Reverse extruder and calibrate e-steps on btt mini e3v3

[Jeff Nelson]

How do I reverse direction on my extruder? I installed E3V3 mini on ender 3 and a new extruder direct drive. How do I get the source code for that firmware so that I can easily make that change and enter in the new E steps for it?
