either of these steppers and expect results with the appropriate code? My knowledge of Arduino is very limited and I read that the digital pins run at 5V (so I assume that means 5V logic?).
One is "TTL compatible", which is fine, the other uses opto-isolated inputs which seem to be fine too (check the datasheets for suggested wiring schemes).
I'm sure those are fine drivers but they seem a bit overpriced to me. Check out these: Page Title or if you want the very best, these: http://www.geckodrive.com/categories.html.
All of these drivers take TTL step and direction inputs which the Arduino can provide. OPto-isolation is a good idea as it will protect your Arduino in case something goes wrong.
Thanks for the replies.
Knowing that the Arduino can do TTL, is there anything special I need to do to make it output TTL logic or can I just hook it up as is and start coding?
No, you don't have to do anything other than hook it up to the proper pins. The only possible problem might be if you have a 3.3 V Arduino which may not be compatible with the driver.
