blue led turns on and stays on after begin(). NodeMCU 12E

[nospam2k]

I am loading the driver as follows:

include

include "DRV8825.h"

define MOTOR_STEPS 48

define RPM 20 //200

define ENABLE 15

define DIR 0

define STEP 2

define MODE0 13

define MODE1 12

define MODE2 14

DRV8825 stepper(MOTOR_STEPS, DIR, STEP, ENABLE, MODE0, MODE1, MODE2);

void setup() { stepper.begin(RPM); }

void loop() { }

When I load the sketch, as soon as it runs stepper.begin(RPM) the blue led stays on. No other stepper code is running. If I rem out stepper.begin(), blue led stays off.

Pin 13 is traditionally the LED pin on Arduino, so it might be on or off depending on what MODE0 needs to be at.

Not pin 13 but you did give me what I needed. It is the STEP pin (D4). Thanks! I didn't realize there were two leds in the Nodemcu-12E.
