TMC2209 is an ultra-silent motor driver IC for two-phase stepper motors. Its continuous drive current is 2A and peak current is 2.8A. Compared with TMC2208, the driving current of this IC is not only improved by 0.6a-0.8a, but also this IC increases the function of locked-motor test.

I have TMC2209 v1.2 drivers connected to Ramps 1.4. Everything works fine except ability to trigger end-stops using sensor less homing Can somebody tell how to connect BTT tmc2209 v1.2 diag pin to ramps 1.4 end-stop pin ?

Here is the Pin info from the datasheet: DIAG 11 DO Diagnostic and StallGuard output. Hi level upon stall detection or driver error. Reset error condition by ENN=high.
