DRV8825 to replace A4988 - roachslayer - 04-05-2017 05:55 PM

I have some DRV8825 modules. Will these work in place of the A4988 for all of the JJRobots projects?

I found this thread:

Using this with 0.9deg steppers was the goal in the thread above, which requires some code changes. I'm wondering what code changes are needed for standard 1.8deg with this driver.

The most significant difference between the boards is the additional 1/32 step configuration with the mode pins, but I imagine at 1/16 it is "backwards compatible", and the DRV8825 should "just work", right?
